FAQ

Do you repair diamond anvils?

Yes, we repair diamond anvils. We can repolish the culet, with or without the 8 or 16 bevels around it. If necessary, we also repolish the larger facets around the culet. How much we polish away depends on the damage (because of microcracks it is not possible to predict how much material we need to remove to clean the culet) or on the request of the customer. Sometimes customers want to receive a different anvil height.

What colour do your rough diamonds have?

The colour of our type IA diamonds is called "commercial white". This means that these diamonds are white, with a light tint of yellow. Most of our type IIA diamonds are toplight brown. Of course both types of diamonds are selected for their transparency and purity.

 

What are the tolerances on your diamond anvils?

The tolerances on the most critical dimensions of the diamond anvils are as follows:
Culetsize: +/- 10 micron.
Parallellity of the culet to the table facet (= largest facet): within 5 minutes.

 

The tolerances on the less critical dimensions of the diamond anvils are as follows:
Diameter: +/- 25 micron.
Height: +/- 25 micron.


Can you measure the birefringence of diamonds?

Under polarized light, you can get an indication of the birefringence of a diamond. However, we have equipment to really measure the birefringence of our diamonds.


What is the smallest culet you can polish?

The smallest culets we polish routinely have a diameter of 100 micron with bevels of 100 microns long. However, some people want to go beyond this.
We think a 10 micron culet should be possible.
