I faceted this Colorado Topaz into a cushion cut

Topaz is one of the gemstones which can be found in Colorado. Collectors dig in locations where Topaz has been found and they sometimes make very impressive discoveries.

The owner of this Colorado Topaz wanted it faceted into a cushion cut and to achieve the maximum yield possible with his piece.

This was a very clean piece of material and sparkled with a lot of brilliance when it was finished.

See the steps that I used when faceting it.


Rough Colorado Topaz crystal

This is the piece of rough Topaz which the customer brought to me which he had found here in Colorado.

Dopped preform

Here you can see that I have shaped the Topaz into a cushion cut preform and also glued it to a dop stick.

It is now mounted into my faceting machine.

I form the cushion shape by hand.


The first facets

You can see the first 4 facets I have placed on the pavilion in order to set the main angles and to also center the culet.


More facets on the pavilion

You can see that I have added many more facets and a more complex pattern has developed.

A pattern such as this produces a much more brillant finished gemstone than a step cut would.


Polishing the first facets

Here you can see that I have started polishing the first couple of facets.

I use a special lap which puts a very high polish on Topaz.


Polishing more facets

You can see that more facets have been polished.

I do them in a particular order and in a symmetrical fashion in order to keep the pattern balanced.


Polishing on the faceting lap

Here you can see the polishing lap that I am using.


Faceting the crown

I have put the first few facets onto the crown.


Polishing the crown

Here you can see the finished stone.

The finished stone is very brilliant.
