Diamond Jewellery in Grand Cayman

Diamond necklaces, earrings, bracelets and rings — GIA-certified brilliance, entirely tax-free.

There is a reason diamonds have never gone out of style: nothing else catches the light, or the eye, in quite the same way.

IDC Cayman's diamond jewellery collection reaches far beyond the engagement ring. Diamond stud earrings, tennis necklaces and bracelets, pendants and pave designs — brilliance for every day and every occasion.

Every diamond is independently GIA-certified, every piece is crafted in platinum or 18-carat gold, and everything is offered entirely free of duty and tax in Grand Cayman.

The Collection

Brilliance for Every Day

Diamond studs that finish any outfit. A tennis necklace that catches every light. A diamond bracelet that transforms the wrist. These are the pieces a jewellery wardrobe is built around — worn alone, or layered together.

Each is designed to be worn and loved, not locked away for best.

How do I choose the right diamond?
Our experts will guide you through the 4Cs and help you balance these qualities for the best beauty within your budget.
What is the most important of the 4Cs?
Cut is generally considered the most important, as it determines how powerfully a diamond returns light as fire and sparkle.

Do you offer diamond tennis bracelets?
Yes. Our collection includes beautiful diamond tennis bracelets in a range of carat weights and settings.

Can diamond jewellery be resized or adjusted?

How should I care for diamond jewellery?
Clean diamond jewellery regularly with warm water and mild dish soap. Bring it in annually for professional cleaning and prong inspection.
Do you offer diamond jewellery for everyday wear?

Yes. We can source natural coloured diamonds by arrangement. Please contact us to discuss your requirements.
What metal options are available?
Platinum, 18-carat yellow gold, 18-carat white gold and 18-carat rose gold are all available.

Both are beautiful choices. Platinum is more durable and never needs replating. White gold is lighter and slightly more affordable.

Yes. Complimentary professional cleaning and inspection is available for the lifetime of any piece purchased at IDC Cayman.
