If you would like to find out the value of your opal bring it to Australian Opal Cutters! We have extensive experience in cutting opals for over 35 years and use industry standard program called "Smart Chart" to value any natural Opals with a detailed and systematic approach.
This "industry leading" program assesses the 13 characteristics of an Opal to determine its value. These characteristics include:
Variety, Body Tones, Brightness, Transparency, Colour, Hue, Outline, Profile, Pattern, Display, Distribution, Inclusions and Weight.
We recommend having your opals valued every few years as fine quality opal will increase in value each year as much as 15%, so let us tell you what its worth today.
Written Valuation (or Verbal) Valuations are available for as little as $25! (For each Opal or a piece of jewellery)
Following are just a few examples of categories that need to be assessed in order to finalize the value:
Colour: is best when multidirectional. You should be able to see different colours from variety of angles.
Brightness: intense, brilliant colour is more valuable. High quality opal will show you colour without direct light
Pattern: large blocks of colour are preferred. Harlequin pattern is the most valuable.
So BEWARE anyone who tries to tell you what your Opal is worth without first assessing the 13 characteristics of the Opal.
Opal is in the TOP 10 Most Valuable Gemstones in the World!, so be sure to ask your valuer "Do you use Smart Chart?" or find out which valuation program your valuer has used to assess value, because if it is just an "opinion" it is basically not worth considering!
For every 130 million carats of diamond produced only 1 million carats (or 200kg) of opal is mined. And from this rough the loss factor in cutting can be as high as 95% (In black opal).
You may have heard that “Tanzanite is 1000 x rarer than diamond”. This is suggested because there are 100 miles of tanzanite mines worldwide, and when compared to the 100,000 miles of diamond mines worldwide “Tanzanite is 1000 x rarer than diamond”. As there is only 20 square miles of black opal mining, black opal is actually 5000 x rarer than diamond. Opal is an extremely precious gem. Black opal is possibly 130 times rarer than diamond!
Opal is a diminishing resource and there is anecdotal evidence that suggests an increase of up to 25% per annum in boulder opal prices and 15% per annum increases in white, crystal and black opal. The value of an opal purchase is established when you purchase it as, compared to diamond, ALL opals are sold for much less than their true worth.
So please contact Australian Opal Cutters to find out the TRUE value of your Opal!
