This elegant solitaire pendant necklace features a single round lab created emerald measuring approximately 7.8 x 7.8 mm, set in rhodium-plated 14kt white gold. The three-prong setting allows maximum light into the stone, enhancing its rich green color and brilliance. The open wheat-link chain measures approximately 18 inches and is adjustable to 16 inches, secured with a lobster clasp for a secure fit.
Lab created emeralds share the same chemical composition, physical properties, and optical characteristics as naturally mined emeralds — both are a variety of beryl colored by chromium and vanadium — but are grown under controlled laboratory conditions. As is standard in the industry, colored gemstones offered have been enhanced in the production process. The piece ships fully insured via air shipping.
