I was in the wholesale gemstone business for years and LOVED it! My first job was working for the foremost sapphire cutter (ok, lapidary!)in the world. Back then we weren''t so fussy about the title!...Anyway, he was the most respected sapphire dude in the Far East to our West! To this day, decades later, I can spot one of his stones a mile away( usually in an auction house brochure/or fine jewelry retailers'' ads, or in a adds for BIG sapphires! ..How many good 20 to 40 carat sapphires are out there anyway? Its so neat to find a place where I can see and hear what "privates" (as we wholesalers, called y''all buyers back then)I used to wonder who the hell WORE this stuff??? ha ha...Just want to put something out there... each colored stone requires different facets to bring it up to its perfect state of... beauty/perfection...there is a science, but, also an ART to the cut...I see here, that some are caught up in the mechanical side of how and where facets are put...NO! NO! NO!...The best stones that came out of our office sometimes started off as 40 carat ugly buggers and ended up as 3 carat GEMS!!!...its not about a formula of faceting (like diamonds), its about where the lapidary( the artist)sees the color and then places those sometimes, strange facets...its a HUGE risk,and a great and stressful ART but when it works, WOW!!!!...''do we keep the weight and sell at per carat weight with a slight profit, or do we lose the weight and make a "GEM" quality stone that can double or triple at price and rarity because it is now PERFECT,there is a risk factor there (what if the stone breaks on the wheel, or the decision was wrong??? (it is , after all, bidness!) The temptation is hard to deal with...it disturbs me, that people seem to think that, as with diamonds, choosing where a facet goes is mathematical, not artful...Anyway, I am just babbling right now, because I am so happy to find a place where the fine art of gemstones can be discussed!! And, well...I have a place to babble!! and it has been years since I have been with people that appreciate my first professional love!
