How To Identify Fake Ethiopian Opal

The popularity of Ethiopian Opals has exploded in the last few years. Buyers always need to be on the look out and do their best at knowing how to identify fake Ethiopian Opal.

So many shops across the world now carry Ethiopian Opal and sell them to the general public at a price point that is lower than Australian Opals. Many buyers do not have experience with this type of Opal and many of them think they are being sold synthetic or fake opals. We will try to explain the best ways on how to identify fake Ethiopian Opal below.

  1. Ethiopian Opals are mostly Hydrophane and do have waxy different feel compared to other Opals and this can confuse new opal buyers. It is fine if the Opal feels like this.
  2. Always source your Ethiopian Opal from a reputable seller. We cannot stress this enough. A good seller will talk you through your potential purchase and even if you are not happy with it, they should always be willing to swap the Opal for a different one or discuss a refund.
  3. Try your best to educate yourself before you buy. The more you know what a real Ethiopian Opal looks like the easier it will be to buy a real Opal.
  4. If you can ask the advice of a Gemologist to help you or an Ethiopian Opal expert.
  5. Look closely at the pattern in the Ethiopian Opal. Fake or synthetic Ethiopian Opal will usually be ‘too perfect’ and look man made. A natural opal will have less systematic patterns. They will also sometimes have a difference of colour or brightness across the Opal.
  6. Look for what gemologists call ‘Columnar’ structure or ‘snake skin’ pattern. This is the sign of a fake Ethiopian Opal.
  7. Look at the shape of the Ethiopian Opal, even a polished natural Opal will not be perfectly round or oval. Many times fake Ethiopian Opal will be perfectly round in shape.

Below are examples of Natural Ethiopian Opals, note all the different patterns.
