Wholesale price on chrome diopside?

[valeria101]

Is this inquiry about one large green stone only? Or a whole load of Diopside?

For the first version, maybe Diopside is not the answer after all. This is what this post is about:


Out of curiosity, how could this be cut (even an outlandish form) so that one can have a large piece that is not dark? Maybe...

I have seen larger rough in the past, but had no use for it and didn''t pay attention because of the darkness. Besides, with green tourmaline around, diopside didn''t ring the bell much.

There is a ~30 carat piece among these (LINK to rough list)


And there are the darker green garnets:

still a bargain relative to a clean emerald of equal size (what isn''t, really....).



Just as a side note, would a 10 carat piece of uncut Diopside do any good? Here''s one for $200. I am not sure this is the right picture form the site. The return policy works and cold help verify the claim that this is clean and cuttable.

There should be more, but if the material is not so desirable that every seller would make a point of offering it, you might have to ask them.

Ana,

I am referring to one large stone in what is known as Imperial Diopside. I am not talking about a lot. As far as the larger rough goes, from what I understand, you can loose 90% of it to get a larger clean stone. So from what I have heard, if I want a 5 carat + rock, if you have a 50+ carat piece of rough, you just might get it.

Here is a link to what I am refering to as far as Imperial (which is still chrome) for reference..

If that is what a matched pair of 5 mm stones lists for (and I know there isn''t all that much gold to them), I would hate to see what a big honking rock lists for.

I did look at their rough though before. I wonder how much loss there would be with that outside fracture. It says VVS, but I question that. I will have to keep that in mind though. If you cut that thing, and you ended up with half with any luck, and clean....hmmm. Either way it''s still a bargain compared to an emerald. LOL

PS I''ll post something later for ya..

Maurice,

Hope there''s no permanent damage. I got hydrochloric acid in my eye once when testing gold so I can really sympathize.

Hm... that sounds drastic. I would not generalize - especially since only portions of rough pieces are usually clean enough to facet. So, 10% recovery is before or after the deadwood is cut off, etc. Shape counts etc. So each case is to be taken for what it is, for better or worse. This one? No idea. A cuter would know and perhaps the seller could give you some idea - if they have a return policy, I don''t think they like making use of it.

Here''s another LINK

and another
I doubt prices can be extrapolated from half carat to 10 carat like that. $200 some would charge for the settings! If this is relatively expensive, it does not mean that the price is likely elsewhere either or that the looks of the material is unmatched, especially if the material is unusual and attractive some shops may be willing to bet more on it than others.
Just a thought.




It says VVS, but I question that.

Yeah... that probably means ''eye clean''. So many use the wording like that, I wouldn''t worry.




I will have to keep that in mind though. If you cut that thing, and you ended up with half ( third ? ) with any luck, and clean....hmmm. Either way it''s still a bargain compared to an emerald. LOL

... and a little pleasant thing to do after all

It would be safer to look of cut one,s of course. ANd there should be more desirable uncut pieces out there too. It would take asking around, apparently.


Hope to see your stone posted!

Hi Ana.

What I was referring to with the rough is based on what I have read. They say you have to work through 90% of it to get a really large stone due to the inclusions. However, they simply don''t just chuck that 90%. From what I have read, they take that and make cleaner accent stones out of it. That might explain why you can''t get a really big stone most of the time, and you can find smaller cleaner ones.

I did look at the links you gave me. The one has some really good prices for the cut stones that are clean. The rough on the other stuff looks really jadey. I was a little suprised to see $83 a carat for that rough. Thanks again for the info though. It''s always good to know these things.
