Sapphire & Ruby heat treatment enhancement

 

Gemstones are sometimes enhanced for their color or clarity since ancient times, especially relevant is this with rubies and sapphires different processes either by techniques or human are possible.

Basically there is nothing to say against it as long as the seller tells this to the customer when selling that gem and the price is accordingly. The problem usually is, they don’t tell this to the customer but ask high prices similar to an excellent none treated.

Now, if the gem would stay like this forever as it is with originals that also would still be somehow acceptable, but it won’t stay like this and that’s cheating. After usually around 3 years the gem deteriorates and what is left is junk one has been bought for lots of money.

Here is how it's done

Conventional processing is to throw the stone into an “oven” as it was done already in ancient times.

Glass filled is a new treatment to pop up ugly sapphire and ruby stones; this is a newer process because it needs quite some pressure which was not available before. Usually this processing is done with African gems since they lack the basic quality Burmese gems have.

Heat treatment with Beryllium, this is a very new treatment where the stones are heated together with beryllium for a better color. This works best with yellow and orange sapphires.

Bangkok and Chanthaburi ruby trade

This are the main places in Asia notorious for selling these treated gems are , there are honest sellers who tell the true and other who don’t tell and lie, in general it needs to ask make a statement and have it signed. This won’t help when the gems are sold “over the counter” at the street side as it is normal in Chanthaburi because this dealers are there today and gone tomorrow. Actually at Chanthaburi when dealing with gems “over the counter” a mediator is sitting in between to keep cheating at bay. Ruby and sapphire mining in Madagascar currently only second to Myanmar is done often by Thai companies who invested in mines there, they import the gem to Thailand and sell them here. At Chanthaburi every day lots of people from south Asia and China come to buy the stones.
