Would you Put This Stone in a Tension Setting?

[Andelain]

Hi again.

I've got a project in the pipeline that involves putting a stone in a setting very similar to this..

and this stone here http://www.goodoldgold.com/diamond/7379/ , would be perfect for it. My only concern is the inclusion. Do you think it would be at more risk than a stone without that inclusion? Yes, I asked GOG the same question, but Jon is away for a few weeks so I'd like your opinions if you would, please.

a true tension I would say NO I would not put that diamond in a TRUE tension, however your setting has an undersupport bar so its not a Pressured Tension setting, and I would think it ok if channel set in, I mean, it seems even if you put it in a four prong setting all the girdle is exposed for greater risk of chipping. however, with your setting it looks like its wide enough to "protect" the inclusion side instead of thin shank. This is just my consumer opinion who loves anything tension/ bar set/ channel setting. I'd be interested to hear the expert/appraiser chime in though.

Looks possible to angled the stone in the setting such that even in a true tension setting, the setting is not really coming in contact with the feathers but the feathers are still protected by the setting.

For a true tension ring, the designer first needs to approve the stone. That's what I was told at Stuart Moore when I was looking at Niessings. If they feel it's high risk, they won't set it. They also said that generally higher clarity diamonds are used for tension, above SI.
But I guess it would depend on the type and placement of the inclusion.

So if you're buying this stone specifically for a tension setting, I'd make sure you can return it if it can't be done.

Btw, which setting are you looking at?

(I'm doing a tension ring too as soon as I decide on a round or asscher).

StoneCold, I'm not sure how what you described could happen? How would I not have the tension on the inclusion, yet be able to protect it? Thanks

That's something I didn't know, I'll have to ask about it before I buy the stone. It's not a true tension set, I guess I could call it a single stone channel set. I'd want the inclusion as hidden as possible, of course.

Unfortunately I can't show you a pic of the setting, there are none yet. Like the pendant in my avatar did 6 months ago, this one exists only in my mind right now.

I had a diamond set into a tension setting by PUR in Germany.
They wouldn't set anything under an VS2 - or any feathers too close to the girdle. and they didn't
like "thin" girdles either... They were super picky!!!

Perhaps, when setting the stone, they might position the feather to be right at the "exit" of where the
stone and metal are in contact to prevent stressing the feather while being protected by the proximity of
the metal...
