Beautiful Ametrine from Bolivia, the Bi-Colored Gem

When Ametrine’s stones were first brought into our JOGS office in Los Angeles, California, we were shocked by their beautiful color and clarity.


Ametrine is a natural mixture of Amethyst and Citrine

Many visitors to our show have never seen the eye-catching stone, which is a naturally occurring mixture of purple Amethyst and Yellow Citrine. It’s usually faceted in an emerald cut, with a 50/50 split that showcases the often seamless transition between the stone’s two colors.

Ametrine is one of our long-time JOGS exhibitors. At the JOGS Show I met with Ariel Gamboa and Miguel Toranzo, who spoke to me about their business from Bolivia, a beautiful country located roughly in the middle of South America, and bordered by Peru, Brazil, Chile and Paraguay.

Although the company is named after the uniquely colored stone, they say that the stone’s real name is “Bolvianita”, because it hails from their home country of Bolivia. They work closely through all steps of the process, starting with buying the natural stones, and then work with cutters and artisans from Bolivia as their business.

Ariel says the company started as a hobby. He was looking for great stones in Bolivia, to cut and make jewelry from. He wanted to make a big collection – with thousands of stones and 50,000 pieces of handmade jewelry.

Some of these pieces were on display at our show, and he showed me everything from raw uncut Ametrine to finished pieces of all shapes and sizes.

During our interview he proudly held up a large piece of raw Ametrine, to show me the way the colors are displayed in the light. Even the name of the stone is a portmanteau of the stones Ame-thyst and Ci-trine, and both colors of quartz are easily visible even in the raw form of the stone.

To show me the difference in the way the two colors can meet in the stone, he held up a second pinwheeled version of the raw stone, which had a more even proportion of the two natural colors.

Although Ametrine stones are often cut in a 50/50 split to showcase the stark difference in color, Ariel had pieces that showcased other proportions, including some of my favorites like tear drop pendants that held a 30/70 mix of gold graduating into a light heather-purple.

His finished jewelry with larger pieces of Ametrine varies from piece to piece – often taking advantage of the stone’s composition.

He showed me large oval-shaped pendant that didn’t have the usual 50/50 split, but instead seemed to glow from within due to the location of the honey-colored Citrine in the stone.

In his booth he also had pendants of all shapes and size on display, set in both gold and silver.

The Ametrine rings were one of the most fascinating types of jewelry he carried, because of their simple settings. Due to the stone’s striking color composition, it does not require a complex setting to stand out. Many of Ametrine’s rings spotlighted the stone alone with no extra ornamentation. The Bolivian designs are a mix between modern and traditional styles.

During our interview, Ariel asked me what kind of stone was my favorite – and I had to reply it was the enchanting Ametrine stone that had come into our office months before the show. We’d never seen anything like it – we asked, is it fake? Is it synthetic? And we were shocked to find out it was a naturally occurring coloration called Ametrine.

Ariel showed me trays of his cut stones – although he keeps a few raw stones on hand, they’re mostly for display and to show customers where their stone comes from originally.

He also sells the stone’s two halves individually as brilliantly cut Amethyst and Citrine, and other quartzes and White Topaz, which is so clear it appears to be made of glass.
