Colored Gemstone Rings and Jewelry in Grand Cayman

Sapphires, emeralds, rubies, tanzanite and rare colored stones, set in 14-carat and 18-carat gold.

The Collection

Nothing Captures the Caribbean Like Color

Diamonds may be forever, but color is where personality lives. Our colored gemstone collection runs from sapphire and emerald to ruby, tanzanite and a wide range of fine semi-precious stones, each chosen for the intensity and life of its color.

Every gemstone is set to the same exacting standard as our diamonds, in 14-carat and 18-carat gold, as a statement cocktail ring, a colored gemstone engagement ring, or a piece designed entirely around a single stone you fall for.

Colored gemstone engagement rings and one-of-a-kind statement pieces are available from the collection and through bespoke commission, including jewelry set with Cayman's own caymanite.

The Stones

Our Favorite Colored Gemstones

From sapphire, emerald and ruby to tanzanite, alexandrite and Cayman's own caymanite, these are the colored gemstones we love to set.

Sapphire

Beyond classic blue, sapphires run through pink, teal, yellow and the rare padparadscha. At 9 on the Mohs scale they wear well every day, which makes a sapphire ring a favorite for engagements.

Emerald

The green of the tropics. Emerald jewelry is prized for depth of color and a soft, romantic glow, and we set emeralds in protective styles built for real life.

Ruby

The most intense red in nature. A ruby ring is bold, rare and, as corundum, hard enough to wear often.

Tanzanite

A violet-blue found only near Kilimanjaro and rarer than diamond. Tanzanite jewelry and tanzanite rings shine in earrings, pendants and occasion pieces.

Alexandrite

The color-change marvel: green in daylight, red under lamplight. Natural alexandrite is one of the rarest stones we source.

Aquamarine and Blue Topaz

Cool sea-blue aquamarine and bright blue topaz, two clean, wearable blues that suit rings and pendants alike.

Opal, Peridot and Garnet

Play-of-color opal, fresh green peridot and deep red garnet, characterful stones with real personality.

Morganite, Citrine and Amethyst

Blush morganite, warm golden citrine and royal purple amethyst, soft romantic colors for rings and everyday pieces.

Caymanite

Cayman's own stone, banded in cream, gold and rust from our island cliffs. Caymanite jewelry is a keepsake you can buy nowhere else.

Ammolite and Coral

Iridescent ammolite and warm Caribbean coral, rare organic gems that carry the color of the sea and shore.

Gemstone Guide

A Guide to Colored Gemstones

Sapphire

Sapphire is the most popular colored gemstone we set, and for good reason. At 9 on the Mohs hardness scale it is second only to diamond, so a sapphire ring holds up to everyday wear. Most people picture deep blue, but sapphires also come in pink, teal, yellow, green and the rare pink-orange padparadscha, which makes them a favorite for colored engagement rings.

Emerald

Emerald is the green of the tropics, prized for the depth and glow of its color. Emerald jewelry rewards a little care, since the stone is softer and more included than sapphire, so we favor protective settings and save emerald rings for gentler wear. Earrings and pendants show an emerald off beautifully.

Ruby

Ruby is the most intense red in nature and, like sapphire, it is corundum at hardness 9, so a ruby ring is tough enough to wear often. Fine ruby is rarer than diamond in large sizes, which is part of its lasting appeal for statement rings and anniversary pieces.

Tanzanite

Tanzanite is a velvety violet-blue found in only one place on earth, near Mount Kilimanjaro, which makes it far rarer than diamond. It is softer than sapphire, so tanzanite jewelry and tanzanite rings look their best in earrings, pendants and occasion rings rather than a ring worn every day.

Alexandrite

Alexandrite is the color-change marvel of the gem world, green in daylight and red under warm lamplight. Fine natural alexandrite is one of the rarest colored gemstones in existence, and we can source certified stones for a truly one-of-a-kind ring.

