Re: A Green Diamond with uncertain color origin

Something that's really important to note is that diamonds are treated in rough form. 'Following the rough' through the cutting process does not guarantee it was treated before that. There are several documented cases of GIA getting treated rough of colors with discernible treatment. Fully saturated...

Re: Another emerald question

Something you could do, if interested, is to train yourself to identify good emeralds and their treatment. Emeralds cannot hide their treatment so it's pretty easy to find out an emerald's quality by looking closely with a loupe, even if it's mounted in a ring. Ron Ringsrud has a great book that tea...

Re: Another emerald question

I'd say 2K is a good rough number for something in that range. The challenge is going to be finding something that small that is only oiled. Most emeralds nowadays are treated with more durable materials and some retailers will just state it's oiled as a generalization for treatment. Chrono's right,...

Re: will $4k buy me a nice Colombian Emerald?

Typically for vendors that import stones directly from source for wholesale clients with professional buyers they will only 'paper' a stone to justify a significantly higher price. Emerald prices are based on the assumption of moderate treatment typically, so it's a little rarer to have 'paper' atta...

Re: will $4k buy me a nice Colombian Emerald?

A 'flawless' emerald just has a lower amount of internal fractures that are visible to the naked eye. Under magnification, emeralds have textures and inclusions, and those are the source of their velvety glow, somewhat similar to Kashmir Sapphires. This texture makes high quality emeralds 'lifeless...

Re: will $4k buy me a nice Colombian Emerald?

It depends on the size, and price varies substantially with the quality of the gem. At 1 carat, $4,000 could get you a Colombian Emerald with moderate treatment, maybe even minor on a good day, and a close to ideal color. It would be a very beautiful stone with the treatment barely visible under a l...

Re: Record Emerald Sale in Geneva

It's important to state that high quality emeralds do not photograph accurately. In fact, if a stone photographs well it's probably a little too glassy or not completely saturated. You have to see them in person to appreciate them. Not sure if it has the 'drop of oil either'. I'd love to see the sto...

Re: Record Emerald Sale in Geneva

In the very high end market, internationally, some clients lean toward Gubelin. That report in itself is almost 1,000 USD. They are very highly respected for large value stones. Just in case someone doubted them, they provided two other reports. lol.

Totally natural. No oil, no traces of oils, polymers, resins or anything else. Very, very rare.

Re: Record Emerald Sale in Geneva

Lol, you guys are cute. Definitely not a stupid question. The main reason is it's documented (by three labs no less) as untreated. It's extremely rare to find an emerald of a perfect color (hard to see in the photos) and excellent clarity (for an emerald) that is untreated.

Re: How to set an oval emerald?

The last two settings that you've shown are the best approach to setting an emerald. This is because the petals of the flower are extending above the edges of the stone and would help to reduce impacts to the top of the stone.

Sure, a crystal emerald is a lighter tone and saturation emerald that is bright and very clean internally.

Congrats on a very beautiful crystal emerald! I would also tend to point you in the direction of a prong setting.

Re: Do Emeralds change color under "blacklights"?

I guess we'll just agree to disagree. I called GIA and spoke to the lab, and she read the same paragraph from the book to me that she probably read to you.

LD, yours responds so lightly to UV it could be treatment, impurities (since it's heavily included), etc, especially since your other emeralds don't react.
