13.8 Carats, Natural Australian Opal Stone, In The Rough, Coober Pedy Large and Bright. This has been faced and has no risk. Its large full of colour 21x21x5mm. Has a crack on the side and if you cut it you will make small gem from the off cut. It shines very bright and there is very little weight you will lose here. Awesome stone being sold fr less because i got it cheap so you get it cheap as well.
