Jadeite vs turquiose in earring design


#1

I have been having problems with an earring design I make with a 6 mm
in diameter turquoise disc being riveted onto a piece of copper. The
new turquoise I have is breaking on each rivet. Would jadeite be
harder? I am not hammering on the turquoise ā€“ am actually making the
rivet for the turquoise side first, then hammering the other side,
being careful not to hit the turquoise. Also, if I got jadeite discs
could I easily drill out the hole to enlarge it? Thanks for your
help.

Jadeite is much harder than turquoise and a bit tougher, but can
still be on the brittle side. Try using hollow rivets. You can form a
solid head at the front of the tube so it has the appearance of a
solid rivet.

Jadeite is second toughest stone of all It is only
exceeded by nephrite. If jadeite exhibit brittleness, it is because
it has been treated. It is usually junk quality with is bleached
first and than treated with a dye. When buying jadeite get the
dealer to guaranty in writing that jadeite is of type A, and stay
away from all other types.

Jade is a very tough material, not brittle. I knew a gentleman who
cabbed jade and he tested the stone after cutting by bouncing the
cab on the cement floor of his studio. As with any stone, if it has a
flaw in the structure, it might break, but otherwise, it is a tough
and durable stone. It has been used for tools and weapons.

Thanks, Leonid.

Over the years Iā€™d seen a few jadeite Pis crack from dropping, so I
assumed it was a brittleness inherent in the stone generally. Thanks
for the correction.
