check all stones before cleaning. If you find any that are loose,
show your customer, and sell them a repair
You're right and I do that. I have a surgical looking probe and mark
loose stones with a sharpie. My bench is right in view of the
customer. Presentation is everything.
I've found that probing will only show stones that rock. Sometimes
pave' stones will probe as tight but the stones may actually just be
pressed into the hole with the beads not really holding, an 80lb shot
of steam from the back can blast it out.
Yesterday I offered to security check a lady's diamond and sapphire
bar set eternity band while we discussed whatever it was we were
discussing, "Why don't you let me check your ring". She said, "Oh no
that's OK, the place where I bought it just had to redo it, the
stones fell out". I replied."In that case Ma'am, lowers voice why
don't you let me check your ring". She was aghast when it turned out
every single stone rocked noticeably. So the jeweler that did it will
tighten it and they will loosen up again because the stones were set
near the top of the bars, unsupported by the bearing, girdles
protruding too far beyond the sides of the mounting. (large stones
in platinum, think leverage).
So, will I get the remount job when she becomes totally frustrated?
It's happened before.
I know, its a bit mercenary but ya gotta make a living.
