Luxury Concierge Services

REAL ESTATE — LUXURY VILLA, PENTHOUSE & DUPLEX RENTAL 

Black Diamond Holding Group Limited offers an elite, fully curated luxury real estate rental service across the most prestigious addresses on the French Riviera, Monaco, and London — giving ultra-high-net-worth clients exclusive access to villas, penthouses, duplexes, and private estates that are never listed on the open market.
Our off-market real estate portfolio spans the finest properties the Côte d’Azur has to offer: sun-drenched villas perched above the Bay of Cannes with panoramic sea views, sleek contemporary penthouses in Monaco’s coveted Monte-Carlo district, and opulent Belle Époque residences nestled in the hills of Cap Ferrat, Cap d’Antibes, and Èze. Whether you are seeking a palatial five-bedroom estate for the Cannes Film Festival, a discreet luxury apartment for the Monaco Formula 1 Grand Prix, or a private villa for an extended summer season on the Riviera, our concierge team sources and secures the property that perfectly aligns with your specifications.
Unlike conventional real estate agencies, Black Diamond operates at the intersection of exclusivity and confidentiality. The majority of the properties we represent are off-market: they are available only to clients introduced through our network and are never advertised publicly. This gives our clients access to a level of property quality, privacy, and uniqueness that is simply unavailable through traditional channels.
Our service is entirely bespoke. We take the time to understand your requirements in full — budget, preferred dates, desired location, architectural style (contemporary, Provençal, art deco, baroque), surface area, number of bedrooms, service staff requirements, security infrastructure, and proximity to private marinas, helipads, or airports. We then leverage our established network of property owners, private family offices, and luxury real estate specialists across London, Monaco, Cannes, Saint-Tropez, Nice, and Cap d’Antibes to present you with a hand-selected shortlist within the shortest possible timeframe.
All negotiations, due diligence, and contractual arrangements are handled discreetly and professionally by our team, ensuring a seamless, white-glove experience from first contact to the moment you step through the door. On-site staffing — private chefs, housekeeping, security, and personal assistants — can be arranged as part of an integrated lifestyle package.
For clients who prefer to explore ownership rather than rental, our team also provides confidential advisory on off-market property acquisitions in Monaco, Cannes, and London, including guidance on purchasing French real estate with cryptocurrency — a specialisation that positions Black Diamond at the forefront of the emerging luxury crypto-real estate market.
Enquire in complete confidence. Access is by invitation only. Absolute discretion is guaranteed.

LUXURY YACHT RENTAL — SUPERYACHT CHARTER FRENCH RIVIERA

Black Diamond Holding Group’s yacht concierge division provides access to one of the most exclusive fleets of private yachts and superyachts available for charter in the Mediterranean — ranging from elegant 20-metre motor yachts to breathtaking mega-yachts exceeding 100 metres in length.
Our yacht charter service covers every aspect of your time on the water: whether you wish to host a private event at anchor in the Bay of Cannes during the Film Festival, entertain VIP guests aboard a superyacht in Monaco’s harbour during the Formula 1 Grand Prix, or embark on an extended Mediterranean cruise from Cannes to Saint-Tropez, Portofino, Sardinia, or the Amalfi Coast, we have the knowledge, the network, and the relationships to make it happen.
We offer both berth charters — where your yacht is moored in a prestige marina for use as a floating private club or entertainment venue — and blue-water charters where you set sail at your own pace and on your own itinerary. All vessels in our portfolio are meticulously maintained, fully certified, and available with complete professional crew including a qualified captain, first mate, chef, stewards, and deck crew.
Catering and on-board hospitality are a particular area of expertise. We work with Michelin-starred private chefs and experienced marine catering specialists to deliver bespoke menus, fine wine selections, and gourmet provisioning tailored precisely to your tastes and dietary requirements. Whether you prefer an intimate dinner for two under the stars or a lavish cocktail reception for fifty guests, our culinary team will exceed your expectations.
Our yacht charter offer covers all of the Mediterranean’s most coveted destinations: Monaco, Cannes, Nice, Saint-Tropez, Antibes, Menton, the Italian Riviera, Corsica, Sardinia, Ibiza, Mallorca, and the Amalfi Coast. Charter periods range from a single day to an entire season, with flexible terms to accommodate spontaneous requests or long-term planning.
For the Monaco Yacht Show, Cannes Film Festival, and Monaco Grand Prix — three of the world’s most prestigious and sought-after events — we provide specialist VIP yacht charter packages that combine prime berth positions, exclusive on-board event production, and full concierge support.
Quotes are prepared on request, tailored to your vessel preference, charter duration, crew configuration, and destination. All requests are treated with the utmost confidentiality.

