Re-polishing the Crown of a Rhodolite Garnet.

This is a cushion shape Rhodolite Garnet which a jeweler sent to me to have the crown re-polished

We mount a stone like this in our faceting machine and then find each of the facets and re-polish each of them.

Below, you will see photos and description of the cutting process.

You can see in this photo that the crown of this gem is heavily worn with scratches and chips from years of wear.

The jeweler asked me to re-polish the entire crown but leave the chips on the left side of the stone (in order to not reduce the length of the stone) because that edge will be hidden under the bezel when he re-mounts the stone back into the mounting.

Notice how the color of the stone is subdued when it is scratched, much like frosted glass looks. Re-polishing will help bring out the color which is there.

After re-polishing

After re-polishing, you can now see how much brighter the stone looks and how the color comes out.

You can see minor amounts of roughness left on the left girdle of the stone which the jeweler asked us to leave there. That will be hidden after he mounts the gem.
