A wonderful precious OPAL from Ethiopia, showing lots of different colors of fires ! I carefully chose it years ago among hundreds of similar pieces from an opal dealer, it comes from my own collection Measurements : 35 x 26 x 22 mm Weight 18 gr = 90 ct Excellent condition ** WATCH a 1 min VIDEO to see this opal perfectly (youtube link below) : https://youtu.be/1vn1jozy2vs IMPORTANT : I am a reputable art dealer with a high level minerals collection I don't use photoshop to improve the color, i hide nothing, you see all the sides !! WHAT YOU SEE IS WHAT YOU GET !! The photos have been taken the evening (artificial light) - This opal was NOT wet when i took photos (lots of sellers used to put opals in water to improve the colors...that is cheating !) It needs good light (daylight or artificial light) to see opals fires and to display them, weak light means weak fires ! More the light is strong, more you will see colors and fires !! This advice is for ALL opals !! Acrylic base not included
