Beautiful vintage engagement ring! A halo of old Mine Cut Diamonds surrounds a round faceted Sapphire, all done in solid 10k gold. It is estimated to date from the 1920's.

The ring setting is approximately 3/8" in diameter.  The lovely deep blue Sapphire is estimated at 6mm in diameter. Each of the diamonds in the halo is estimated at 0.03 carats. There are 12 diamonds totaling an estimated 0.36 cts.

This ring size is 5.25. It can be sized, please inquire with the desired size for an estimate.

In very good to excellent condition overall, the Sapphire has a few tiny chips only visible under magnification. This is consistent with age and regular use.

Overall approximate weight is 2.03 gram. Unmarked, carefully tested.

We measure bracelets based on their wearable length, not the actual length. We do this because chunky bracelets will have a smaller wearable length than the actual length as the thickness of the bracelet reduces the internal measurement. If at any time you would like the actual length and is not in the description, please feel free to contact us.
