About the Art Deco Ruby and Diamond Ring:
The Art Deco movement of the 1920s and 1930s transformed fine jewelry through bold geometry, architectural symmetry, and striking contrasts between colored gemstones and diamonds. Platinum was particularly favored during this period for its strength and ability to support intricate diamond settings.
This ring reflects those design principles through its rectangular ruby centerpiece, geometric diamond arrangement, and contrasting precious metals. The six round diamonds introduce brilliance alongside the structured lines of the eight square-cut diamonds, while the yellow gold prongs emphasize the ruby's saturated red color.
The center gemstone is a 1.03-carat natural ruby with a GRS Pigeon's Blood color designation and no indications of heating. The combination of its documented color, untreated status, and emerald cut makes it the principal feature of the ring.
About Pigeon's Blood Rubies:
Pigeon's Blood is a prestigious color designation used by gemological laboratories for rubies exhibiting a particular vivid red appearance. GRS evaluates eligible rubies according to its own color classification criteria, making the laboratory's designation an important part of the gemstone's documentation.
Rubies showing no indications of heating are especially desirable in fine jewelry, as heat treatment is commonly used to improve the color and clarity of natural corundum. This ruby's GRS documentation identifies both its Pigeon's Blood color classification and its unheated status.
Set among 14 diamonds in a geometric platinum mounting, the 1.03-carat ruby combines the appeal of an untreated gemstone with the distinctive design language of the Art Deco period.
