Chromia Starbrite Cut Ametrine and Diamond Ring in 18K

Amethyst and citrine, the purple and yellow gem varieties of quartz, also sometimes combine into the surprising two-tone gem called ametrine. The Anahi Mine in Bolivia is the major world producer of ametrine. The mine first became famous in the seventeenth century when a Spanish conquistador received it as a dowry when he married a princess from the local Ayoreos people named Anahi. Ametrine was introduced to Europe through the conquistador's gifts to the Spanish queen. Wearing ametrine is like gazing on an eternal garden, filled with happy pansies and elegant irises.

Creating 18K white gold is jeweler’s alchemy. To make luxurious 18K white gold, 75% pure golden yellow gold is alloyed with 25% white metals, usually silver, zinc, or palladium. These metals also increase its durability and hardness. To get that bright white shine, most 18K white gold jewelry is plated with rhodium, a platinum group metal.

With exceptional gems, finely crafted 18 karat gold, and thoughtful design, every piece of Chromia jewelry sets the standard for heirloom quality.

Spotlighting rare gems sourced directly from the mine to the cutter and the workshop, Chromia comes from the Latin for “all colors”.
