Colored Gemstone Rings and Jewelry in Grand Cayman
Sapphires, emeralds, rubies, tanzanite and rare colored stones, set in 14-carat and 18-carat gold.
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.

EarringsOur 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.
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.
