This magnificent Art Deco era ring features a natural light blue star sapphire cabochon set in platinum, with diamonds accenting the sides. It came to me from an estate in Florida.

Included is a written appraisal from an independent local GIA-certified gemologist complimentary (a value of $50).

The appraised retail value is $10,595

I outline points of the description as per the appraisal:

Ladies Antique Art Deco ring featuring a 6.50ct greyish light blue cabochon-cut sapphire
The natural sapphire shows the phenomenal asterisk making this a genuine Star Sapphire.

Color: Grayish blue
Luminescence: brilliant

There are 6 baguette and 6 single cut diamond accents on the sides.
The diamonds are VS2 in clarity and H color. (.10ct total weight)

The ring is composed of solid platinum and weighs 7.5 grams.
It has the typically geometric lines of the period and is aged circa 1920-1930s.

There are no noteworthy flaws for a ring of this age.
It’s currently a finger size 4 ½ (US) but can be sized by a good jeweler.

You can view the copy of the appraisal, along with more details in the last photo.

Regarding the star: Since this sapphire has some opacity, it was hard to show the star in a photo. The last picture shows the ring in outside sunlight, in an attempt to capture this. The very bright small spot is the reflection of the direct sun, and the other crossed lines are the features of the stone, shown in this light.


Shipping will include insurance and is quoted for the U.S.

As discussed, this listing will allow for a return with notification within three days and if received in same condition, unaltered. Thanks!
