What Are The Ruby Treatments?
A treated Ruby is not a bad thing. Less than 1% off all Rubies that are recovered from the ground actually make it to the market without any treatment. These are the most precious and value Rubies available. If they did not treat Ruby gemstones, 99% of the Ruby would never make it to the market. That means the average person may never see a Ruby in their whole life if it was not for treatments.
Untreated Ruby
By far the rarest and most valuable Ruby gemstone. These stones ave been mined out of the ground, cut and polished and presented to the market. No other process apart from cutting and polishing has been performed on these Rubies.
