This natural ruby is precision-cut by Swarovski Gemstones™ to be perfectly symmetrical with dependably consistent proportions between crown, girdle and pavilion. This size displays a bright red color and, because it is so carefully calibrated, the stone is ideal for pave setting and for use as an accent stone in your custom designs. 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. With its hardness and durability, ruby is an excellent choice for all types of jewelry. 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. 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.
