I have a 16.9ct emerald to value and was wanting to see what you Poly folks thought. It is pale, slightly bluish green, due to chromium, just enough to still be called an emerald. It is quite clean for a type 3 stone but does appear to be clarity enhanced. It would probably grade as "minor" clarity enhancement. It is peppered with tiny pyrite crystals, as well as 3-phase inclusions. My understanding is that these inclusions would suggest the Chivor area of Colombia as its origin. What would you value it at?
Read on here a couple of months back about an old euro Moissanite. Never saw one until two days ago. Polypal sent me a 3 carat old euro. HUGE culet, not that well cut. Large brooded girdle. Very typical of an old Euro.
1. Cool old charms, with moving parts, lights that light up etc
2. Filigree old rings
3. Weird stuff, almost too weird to explain, creates curiosity
4. Anything with a cool signature (Tiffany, Cartier, VCA…)
1. Waterfall clusters
2. Crosses, unless small and white gold
3. Stampata (stampato) super hollow gold necklaces or bracelets
4. Yellow gold invisible set rings, unless very secure channel so it can be sized
Recently, ABC News reported a jeweler getting busted for selling a CE diamond but not properly disclosing the treatment to the customer. It’s interesting to see how some salespeople sell a Clarity Enhanced stone but don’t explain what it is.

Tell me more about CNC milling? I’m interested in alternative ways for our watchmaker (who can work wonders!) to make gears and multi-toothed wheels for pocket and wrist watches.

We put a gent’s Lapis ring in the cleaner, it came out whitish. Can it be re-polished or treated to bring back the dark blue?

How do I grade/appraise clarity enhanced diamonds?
Kays is coming to our center. They are a TOTALLY different store than us, but I was worried about the potential loss of customers. Any ideas?
Fake rough is being replicated so well, that it's been hard for even experts to figure out if they are real or not. There are certain naturals on the rough which make it easier to identify them. Was trying to find out if there are any references out there or tips to help differentiate between the two.
