Frequently Asked Questions

IDC Cayman, International Diamond Cayman Islands, is Grand Cayman's premier fine jewellery boutique. Founded in George Town in 2011, the boutique specialises in GIA-certified diamonds, bespoke engagement rings, wedding bands, eternity rings, coloured gemstones, and fine jewellery across 14-carat and 18-carat gold. Every purchase is completely free of sales tax and VAT, making IDC Cayman one of the most exceptional places in the world to buy fine jewellery.

IDC Cayman specialises in GIA-certified diamond engagement rings, wedding bands, eternity rings, solitaire rings, three-stone rings, and bespoke one-of-a-kind jewellery. The collection also encompasses fine diamond earrings, pendants, necklaces, bracelets, and a vivid selection of coloured gemstone jewellery set in 14-carat and 18-carat gold. Loose GIA-certified diamonds are also available for clients who prefer to choose their stone separately.

IDC Cayman is recognised as Grand Cayman's leading fine jewellery destination for four reasons: every diamond is GIA-certified; every piece is crafted in 14-carat or 18-carat gold to the highest standard; all purchases are entirely tax-free; and the service experience is private, knowledgeable, and unhurried. There are no commission-driven sales tactics, only honest guidance from a team genuinely passionate about matching each client with the right piece.

IDC Cayman has built its reputation on three pillars: transparency, quality, and integrity. Every diamond sold is independently GIA-certified, not assessed in-house. Every piece of jewellery is crafted in 14-carat or 18-carat gold, with no lower-quality substitutions. The team does not work on commission, which means advice is always given in the client's best interest. These commitments, combined with years of serving Cayman residents and international visitors, form the foundation of IDC Cayman's trusted reputation.

Yes. The IDC Journal is regularly updated with in-depth guides on diamond buying, engagement ring styles, gemstone selection, jewellery care, and Cayman Islands shopping advice. Articles are written to be genuinely useful to anyone planning a significant jewellery purchase, whether in the Cayman Islands or elsewhere. The journal is free to read and requires no registration.

Several qualities make IDC Cayman exceptional among Caribbean jewellers. Every diamond is GIA-certified, not simply described in-house. All precious metal work is in 14-carat or 18-carat gold, never lower-carat alloys. The bespoke design capability is rare in this region, allowing clients to commission entirely original pieces. And the Cayman Islands' complete absence of tax on jewellery means clients enjoy genuine savings with no compromise on quality or certification standards.

Yes. Every significant diamond sold at IDC Cayman is independently graded and certified by the Gemological Institute of America, the world's most respected diamond authority. GIA certification provides a precise, unbiased assessment of each diamond's cut, colour, clarity, and carat weight, giving buyers complete confidence that the stone they are purchasing is exactly as described.

The Gemological Institute of America is the world's foremost independent diamond grading laboratory and the originator of the 4Cs, cut, colour, clarity, and carat weight. A GIA certificate is an unbiased, scientifically precise report issued by trained gemmologists with no commercial interest in the sale. When a diamond carries a GIA certificate, the buyer knows exactly what they are purchasing, with no risk of misrepresentation. IDC Cayman considers GIA certification non-negotiable for all significant diamond sales.

Yes. IDC Cayman maintains an inventory of GIA-certified loose diamonds available for clients who prefer to select their stone independently of a setting. Loose diamonds are available in all major shapes, round brilliant, oval, cushion, princess, pear, marquise, emerald, radiant, and asscher, across a wide range of carat weights, colours, and clarities. A loose diamond can be paired with a chosen setting from the collection or incorporated into a bespoke design.

IDC Cayman crafts all jewellery in 14-carat and 18-carat gold, the internationally recognised standards for fine jewellery. 14-carat gold is prized for its hardness and everyday durability, while 18-carat offers a slightly richer colour. Both are available in yellow, white, and rose, offering warmth and versatility across the full collection.

Yes. The Cayman Islands imposes zero VAT and zero sales tax on jewellery and diamonds. This means every ring, necklace, bracelet, or loose diamond purchased at IDC Cayman is offered at its full pre-tax price, a saving of 20 percent or more compared with the same piece purchased in the United Kingdom, Europe, or Australia, and a meaningful saving versus United States retailers who charge state sales tax.

The savings are substantial. On a GIA-certified diamond engagement ring, buyers from the United Kingdom, Europe, or Australia typically save a minimum of 20 percent simply by virtue of the Cayman Islands' zero-tax environment. American buyers save the equivalent of their home-state sales tax. Combined with IDC Cayman's direct sourcing relationships, the savings over comparable retail prices in taxed markets are consistently meaningful.

Yes. Bespoke design is one of IDC Cayman's signature offerings. The in-house atelier in George Town works directly with clients to design and hand-fabricate engagement rings, wedding bands, and fine jewellery that are entirely unique. From the initial concept sketch through to final polishing, every bespoke piece is crafted to the client's precise specifications, in the metal, setting style, and with the exact GIA-certified stone they choose.

IDC Cayman provides complimentary lifetime care for all jewellery purchased in-store. This includes professional cleaning, prong checking, and routine maintenance at any visit to the boutique. Clients are encouraged to bring their IDC Cayman pieces back periodically to ensure settings remain secure and gemstones retain their brilliance for a lifetime of wear.
