Item details

Each purchase is for 1 (one) Andamooka opal tile, measuring approximately 2.5 x 2.5 cm x 0.5 cm thick, chosen randomly from a lot. The picture shows some examples of the tiles.

The Andamooka region has many fine opals, and one type is matrix opal. The opal is in the cavities of a limestone host rock. This is called matrix opal. The limestone is then cooked in a sugar solution to turn the limestone black, which allows for the color to show up.

Each purchase is for one tile made from Andamooka matrix opal. Each specimen is a well prepared piece and the opal colors themselves are natural. The specimen has a thin coating of polymer casting resin on top which helps show off the colors, the back is uncoated.

The tiles measures approximately 25 x 25 x 5 millimeters and usually weighs 30-40 carats.

I also have other individual pieces in my shop.
