we have had 2 sapphires in the last 3 years go south on us. one was
a very pretty celon blue in color, our cost, was over $3000.00.
was in a ring, was sized with out protection to stone, hey its a
sapphire. was air cooled to where you could place your finger on
stone, but still warm and dunked in citric acid, and the sapphire
came out looking like a quenched cz?? internal cracks galore.
needless to say the boss was not happy, fast forward a cpl years.
this is a dark blue large sapphire clear. was in a pair of
earrings, surrounded by diamonds in a basket mounting. cut the
mounting apart to put into ring for customer and the heat involved
here was not as direct as tipping, soldering a heat to a mounting
kind of heat. this stone was not quenched, was air cooled and it
looked like a crazed cz just as first one did.
are these stones treated?? any would be very helpful, as
of now any expensive stones are being treated like a emerald, no