Our professional drivers are not simply chauffeurs — they are discreet personal assistants on wheels. Rigorously selected, fully licensed, and fluent in English and French (with additional languages available on request), our drivers are trained in defensive driving, VIP protocol, route optimisation, and client confidentiality. They are punctual, immaculately dressed, and entirely focused on delivering a smooth, stress-free journey from the moment of pick-up to the moment of arrival.
We provide chauffeur-driven luxury vehicles for airport and heliport transfers to and from Nice Côte d’Azur Airport, Monaco Héliport, and Cannes-Mandelieu Airport; for full-day and multi-day hire throughout the Riviera; for hotel-to-hotel transfers, restaurant and event transportation, shopping excursions, and business travel; and for comprehensive ground logistics during major events including the Cannes Film Festival, Monaco Formula 1 Grand Prix, and Monaco Yacht Show.
Our chauffeur service can be booked for a few hours, a full day, a weekend, or the entire duration of your stay in the region. For clients requiring a seamless door-to-door luxury experience — from private jet arrival to yacht boarding — we work in close coordination with our aviation and yacht concierge teams to deliver fully integrated itineraries with zero gaps and zero compromises.

PRIVATE JET BOOKING — CHARTER FLIGHTS FROM LONDON – CANNES · NICE · MONACO 

Black Diamond Holding Group offers a world-class private jet booking and charter concierge service, giving ultra-high-net-worth clients seamless access to a vast global fleet of private aircraft — from nimble light jets for short-haul European hops to ultra-long-range heavy jets for transcontinental travel in absolute comfort and style.
Through our exclusive partnership with one of Europe’s most respected private aviation charter operators, we are able to source, book, and coordinate private jet charters from any departure point to any destination worldwide, with response times measured in hours rather than days.

We work with a curated network of operators whose aircraft meet the most stringent safety and quality standards. Every aircraft recommended through our service holds the appropriate airworthiness certificates, is operated by experienced licensed flight crews, and is subject to rigorous ongoing maintenance protocols. Safety is never compromised.
Our private jet offer covers the full spectrum of aircraft categories: turboprops and very light jets for short regional trips, midsize jets for intra-European travel, super-midsize and large cabin jets for longer European routes, and ultra-long-range aircraft including the Gulfstream G650, Bombardier Global 7500, and Dassault Falcon 8X for intercontinental travel to the Americas, Middle East, or Asia.
For clients based on the French Riviera, we specialise in charters operating from Cannes-Mandelieu Airport (one of the most exclusive private aviation hubs in Europe), Nice Côte d’Azur Airport, and Monaco Héliport, with helicopter transfers coordinated to seamlessly connect yacht arrivals, villa check-ins, and onward jet departures.
Key services include: one-way charter bookings, return trip arrangements, multi-leg itineraries, in-flight catering and cabin customisation, ground transportation coordination at origin and destination, and identification of empty leg opportunities to deliver best-in-class value for flexible itineraries.
Whether you are flying into Cannes for the Film Festival, into Monaco for the Grand Prix, or departing the Riviera at the close of the summer season, our aviation concierge team handles every detail — from aircraft selection to immigration documentation to on-board champagne selection — so that your journey begins the moment you leave your villa or yacht.

SPORTS CAR & SUPERCAR RENTAL — CANNES · MONACO · FRENCH RIVIERA

Few experiences on the French Riviera match the sensation of driving a world-class supercar along the legendary coastal roads of the Côte d’Azur — and Black Diamond Holding Group’s sports car and exotic vehicle rental service gives our clients exactly that, with access to some of the most desirable and exclusive performance automobiles in the world.
Our supercar fleet encompasses the finest marques in contemporary and classic performance motoring: Ferrari, Lamborghini, McLaren, Porsche, Aston Martin, Bugatti, Bentley Continental GT, Mercedes-AMG, BMW M-Series, and more. Whether you are searching for the visceral excitement of a track-focused hypercar or the effortless grand touring comfort of a high-performance convertible for a sunset drive along the Croisette or the Grande Corniche, our concierge team will identify the perfect vehicle for your desires.
All vehicles in our portfolio are meticulously maintained, fully insured, and presented in immaculate condition at your preferred location — whether that is your villa, hotel, yacht berth, or private jet terminal. Delivery and collection can be arranged anywhere across the French Riviera, including Cannes, Monaco, Nice, Antibes, Saint-Tropez, and Menton.
We offer sports car rental by the day, the weekend, or for the full duration of your stay. For clients attending major events on the Riviera — the Monaco Formula 1 Grand Prix, the Cannes Film Festival, or the Monaco Yacht Show — a supercar is not merely transport; it is an expression of identity. Our event-period bookings are managed with priority availability and include the option of combining your supercar rental with a professional chauffeur driver, allowing you to arrive in style while your driver handles parking and logistics.
For those who wish to push their vehicles to the limit in a controlled environment, we can also coordinate private track experiences at nearby circuits on request.

