A 6×8mm oval midnight blue moissanite at the center of a low, wing-shaped cluster, with two blue marquise moissanite reaching out to either side and clear marquise and round moissanite filling the space between. The cluster is fixed into the chain at both ends, so it lies flat against the collarbone rather than swinging or spinning. Solid 925 sterling silver with a rhodium finish.

The Blue
Deep, Not Pastel
Midnight blue moissanite sits close to a royal or deep sapphire blue, dark enough to read as navy in low light and electric under a lamp.
Blue on Blue
The two marquise side stones are blue as well, not clear. That carries the color out across the whole cluster instead of leaving one blue dot in a field of white.
Fire, Not Just Color
Moissanite's refractive index is higher than diamond's, so even a saturated stone throws rainbow flashes rather than sitting flat and dark.
Not a Sapphire — and We Say So
Blue moissanite is often sold as a sapphire look-alike, and it does read that way across a room. But it is not sapphire, and we do not call it that anywhere on this page. It is silicon carbide with a blue body color, grown in a lab. At 9.25 on the Mohs scale it is harder than sapphire's 9, and it has considerably more fire — a sapphire absorbs light where moissanite splits it.
A Cluster That Lies Flat
This is not a pendant on a bail. The cluster is soldered into the chain at both ends, which means it sits where you put it — centered, face-forward, flat on the skin. Pendants spin and end up backwards; this does not. It also sits high enough on the chest to layer a longer chain beneath it.
What Moissanite Is
Moissanite is silicon carbide — a genuine mineral, first identified in a meteorite crater, now grown in a lab. It is harder than every gemstone except diamond, which makes it a sensible choice for something worn daily. Our guide to moissanite meaning covers the stone in more depth, and moissanite versus cubic zirconia explains why the two are not interchangeable — every stone in this necklace is moissanite, not CZ.
Metal and Chain
Solid 925 sterling silver throughout — cluster and chain — with a rhodium finish, the same platinum-group metal used on white gold. It keeps the surface bright white, resists tarnish and is nickel-free. The cable chain is 18 inches with a spring-ring clasp.
Find it in our moissanite jewelry and sterling silver necklaces. The same cluster is available with a gray moissanite center, and with a natural moss agate and opal center.

Care
Moissanite is hard and chemically stable, so cleaning is easy: warm water, mild soap and a soft brush, then dry with a lint-free cloth. Store it flat in the velvet box so the chain does not kink. Put it on after perfume, hairspray and lotion, and take it off before swimming or the gym — chlorine wears the rhodium finish, not the stones. Our guide to cleaning sterling silver covers the metal.
Frequently Asked Questions
Is this a sapphire?
No. It is blue moissanite — silicon carbide with a blue body color, grown in a lab. It looks like a deep sapphire from a distance, but it is a different mineral, and we will never label it sapphire.
How big is the center stone?
6 × 8 mm, oval brilliant cut — roughly the visual size of a 1.5 carat oval diamond. It reads as a real center stone rather than an accent.
Are the stones real moissanite?
Yes — every stone, blue and clear. There is no cubic zirconia in this necklace.
How dark is the blue?
Deep. In low light it reads close to navy; under direct light it opens up to a bright royal blue with rainbow flashes. The blue marquise stones on either side match the center.
Will the blue fade?
No. The color is inherent to the crystal, not a coating or a surface treatment, so it cannot rub off or fade in sunlight.
How long is the chain?
18 inches with a spring-ring clasp. That is princess length, which sits just at or below the collarbone on most people.
Does the cluster flip or spin?
No. It is fixed into the chain at both ends rather than hanging from a bail, so it stays face-forward and flat.
Is it real silver?
Solid 925 sterling silver throughout, cluster and chain, hallmarked, with a rhodium finish. No brass or base metal.
Will the silver tarnish?
The rhodium finish acts as a barrier, so it resists the darkening untreated sterling develops. If it thins after years of wear, we can refinish it.
Can I wear it every day?
Yes. At 9.25 on the Mohs scale moissanite handles daily wear better than almost anything except diamond. Take it off for swimming and the gym to protect the finish.
Does this design come in other stones?
Yes — the same cluster is available with a gray moissanite center, and with a natural moss agate and opal center in sterling silver or 14K rose gold vermeil.
