Description

This AAA-grade round faceted ruby has the deep red color and durability that makes ruby one of the world's most desirable stones. This stone shows the superior cut, color saturation and active scintillation required to be classified as a top-quality AAA-grade stone. Use the stone in rings, earrings or to add a classic ruby-red accent to a larger jewelry design. Ruby is the birthstone for July.

Ruby, a variety of corundum classified as a precious stone, is one of the world's most valuable gemstones. The color of a ruby is due to a trace of chromium in the stone; the amount of this substance determines the depth of color. With its hardness and durability, ruby is an excellent choice for all types of jewelry. Through the ages, ruby has been considered to be a gem of nobility, credited with engendering sensuality and vitality.

Round-cut gemstones are highly popular and the most commonly available. Rio round gemstones are calibrated for size and hand inspected to ensure maximum attractiveness.
