DVCollector Bedrock of the Community United States 10045 Posts	Posted 09/16/2012 11:18 pm Quote: It's a very intricate design for someone to fashion that from sterling. Yes--it would be for lost-wax or soldering, but I'm guessing it's mass-produced, as most settings are...in that faraway land where most of our retail stuff is made. Not a bad idea to try the UV light. Pink CZ will look whitish-blue. Kunzite and pink sapphire will glow a bright red. Bright blue fluorescence is often seen on diamonds.

sel_69l Bedrock of the Community Australia 21788 Posts	Posted 09/18/2012 01:12 am Diamonds are easily distingushed from CZ CZ is a strong insulator of both heat and electricity, diamond is a conductor of these, except for one rare class of diamond which also is an electrical insulator. The test is simple. A pair of pointed probes are contacted at opposite sides of the stone to be tested, and conductance (electrical and heat) are read off a scale. The stone does not even have to be taken out of the setting. Report this Post to the Staff
