Time for transparency?

Recently I had a discussion with a gemmologist who is also a gem supplier and predominantly supplies heat treated sapphires to the Australian market. I’ll try not give you clues of who this person is. 

He/ She says that when he/ she sells a heat treated sapphire to a customer he/ she does not disclose that the stone has been heated unless the customer enquires. His/ Her argument is that as no external elements have been added in the process of heat treatment, the stone is 100% natural and that they have simply sped up the heating process that would have otherwise occurred naturally under the Earth’s surface. He/ She proceeds to say that Australian customers do not tend to query whether the sapphire has been treated, but international customers such as in Europe and US do query this often. 

I believe this has more to do with lack of customer awareness here in Australia, whereas European and US customers are a lot more educated about gemstone enhancements. 

I feel this is a bias opinion from a seller who supplies heated sapphires. Whilst I appreciate that heat treatment has assisted vastly to maintain reasonable prices by increasing sapphire supply in the market, it is still an enhancement to the natural stone. There is no guarantee that a heated sapphire would have the same performance if it was left underground for many thousand years more. One of the greatest fascination of gemstones is their rarity. Evidently fine quality unheated sapphires are rarer than enhanced sapphires.

Customers need to be aware of what they are purchasing. 

In my opinion, if the seller is aware of any kind of enhancement to the gemstone it should be disclosed regardless. The customer can then proceed to ask more questions. This would be a great opportunity for the seller to educate the customer about the difference between traditional heat treatment and other treatment methods. 

We used to deal with heated sapphires ourselves, but we disclosed all information we were aware of. I think it is important to disclose known enhancements of a gemstone and educate customers in order to maintain a trustworthy industry. 

This is such a dividing topic, your opinion is greatly appreciated.
