This listing is for a very unusual spiderweb turquoise. This is a very large oval and the dimensions are 24 mm by 44 mm and is 4 mm deep. The weight of this turquoise is 37 carats. This stone is not backed and is polished on both sides.
I've had the stone in my collection for a number of years and can't recall the origin of the material. The color is most unusual and the web pattern is beautiful. This stone is totally unique and reminds me so much dinosaur bone.
This stone would certainly qualify as a collector gem, in my opinion. The uniqueness of this material deserves to be in a nice setting. Since the back is finished you could easily be a wire wrap setting.
