We know the diameter of a Gem is what folks see, but if you use these You must check the depth before setting. Your Gem can't help it if its cullet (bottom point) can not allow the girdle (widest) to be captured by the prongs, securing the Gem. If you try and it just splays out. Choose another mount with more room. Don't throw these out, just use pliers to bring them back into shape, measure your mounts diameter against what they were when new. They are still good, for a skinnier Gem. Brush up on how to measure a Gem. Shape matters in how you obtain the Industry Standard view. With new "Cuts" becoming popular, which mounting you choose to secure Gems becomes very important.

these items are very easy to use as long as you measure out the stones correctly. only took a few minutes to find a few gems to set in these and it was easy as 1 2 3 and tah dah earrings ready to sell . the settings are very thick so i am certain the stone will not fall out due to thin, weak prongs g this site and their top of the line silver items

Excellent setting and easy to use!

These are super easy to use. It’s easier for me to use a tool or anything to give me a grip. A firm rubber helps also. You really don’t need any special equipment. Very fun to do with my 12 year old. Super easy and fast.

The snap & set works like a charm! so easy to use

I love the snap &set feature! Easy to snap a 5mm gem into with no need to bend the prongs. Feels very secure! And an incredibly low price!

awesome settings!

This is very fun and easy to use just by snapping the jewelry in place. Price is really good too.

Snap & Set is the way to go!

Substantial and easy to work with.

Negative - don’t come with earring backs which is just odd. Make them more expensive or whatever but issue with backs. Have it be an option to choose IF Backs not required

The price made this purchase easy and the look made my studs sparkle!
