Will a 5x5 princess cut setting work for a 4.8mm cushion?

[stargurl78]

I recently purchased a spinel cushion-cut stone that measures 4.8 x 4.8 mm. I found a reasonably priced setting that fits a 5x5 mm princess cut. Do you think this setting will work for my stone or will I have to have it customized?

Stargurl, my first instinct is to say yes it would, but does the 5x5 setting have chevron prongs or traditional prongs? Also, is your cushion considered to be more "pillowy", or does it have straight sides?

Typically, with prong settings, you have a bit of leeway (~.5mm either way), so you should be ok, but if it's a halo or the basket is shaped for a different stone, you may have some issues with seeing around the stone.

Do you have pics of both the stone and the setting?

Lauren, thank you so much for the info. I have attached the links for the stone (last one on the page) and the setting I am considering. But based on what you have said, it sounds like it should work. Let me know what you think:

Pretty spinel! I would email lan.bo4 just to be sure, but based on the pic of both the setting and the cushion, it should work. Good luck!

This is a great idea. I love the stone you picked out.

But I'm not sure if it will fit in the setting. The sides billow and the corners of your cushion are rounded. This means that the corners do not measure 4.8mm. I blew up the photo of the spinel you're considering and I think it will measure closer to 3.7mm from corner to corner. (It was 6.4 mm on my screen at the widest part, and 5mm from corner to corner. Converting down, this means that if the widest dimension is 4.8mm, then the corners are 3.7mm apart.)

Since the setting you are considering is a 4 prong corner mount, I would look for a princess setting for a 4mm x 4mm with corner prongs.

I think. Email lan bo to make sure.

Thank you both for your advice! I will wait until I receive Gary's stone (just ordered it yesterday) and I will measure the cushion from corner to corner. Then I will contact lan bo before purchasing that setting...

Thanks again!

The size of the setting is probably O.K., but how will someone set that stone with four round prongs? A cushion cut like that either needs to have chevron prongs, which can be slightly flattened to match the angles of the cushion, OR it needs to have double prongs at the corners. Trying to use one round prong at each corner concentrates all of stresses that the stone sees directly at the weakest part of the stone. By using double prongs or a flattened chevron, you spread out those stresses and reduce the chances of damaging your stone, should it get banged against something.

Thank you for this info Michael, I didn't even think of that. I don't really like chevron prongs but I do like double prongs so I will try to go with that option. Do you think it would be possible for a local jeweler to adjust the current setting, sort of splitting each prong into 2 thinner ones? Or since the ebay vendor will customize for an added fee, should I request that they make the setting with double prongs? They do sell a larger setting that is similar to this one and it has double prongs so I'm assuming they can do it... Only thing is, I don't want the prongs to be bulky since the stone is fairly small. So if it is possible for a jeweler to adjust the current single prongs, I think I would prefer that. Let me know if you think that might be possible. Thanks again!

Unfortunately trying to split a prong which is already rather thin would not work well. The prongs need to have a minimal thickness to support the stone, (somewhere in the .8 to 1mm range), even if there are two of them. I would suggest asking about have the modification done by the seller since that would take care of it right at the start. Remember that getting prongs that look too heavy are not a problem since the person doing the stone setting can always reduce their size a bit, (it's not possible to make them larger, but easy to remove a bit of material).

Great! Before I bid on this setting, I will request that change from the seller (I am waiting to purchase it until I receive the stone, which should arrive tomorrow). Thank you so much for your advice!
