This round simulated emerald doublet features the striking green color of emerald at an affordable price point. Emphasize the bold color by using it for a custom pendant design or partner it with complementary-color stones in a bold, multicolor necklace, ring or brooch. Emerald is the birthstone for May.

Producing consistent green colors in laboratory-created gemstones can be difficult. By using a tinted adhesive to connect two sections of clear lab-created spinel at the girdle, creating a doublet, labs can produce consistent color throughout the stone. Unless the stone is immersed in highly refractive liquids, it is impossible to tell that only the girdle zone of a doublet has color. Simulated emerald allows you to offer customers the color and characteristics of this gemstone at a lower price point.

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.
