Story

Following in the tradition of the 18th and early 19th century when portrait miniatures mounted in jewelry were covered in glass to protect the watercolor comes the portrait diamond. Newman’s “An Illustrated Dictionary of Jewelry” defines a portrait diamond as “a thin diamond with two large, flat, parallel surfaces so that a viewer can see through it to recognize an object under it, without distortion by refraction…sometimes such a diamond is found in nature (called a flat) and is cut and beveled for use as a glass over a miniature portrait …”.

This is truly a one-of-a kind ring never to be seen again! It features a diamond shaped portrait diamond of an estimated 1.08 carats which looks as though it is closer to a 1.75 carats! Interesting to note that this cut is not as deep as a round or similar cut diamond but wider and more planar. The E-F color is amazing with a view as clear as a window and SI1 clarity. The gem is set in a lozenge shaped bezel with mille grain accented edges. A pierced and open work platinum gallery provides the ring with a classic and timeless look which allows rays of light to also enter from below the diamond. Split shoulders each set with a petite round cut diamond accent stone segue into a smooth silken platinum shank with delicate linear details. You will be able to see through this to your finger, so the diamond reflects what is covers!

This ring is accompanied by an EGL USA certificate for the center diamond with an estimated retail replacement value for the diamond alone of $11,150.

Date Diamond is earlier 20th century; mounting is modern.

Historical Note: There is a 25 carat table portrait diamond in Russia known as the Tafelstein which is reported to be the largest example of this type of diamond in the world. It covers a miniature watercolor portrait of Emperor Alexander I by the English portraitist George Dawe. Purportedly discovered in India and cut from a larger stone, the diamond is absolutely pure and transparent, except for a tiny air bubble in the corner by the mount with a perfectly polished surface. Several of the famous Faberge Russian Imperial Easter eggs were set with smaller portrait diamonds.
