This oval 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.
The oval cut is an even, symmetrical shape but elongated. The arrangement of its facets is similar to that of a round brilliant, designed to maximize light and color.
• Because laboratory-created spinel doublets are assembled with an adhesive, it is important not to apply heat to the gemstone. To be safe, clean these gemstones using warm, soapy water and a soft brush.
• Unless precisely calibrated to an exact size, gemstone sizes vary slightly. Rio allows a tolerance of +/– 0.2mm for gemstones larger than 4mm.