LUXURY WATCH ACQUISITION & COLLECTOR’S TIMEPIECE SOURCING

For collectors, connoisseurs, and investors who understand that the finest timepieces are rarely found in a boutique window, Black Diamond Holding Group offers a discreet, expert, and entirely bespoke luxury watch acquisition concierge — providing privileged access to the most coveted, rare, and high-value timepieces in the world.
Our network of trusted horological specialists, private collectors, auction houses, and certified watch dealers spans Geneva, London, Monaco, Hong Kong, Dubai, and beyond. This gives us the ability to source watches that simply cannot be found through conventional retail channels — including models with multi-year waiting lists, one-of-a-kind commissioned pieces, vintage references in exceptional condition, and investment-grade collector’s timepieces from the world’s most prestigious maisons.
Among the houses we regularly source across include: Patek Philippe, Rolex, Audemars Piguet, Richard Mille, A. Lange & Söhne, F.P. Journe, Vacheron Constantin, Jaeger-LeCoultre, Cartier, Breguet, Hublot, and a curated selection of independent high-horology brands producing timepieces in strictly limited numbers. Whether you are searching for a Patek Philippe Nautilus reference 5711 in stainless steel, a Richard Mille RM 11-03 in NTPT carbon, or a vintage Rolex Daytona Paul Newman in verified original condition, our team will conduct a thorough and confidential search on your behalf.
Every acquisition conducted through our service is subject to a rigorous provenance and authenticity verification process. We work exclusively with certified specialists and trusted partners who adhere to strict standards of transparency, documentation, and legal compliance. Anti-money laundering protocols are observed in full at every stage.
Beyond acquisition, our watch concierge service extends to portfolio advisory — helping discerning clients build, diversify, or rationalise collections of investment-grade timepieces with a view to both aesthetic enjoyment and long-term capital appreciation. The luxury watch market has demonstrated remarkable resilience and growth as an alternative asset class, and our team provides clients with the market intelligence, access, and discretion to navigate it with confidence.
This service connects directly with our broader investment advisory division, where luxury assets — including watches, fine art, classic automobiles, and rare wines — are evaluated as components of an integrated alternative investment strategy.

BODYGUARD, CLOSE PROTECTION & PERSONAL SECURITY ESCORT SERVICES

Black Diamond Holding Group provides access to a rigorously vetted, fully professional close protection and personal security escort service for ultra-high-net-worth individuals, public figures, corporate executives, and their families — offering peace of mind without compromising discretion, freedom of movement, or the luxury experience.
Our close protection agents are recruited exclusively from the highest levels of military, law enforcement, and specialist security backgrounds. All agents hold the relevant professional accreditations and licenses required to operate in France, Monaco, and the United Kingdom, and are subject to ongoing vetting and skills assessment. They are experienced in static and mobile close protection, threat assessment, advance reconnaissance, hostile environment operations, emergency medical response, and VIP protocol.
What distinguishes our security concierge service from conventional personal security providers is the seamless integration of professional protection within the lifestyle our clients expect. Our agents are not imposing — they are trained to blend into high-profile social environments, luxury venues, superyacht settings, private events, and public-facing situations while maintaining the highest levels of vigilance at all times. They present immaculately, conduct themselves with absolute professionalism, and are briefed to the finest detail on client preferences, itineraries, and requirements before deployment.
We provide close protection services for the full range of client scenarios: short-term engagements for major events including the Cannes Film Festival, Monaco Formula 1 Grand Prix, and Monaco Yacht Show; extended stays on the French Riviera or Monaco during the summer and winter seasons; business travel escorts across Europe and beyond; security for high-value transactions including art acquisitions, watch purchases, and real estate viewings; and 24/7 residential security arrangements at private villas, penthouse residences, and superyachts.
Our protection packages are offered at various tiers — from a single experienced close protection officer accompanying a client throughout their stay to a full multi-agent team covering all members of a family or business delegation, with integrated advance security, vehicular counter-surveillance, and communications infrastructure. We can also coordinate directly with your existing in-house security team to provide local expertise, regional intelligence, and specialist augmentation.
All engagements are conducted under a comprehensive non-disclosure agreement, and client identities are protected at every stage of engagement. We never discuss past or present clients, and our agents operate to a standard of confidentiality that reflects the values of Black Diamond Holding Group as a whole.
Request a confidential security briefing. Our team will design a bespoke close protection package tailored to your profile, itinerary, and risk environment.
