A wonderful impressive 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 Such large size with this quality is of course hard to find !! Measurements : 48 x 40 x 20 mm Weight 46 gr = 230 ct Excellent condition 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) 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
