Nick Kolias understands that opal is indeed a very difficult gemstone to value.
"Very few people truly understand what is involved in valuing this most unique and beutiful gemstone."
Nick is in the most privileged position of having worked with many of the industry's most experienced and knowledgable veterens, many of whom have either retired or passed away.
His expertise and knowledge is such that he has been commissioned to conduct specialist opal valuations, and prepare legal documentation for:
- The Australian Federal Police
- The Australian Tax Office
- The South Australian Museum
- The South Australian Police Department
- The South Australian Sheriff's Office
- The South Australian Public Trustee
From working closely with private collectors, Nick has seen some of the rarest and most collectable opals ever unearthed. Many of the most valuable and collectable opals are secured for private collections and never see the consumer market place.
Nick is available to assist you with any opal valuation queries, and can help in selecting and securing your ideal opal.
If you are visiting South Australia, Nick is available for private consultation.
