We are a family company who love opal and have loved sharing its beauty with the world for over 35 years of combined experience in opal mining, jewellery manufacture and online sales.

This rough opal was recently mined by us on the Olympic opal field of Coober Pedy Australia.

WEIGHT: 389 carats, 77.8 grams or 2 oz 10 dwt (troy) weighed dry.

These are medium to low yield pieces.

These stones should cut around 20-30 carats of solids and/or doublets but will yield much more if carved.
Use the ruler as your guide to size (INCHES)

We do not sell opal simulants of ANY sort. All of our opal is 100% guaranteed Natural Australian Opal.

The color variations in some photos are due to different light angles and distances. All of our auctions are photographed with macro settings under a halogen lamp. In all photo's the opal is immersed.

Please check the dimensions carefully as the opal will not be as big in your hand as it looks on your monitor! Please check the description carefully before bidding and view your purchased rough opal wet in sunlight or in a dark room with a direct light source ie: desk lamp, down light etc. (As photographed and practiced throughout the opal industry).
