Stone Information for Tension Sets
Choosing a stone is a very important part of buying a tension set ring.
We supply a CZ or lab created colored stone at no additional charge. They are available in all birthstone colors. We are also able to source diamonds or other precious stones.
CZ is not nearly as hard as diamond, so occasionally they can crack from the tension coupled with an impact onto a solid object. Fortunately they are easily replaced, and we offer lifetime replacement of CZ's or the lab created stones at no charge should it ever become necessary. You would normally insure precious stones on your homeowners policy.
Tension Set Preferences for Diamonds:
We prefer the clarity to be SI1 or better. Obviously, a cleaner stone is a stronger stone. Most of our clients prefer to shop around themselves and get exactly the stone that they are looking for. Diamonds are such a blind item that just a slight difference in specifications can cost thousands of dollars. There are many reputable diamond sites on the internet and there are also some good diamond informational sites. We would be happy to recommend a few of those.
Other Stones that work well:
Sapphires and Rubies, which are very hard stones.
Some stones such as emerald are so soft that they are not suitable for tension setting.
Shipping Stones for tension set rings:
Most people use FedEx or UPS w/ signature required for shipping precious stones. It is best to ship in a box that will protect the stone.
If you are still wary of sending your stone to a complete stranger, it's easy to go to your local jeweler and have your stone mapped. This involves getting the stone accurately measured and having its unique fingerprint of carbon inclusions drawn to scale on a drawing. He can then recheck the stone in the ring upon its arrival back to you. This will ensure that you get the exact same stone back. Some stones have a laser engraved serial number on their girdle. We can orient the stone so that the number points outward when mounted.
Another Option: is for us to make a ring with a CZ to be changed out with a diamond at your local jeweler. It would be best to ask the jeweler his feelings about doing that before assuming he would do it.
