Aquamarine Jewelry in Grand Cayman
The pale sea-blue of the Caribbean, durable enough for everyday rings, in 14-carat and 18-carat gold.
The Stone That Looks Like Seven Mile Beach
Aquamarine carries the pale sea-blue of the Caribbean, which is precisely why it sells so well on this island. It is a member of the beryl family, the same mineral group as emerald, but far cleaner: good aquamarine is typically eye-clean where emerald almost never is.
It is durable enough for everyday rings, which sets it apart from most pale coloured stones, and it comes in sizes large enough for a serious cocktail ring without the price becoming unreasonable.
Colour is the whole decision. Aquamarine runs from a barely-there tint to a deep sea blue, and price follows saturation closely. We set it in white metal to keep the blue cool, or in yellow gold when someone wants the contrast.
