Are miner cut diamonds worth more than diamonds now?

Napoleon I Diamond Necklace
A friend of a friend says the ring their fiancee is giving them is quite expensive because it has "miner" cut diamonds. Is this true?

It's "old mine cut."

This cut of diamond was prevalent in the 1800's up until the time in which the Old European cut diamond took over. Vintage stones can be worth more that modern cuts--not so much because of the cut as it is because of the quality of the stone. A very well cut Old Mine Cut stone is quite brilliant. Lots of diamonds that are faceted and set these days would have been put in drill bits years ago. The modern cuts have been developed to take full advantage of the diamond's natural refractive characteristics.

Vintage cuts used to be a disadvantage (and sometimes still is) when valuing a diamond, but in recent years, antique cuts and ring mounts have become a popular choice for engagement rings. This new market drives the pricing of old diamond rings. Your friend's ring is probably comparable in price to a modern ring with the same diamond weight.
