Ouro Verde Quartz Gemstone
Sparkling in a refreshing lemon-lime color, Ouro Verde Quartz is a unique gem that'll find a special place in your collection.
While there are many exciting yellow and green gems on the market, few combine these two hues in a fascinating and captivating combination! Ouro Verde Quartz is one such gem, introducing a rich yellow body with the smallest hint of green. The combined effect is life-affirming, just like the first blade of grass after winter.
Ouro Verde Quartz Quality Factors
The Minas Gerais region of Brazil is world-famous for the quality of its quartz. Specimens tend to be eye-clean, making this rock crystal ideal in a variety of applications. Ouro Verde Quartz is finished to eye-clean clarity, the best clarity grade that a colored gemstone receives.
Ouro Verde Quartz Treatment and Care
Ouro Verde Quartz is irradiated with cobalt 60 at very low levels to induce the initial color. Initially, stones will appear black or brown in color. Once irradiation is complete, the gems will be heated to about 650-degrees Fahrenheit to remove the black or brown and induce the final lovely lemon-lime color. A device similar to a household toaster oven is utilized in this process, as it allows the stones to be monitored and removed once the desired level of color is reached. Care must be taken through the entire process, as heating the material for too long can ruin it, creating a gemstone with a milky appearance. Once complete, the treatment is very stable, though stones should not be exposed to heat or light for extended periods of time, as this may affect the color.
It's a jewel that requires simple care. Wash it in a solution of luke-warm water and mild dishwashing soap. Scrub with a soft bristle brush. Dry with a soft cloth. That's it!
Consider Ouro Verde Quartz if you love gemstones such as citrine, sphene, peridot, or chartreuse quartz. The crisp hues of this jewel make an excellent addition to your collection.
What Does Ouro Verde Quartz Mean?
• In Portuguese, ouro verde means 'green gold,' and is a direct reference to the gem's pleasing citrus color. The word quartz has roots in German from the sixteenth century, though its exact origins are not known. Popular theories suggest it was a reference to a particular kind of ore that crossed veins of material found in silver mining.
While well-known around the globe for the quality of its quartz, Ouro Verde Quartz only comes from one location in Brazil. The Boca Rica Mine of Minas Gerais produces this unique green tinged golden gem.
Where Does Ouro Verde Quartz Form?
The Boca Rica Mine is located within the Eastern Brazilian Pegmatite Province, a region of the country which comprises the majority of Minas Gerais, in addition to portions of Bahia, Espírito Santo and Rio de Janeiro. These pegmatites are vital to the gem and mineral industry of the country, as these pegmatites have been formed under some of the most ideal conditions in the entire world, resulting in the earthly wealth that the country enjoys. Pegmatites form during the final stages of magma's crystallization. This allows exceptionally large crystals to form, leading to the impressive quartz specimens found across the entire state of Minas Gerais.
Historically, Boca Rica is known for its aquamarine. However, the mine has not produced any notable material since about 2010. Ouro Verde Quartz is singly sourced from this particular location.
