Save 23%The 4.5mm Round Moissanite Tennis Necklace is a continuous line of about 4.5 mm round brilliant moissanite stones, each prong set, running around the neck in one unbroken row. Single-row prong-set round tennis necklace, box clasp. It is made in 925 sterling silver and in solid 10K, 14K and 18K gold in yellow, rose and white, in four lengths from 14 inches to 20 inches, and it fastens with a box clasp with a safety lock. A certificate of authenticity for the moissanite is included at no extra charge.
The stones measure about 4.5 mm across, as seen in the product images. At the base length of 16 inches the total carat weight is approximately 16.00 carats. Total carat weight changes with length because a longer necklace holds more stones. As a guide, a 14 inch length carries approximately 14.00 carats, an 18 inch length approximately 18.00 carats and a 20 inch length approximately 20.00 carats. Figures are approximate and vary slightly with the metal and the exact stone count.
Every Mapple Gems moissanite piece includes a certificate of authenticity for the moissanite at no extra charge. It confirms that the stones are genuine moissanite and ships with your order.
Moissanite is silicon carbide, first identified by the French chemist Henri Moissan in 1893. Natural moissanite is extremely rare, so the moissanite used in fine jewelry today is created in a laboratory. Its refractive index of about 2.65 is higher than that of diamond, so it throws more fire, which means more colored flashes of light. At 9.25 on the Mohs scale it is second only to diamond in hardness, so it resists scratching and holds its polish. Because it is created rather than mined, moissanite is a conflict free choice and costs a fraction of a mined diamond with a comparable look.
A tennis necklace works on its own for a clean evening look and layers well with a plain chain or a pendant. It suits weddings, engagement parties, anniversaries, birthdays and special occasions, and it is a lasting gift for a partner, a wife, a mother or a friend.
A tennis necklace is a flexible necklace made from a continuous line of matched stones set at even intervals, with no pendant and no break in the pattern.
At the base length of 16 inches the total carat weight is approximately 16.00 carats. It changes with length because longer lengths hold more stones.
Colorless moissanite in a round brilliant shape, prong set, about 4.5 mm.
The gold options are solid 10K, 14K or 18K gold throughout, not plated. The silver option is 925 sterling silver.
Sixteen inches is the classic length and the most popular choice. Choose 14 inches for a choker fit or 18 to 20 inches for a longer drape.
Yes. A certificate of authenticity for the moissanite is included with every order at no extra charge.
