i am surprised that nobody come out with a tension mounting for rb that you can...

[Dancing Fire]

rotate the stone 360 degrees. then you can view both hearts and arrows even after its set in a ring.

Maybe you're on to something.

A tension setting by definition holds the diamond by suspending it by two opposing sides held together by pressure, so the diamond couldn't be rotated... Setting the diamond in a bezel which would be a ring of metal around the diamond would enable the diamond to be flipped, but the bezel would interfere with the pattern as well... It's not that it hasn't been thought of, it just isn't practical.

I was thinking more like a little ratchet (the hand tool)were can you click and rotate it and still have enough tension to secure the diamond.

Niessing already has a ring very similar to this. It's the High Noon ring. They use colored synthetic gemstones (maybe the real ones are not strong enough?).

I hope the following leads to the rings I'm talking about (sorry if it doesn't work! check out niessing.com and search for high noon ring)

What about this?

 

[sumi]

tonysgeko, that is one of the Niessing rings. They also have another ring where the actual stone moves around (the High Noon ring). Let me try to figure out how to post a pic.

here's the high noon ring

Here's the Abakus ring. Not really what the original poster was talking about, but........

The ring with the square, rotating plate could be exactly what you'd need to see H&A's after a diamond was set. Have the diamond hammer set and burnished into a heavy plate that has a pin on opposite sides that will act as hinge pins when fed into the "tension" shank. You could make it click into up or down position easily enough so it would not simply rotate freely. The plate could be made to drop out from inside the ring and actually not require any tension. The finger would hold the stone and plate in the ring and you could examine the pavilion just by removing the plate and diamond so that you could view the hearts.

It isn't a big engineering problem. It is just something that has not been much requested. If someone wanted it, I am certain one of these guys with a CAD system could create for you. It would not be inexpensive because it would demand a degree of creativity and added time to get it just right.

A swivel diamond ring

Cool

 

[niceice]

Yes, yes, yes... But the challenge is still going to be doing it so that the pattern remains clear and visible, that is of course because we're assuming that the point is that you want to be able to see the pattern without distortion... The reason it probably hasn't been made by one of the diamond cutting firms that produces H&A diamonds? R&D $$$ gone to waste on a cool concept that only a few people will buy at the price needed to recover the design time / expense before everybody else knocks the concept off... That said, if you're in the mood to have the ring designed, you might knock on the door of Mark Morrell because he's as capable as they come.

Or the stone can be put in a tension set mounted along the girdle sideways. Hearts on one side, Arrows on the other. I've actually done such a thing, but holding two opposed stones simultaneously.