Aquamarine and Blue Topaz

For cool, clean blues, aquamarine and blue topaz are hard to beat. Aquamarine carries the pale sea-blue of the Caribbean and is durable enough for everyday rings, while a bright blue topaz gives a similar look at a friendly price, ideal for pendants and cocktail rings.

Opal, Morganite, Peridot, Citrine, Garnet and Amethyst

These are the stones our clients reach for when they want color with personality. Opal flashes a play of color all its own, morganite glows soft blush pink, peridot is fresh spring green, citrine warm gold, garnet deep red, and amethyst rich royal purple. Each makes an affordable, wearable ring or pendant.

Caymanite, Cayman’s Own Stone

Caymanite is Cayman’s own stone, a rare banded rock found only in these islands, layered in cream, gold, brown and rust like the cliffs it comes from. Because you can find it nowhere else, a piece of caymanite jewelry is one of the most meaningful things to carry home from Grand Cayman, and one of the few gems we can call truly local.

Ammolite and Coral

Ammolite and coral are organic gems with the color of the sea. Ammolite shimmers with iridescent reds, greens and golds, while warm Caribbean coral has been worn as jewelry for centuries. Both make distinctive, island-inspired pieces.

Custom Colored Gemstone Rings

If you have a stone or a color in mind, we design custom colored gemstone rings from scratch in our George Town atelier. We source the gemstone to your color, size and budget, then build the setting around it in 14-carat or 18-carat gold, from a single-stone cocktail ring to a gemstone-and-diamond design that is entirely your own.

Questions

Good to Know

Are colored gemstones a good choice for an engagement ring?
Yes. Colored gemstone engagement rings are more popular every year for their individuality. Sapphire is an excellent everyday choice, at 9 on the Mohs hardness scale it is second only to diamond, so it stands up to daily wear. Emerald and softer stones are better kept for rings you wear less often, or for earrings and pendants.
What is caymanite?
Caymanite is a rare banded stone found only in the Cayman Islands, layered in cream, gold, brown and rust. Because it is unique to these islands, a piece of caymanite jewelry is a true keepsake you can buy nowhere else. We set caymanite in rings, pendants and other fine pieces in 14-carat and 18-carat gold.
What is tanzanite?
Tanzanite is a violet-blue gemstone found in only one place on earth, near Mount Kilimanjaro in Tanzania, which makes it far rarer than diamond. It is softer than sapphire, so tanzanite jewelry looks its best in earrings, pendants and occasion rings rather than a ring worn every day.
What is alexandrite?
Alexandrite is famous for changing color, green in daylight and red under warm indoor light. Fine natural alexandrite is one of the rarest colored gemstones in the world, and we can source certified stones on request.
Which gemstones are durable enough for everyday wear?
Sapphire and ruby, both corundum at hardness 9, are the most durable colored gemstones for daily wear. Emerald and softer stones such as tanzanite and opal are more delicate and are best set in earrings, pendants or occasion rings rather than an everyday ring.
How do I know a gemstone's color is natural?
Most fine gemstones receive standard, stable treatments such as heat that are disclosed as a matter of course. For significant stones we can provide independent laboratory reports confirming the stone's identity and any treatment, so you know exactly what you are buying.
What is a padparadscha sapphire?
Padparadscha is a rare and highly prized sapphire in a delicate blend of pink and orange, named after the lotus flower. Genuine padparadscha sapphires are among the most collectible colored gemstones in the world.
Can you create a custom colored gemstone ring?
Absolutely. Custom colored gemstone rings are one of our specialties. We can source a particular stone to your color, size and budget, then design the setting around it in 14-carat or 18-carat gold, from a single-stone cocktail ring to a gemstone-and-diamond design that is entirely your own.
Are gemstones tax-free in the Cayman Islands?
Yes. As with diamonds, the Cayman Islands charges no import duty and no sales tax on colored gemstone jewelry, so every piece is offered at its full pre-tax value.
