How Sapphires Are Cut and Polished?

The cutter is known as a lapidary or faceter.

The cut and polish on a sapphire, or any gem stone, is extremely important .Sapphires are unique in the fact that the stone has an almost unlimited choice of cuts. The majority you will find as Oval, Round and Cushion cuts. However, you will see in our store that we carry a full range of cuts, including some very unique fancy cuts.

Many gem stones are limited to the cuts they can have, depending on the natural make-up of the stone. For example, you will see many Tourmaline or Emerald’s taking on an Emerald Asscher or Square cut, this is due to the natural crystals which are formed in an elongated shape similar to an Emerald cut, which makes cutting the stone along the lines of the natural crystal much easier.

 

Sapphires crystals are formed as a hexagon shape ( Drawing on the left is of a sapphire crystal make-up ). This not only allows for a much more diverse set of cuts, but also explains in part (to) why these beautiful gem stones are so durable.

A clean gemstone that has been cut and polished to a high standard will return a larger percentage of light and glitter to the eye.

The polish of a sapphire is equally important. The Sapphire Ring Co. estimates that around 20% of our sapphires each year are sent off to be re-polished here in the USA. This is not to say that the polish the sapphire comes to us is generally poor, only that we go to great lengths to ensure that every single sapphire is cut and polished perfectly to meet our own high standards. We are very fortunate to have our own gem cutter who is highly skilled with the faceting and polishing of Diamonds, Sapphires and Rubies and he is able to take a well cut & polished Sapphire to the next level creating a cleaner cut, allowing for a much better finish, and ready for each custom ring setting.
