Today great specimen : A stunning specimen of vibrant emerald-green dioptase crystals perfectly set on a quartz-rich matrix. Under UV light, the matrix reveals a striking red fluorescence, adding a rare and spectacular dimension to this piece. This combination of sharp dioptase crystals with glowing matrix makes it a highly desirable collector’s item. Sourced from the Tenke mines, this is an exceptional example of mineral beauty from the Democratic Republic of Congo. Very aesthetic specimen much better in person. I'm trying to show You specimens and crystals hand selected, not usual, beautiful and pricey. condition as on pictures. Color is very difficult to reproduce in the pictures. Some pictured specimens show slightly different shades that seen with a human eye. Generally in my opinion the colors in reality are slightly prettier.
