Antique platinum filigree statement ring with diamonds and a sapphire, circa 1920

Fabulous antique platinum ring with a 1ct sapphire and 2cts in diamonds.  The diamonds are all old cuts, VS1-2 in clarity, F-G in color.  The sapphire is a clear inky blue.  The ring measures 3/4" long, it's a size 6 1/4 and can be sized.  Excellent condition with the original fitted box, circa 1920.

I love this too!
