I had this conversation with a seller I had contacted about buying a ruby.
Me Are all of your rubies fissure filled?
Seller-90% of all rubies on the market today are fissure filled..most of my rubies are fissure filled however mine are not lead glass filled ,mine are treated with high grade non lead bearing optical glass.Additionally fissure filled rubies i carry have a content no more than 1.8% which is really low.Essentially the glass heals natural imperfections in the stone and using the high grade optical glass it also improves light refraction within the ruby giving it a significant increase in depth of color and the "glow" associated with high grade rubies..These are not glass rubies or fake they are just heated with an optical grade glass powder around the rough to heal imperfections then they are cooled and faceted...the market price for these rubies are HIGH and in my opinion and that of several other gemologists,we feel that the treatment does nothing to lower the value of the gem,we find the value is increased due to the beauty and durability of these gems.
Me Thanks for the info I''ve been taught to be leery of treatment just on principal. So I thought that fissure filling was really bad.
Seller- There are people who ride one side of the fence or the other on the subject of gemstone treatments. I myself ,surprisingly am a purist, which means I prefer untreated gemstones,however buying rubies I found that it was next to impossible to find one of any quality that was not fissure filled.I also found that everywhere i looked even on ebay the rubies were all fissure filled...if you want a good ruby you just cant get an untreated one of decent quality unless it is fissure filled..if you actually find one it will be RARE and it will also be prohibitively expensive..i learned to adapt and i found a guy to use only pure high grade optical glass to heat and facet mine..usually I test the content of each ruby and if it goes over 1.8% content of glass I toss it in the fish tank.
thoughts? this newbie needs advice
