St. Clair, Mich.– The Yellow Emerald Mining Company, a Michigan-based mining company and distributor of golden-hued beryls, recently announced the introduction of “Emeryl Jewelstone,” a yellow-colored beryl with traces of green mined in Brazil.

The company said it presented the Emeryl Jewelstone, a name it has trademarked, at the World of Gems conference, held Oct. 13 and 14 in Rosemont, Ill.

It is described as yellow to gold in color with “strong flashes” of green and a high clarity. It is a natural beryl, with chemical properties similar to green emeralds, another beryl. Green emeralds have traces of chromium or vanadium, which produces their hue. Aquamarine, another beryl, has traces of ferric iron that give it its hue.

The Emeryl Jewelstone has both ferrous iron and chromium, so its color varies in different lighting, according to the Yellow Emerald. Sometimes, the gemstone appears more yellow, other times more gold and, sometimes, it shows hints of green.

It was discovered in the Minas Gerais region of Brazil in one mountain. All the stones are hand-cut in the city of Governador Valadares and have at least 70 facets.

The gemstone varies in size from 0.75 to 6 carats and is priced at retail between $150 to $600 per carat, depending on quality, grade and size.

Yellow Emerald said that Emeryl Jewelstone gemstones come with an unconditional two-year warranty.

“Production has been very limited in the last three years setting up the mine, but now we have the people and equipment in place for a medium-scale production, making more gemstones available to independent jewelers around the country to offer their customers something very different, new and exciting, not to mention affordable,” said Patrick Coughlin, CEO and founder of Yellow Emerald.
