I repaired the Table and star facets of this
Pink Spinel while it was still in the ring

The table is the most vulnerable part of a gemstone because it is the highest facet and up there where it can get bumped and scratched.

A jeweler sent me this Spinel which had been chipped. He wanted me to remove the chips without having to remove it from the mounting. This saves the expense and risk of un-mounting and re-mounting the gemstone.

Most of the time I can do the table while it is in the mounting but no other facets. In some occasions I can hold the ring at an angle which enables me to do the star facets also. That was the case with this ring.

As you can see, the chips are on both the table and also the star facets on one side.

Most of the time I can re-polish only the table. This time I can also do the star facets because there are no obstructions in the way.


The Spinel is on the polishing wheel

I need to mount the ring in a special way in my machine to do the table.


Polishing the stars

Here you can see I am leaning the machine at the correct angle to polish the chips out of the star facets.

After I do the stars which had the chips, I also need to do the stars on the other side to make them equal.


Finished re-polishing the table and star facets

You can now see that all of the chips are gone and the pink Spinel looks like nothing ever happened to it.


The finished Ring

The ring now looks like new again!
