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
Shipping Stones for tension set rings:
Most people use FedEx or Registered Mail for shipping precious stones. When
using Registered Mail, a box with all sides taped with brown packing tape must
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.
