This beautiful Uruguayan Amethyst weighs in at 187 grams. The region it comes from in Uruguay can have upwards of 5000 different tones to what we once thought of a just a purple Amethyst. Several factors go into pricing an Amethyst. Color still being one of the top contributors, though rock and gemstone collectors are now beginning to seak out other options such as pink, grey, black, red clear lavendar and so many others. Other characteristics to price may include weight, crystal formation, size, if something else is growing within it, and formation or shape. Let me know if you have further questions, or if you desire something special. I have availability for orders.
