1920''S TIFFANY & CO - MINERS CUT DIAMOND RING

[EBEY4BONNIE]

I have an old 1920''S Diamond ring that is marked TIFFANY & CO on the inside of the band. I was told by a jeweler that the center 1/2 carat diamond is a "Miners Cut", that the center diamond has no inclusions and that it is almost white. I had also been told by another person that the center diamond was European Cut. Unfortunately I don''t know what the difference would be.

Could you advise me as to what a "Miners Cut" is and what a European Cut means? I listed the ring for sale on eBay a few days ago and I am getting concerned that I did not put enough of a reserve on this beautiful ring.

The jeweler also said the ten diamonds surrounding the center diamond measure six to eight points each. I have someone asking what points are and I am not sure exactly what a point is.

An old mine cut is not circular in outline. An old European cut is generally circular around the girdle. It is an indication of the relative age of the cut stone and the technology of diamond cutting during that period when it was performed.

A carat is 0.2 grams
A point is 1/100th of a carat or 0.002 grams
