Understanding Gemstone Value
Buying expensive jewellery can be a tricky process when you don’t know how to identify the value or authenticity of the stones you’re purchasing.
Fake stones can be difficult to detect for the general public, and you will typically need a lot of experience in the field to be able to tell a real stone from a fake.
As such, it’s good to understand the key terms used in the jewellery industry to gage differences in value and make.
For example, lab-created Opals or cheaper alternatives are commonly known as Doublets and Triplets. Doublets and Triplets do not have the same strict standards compared to solid opals and are considered less valuable, but it is generally sold for the same value as solid opal.
Opal is difficult to value and the evaluation process is even more complicated than diamonds.
This classification system considers the colour, pattern, brightness, shape, inclusion, body tone, origin and whether it is a natural opal versus a treated one.
Treated Opals can sometimes be sold as natural (more valuable), so it's important to be able to tell the difference between the two.
Is My Opal Real Or Fake?
It's essential to consider these key factors when examining an opal for authenticity...
Examine the Pattern:
Synthetics typically look ‘too perfect’ in terms of pattern, colour, and direction. A real Opal should have less systematic patterns and more inconsistencies in brightness and colour throughout.
Look out for ‘columnar’ or ‘snake-skin’ texture/pattern: Turn the opal on its side and look through it. If you see straight column-like patterns, then the opal is likely synthetic.
