Auction Wally,

I saw you referenced in the Wall Street Journal, and I was excited to get my Antique French Tiffany Co. Engagement Ring appraised.

Here are the item details and pictures:
– I purchased the ring from a reputable Jeweler, Francis Lynch -( francislynch DOT COM). He had it from an estate sale. The ring has had 2 owners, myself, and the original owner’s family. The ring is 18kt white gold Tiffany & Company, 0.50 carat D color, Internally Flawless diamond ring circa 1920. The ring is in a 10 prong stylized solitaire with small Swiss cut diamonds with a total of 0.10 carats total weight. The ring is stamped 750 and T & Co. on the inside of the shank and has french hallmark. It is currently sized to 8.5, the box has some damage, but I have an additional Tiffany Case due to the condition.

Please let me know if I can add any additional information to help the valuation.

AW says: That is truly a beautiful ring! Let me say here, that you’ve given me enough information to do an appraisal. But readers must understand that doing a jewelry appraisal online is has certain rules.

It is only possible when good information about the appraisal subject is given. It must be taken for granted the the information is 100% true, as there is no way to physically inspect the piece.

That said, viewing the pictures you’ve sent of this ring and it’s box, I can make an appraisal based on the information you’ve provided.

As a D color diamond (a white or a colorless diamond) this is set in white gold as it should be. The reason for this is to achieve the best reflection of the diamond itself. Yellow gold would distort the color.

The round cut of the diamond is appropriate for the age of the ring.

The clarity and lack of internal flaws of course enhances value. As well as the fact that it was sold by Tiffany & co.

The small diamonds that surround the main stone add to the beauty of the piece. However, when it comes to diamond weight, you must get to at least a 1/2 ct to garner serious value.  Your ring has all the qualities of a desirable diamond ring.

Retail value: $5,750
