A 15.7ct Opal Rub Parcel of 5 Stones

5 nice 15.7ct opal rubs This parcel contains mostly multi coloured stones. The oval has some bright red/orange present. I just noticed this rub has a crack in the surface but it will still cut a 3 carat stone. The round pinfire pattern stone mostly green/orange and is on grey potch. Four of these rubs are very similar in brightness and are on black potch. The brilliant red/orange is slightly directional but has some real penetrating flashes as they are rotated. the oval shaped rub is the brightest in the parcel. These rubs will suit pendants or ring settings. More nice material from the Grawin opal field.
