Description

This vintage old European cut diamond six-prong platinum engagement ring is the ultimate piece from my personal collection, but I decided it's time to part with it!

The center diamond is 1.80 ct, F color, and VS2 clarity. Importantly, it is certified by the most respected gem authority: Gemological Institute of America (GIA). Please go check it out the Report, Number: 1182613923.

As you may know, a majority of the old cut diamonds on the market have a J color or lower and have visible inclusions. Sadly this is due to the fact that over time many of the high quality old cut diamonds have been recut to make modern round brilliant diamonds. Thus most high quality old cut diamonds haven't survived. So, an old cut stone in F color and with few inclusions is extremely rare. In fact, high quality stones like that are currently priced at a value higher than their modern round brilliant counterparts!

The cutting style of the center stone is technically a transitional cut style, which is a diamond cutting style in between traditional old mine/old European cut and modern round brilliant. It was popular from about the 1920s through the 1940s. This style is characterized by a slightly bigger table, longer and slimmer facets, with lower crown, and a smaller culet compared to old European cut. However, unlike modern round brilliants, the girdles of these stones remained unfaceted/unpolished. GIA generally terms the diamonds in this cutting style as "Circular Brilliant" instead of "Round Brilliant" (which is a term for modern round cut diamonds).

In my years of experience in vintage jewelry collecting and observation, the most beautiful and charming old cut diamonds come from this category as they exhibit a gorgeous flowery pattern with wonderful light play in a lot of light environments. This one is no different, and frankly it is absolutely charismatic with literally perfect faceting, ideal proportion, and lively reflecting the different colors from the surrounding environment. In my opinion, this stone is a textbook example of a transitional cut diamond.

The center diamond is mounted on a vintage 6-prong platinum setting with two small single cut diamonds on each side.
