The whole night sky, worn on one finger. This midnight blue moissanite crescent moon ring set centers a deep royal-blue marquise moissanite — roughly 5 × 10 mm and about 1.0 carat, glowing with indigo and starlit sapphire tones — framed by colorless moissanite accents that flicker like distant constellations. Sold as a two-piece set in solid 925 sterling silver with a rhodium finish, it is a celestial engagement ring for dreamers who want the romance of a starry midnight rather than a plain white stone.

A crescent moon and its stars
The setting is built entirely around the night sky: a curved crescent band cradles the marquise center like a moon holding a fallen star, and the pointed marquise tips echo the horns of a waxing crescent. Around it, tiny colorless accents scatter like a constellation. It is a bold, fantasy-leaning design that still reads elegant — the kind of non-traditional ring chosen by romantics, astrology lovers and night owls. Worn as a pair, the two bands frame the blue stone from both sides so it appears to glow in a halo of silver light. Find more pairings in our moissanite couples rings collection.
The engagement ring
Holds the deep royal-blue marquise moissanite in the crescent setting — the statement piece and luminous focal point of the set.
The matching band
A slender accented band that nests alongside the crescent, completing the moon-and-stars silhouette and lovely worn on its own.
The midnight blue moissanite
Deep royal-blue moissanite is a genuine, lab-grown gemstone — silicon carbide grown in a rich midnight tone rather than icy white. It is not a “fake diamond” or a simulated stone; it is its own gem, and it holds a color that glows between indigo, navy and starlit sapphire as the light moves. At 9.25 on the Mohs scale it is second only to diamond in hardness, so it wears beautifully every day. Explore the wider spectrum of tones in our colored moissanite engagement rings, and if you are weighing the gem against a grown diamond, our guide on whether moissanite is a lab-grown diamond is a clear starting point.
Colorless moissanite accents
Small colorless moissanite accents surround the crescent, adding crisp white sparkle and a starlit contrast that makes the midnight-blue center look even deeper and more dramatic. These are genuine moissanite too, chosen to match the fire of the center rather than fade beside it. For the symbolism and lore that make a blue stone feel so meaningful, our piece on moissanite meaning and symbolism is a lovely read.
Sterling silver with a rhodium finish
The set is crafted in solid 925 sterling silver and finished with rhodium — the same precious metal used on fine white gold. That rhodium layer gives both slim 1.6 mm bands a bright, mirror-white luster that frames the blue color perfectly and adds a protective shield against tarnish and everyday scratches. It is also nickel-free and hypoallergenic, so it suits sensitive skin. Pair it later with a plain stacker from our moissanite wedding bands for a layered look.
What the crescent moon symbolizes
Deep blue has long carried meanings of depth, loyalty and constancy, while the crescent moon stands for change and the promise that light always returns after the dark. Together they make a fitting emblem for a love meant to hold steady through every phase. If you would like to compare this gem with a lab diamond before deciding, see moissanite vs lab-grown diamond.

Sizing & care
Choose your size at checkout. If you are between sizes or unsure, contact us for guidance — and if the fit is not quite right, resizing is available and starts from a modest fee.

A soft, dry cloth restores the shine. With gentle care, this is a set made to be worn every day.
Frequently asked questions
Does this come as a set?
Yes. It is sold as a two-piece set — the crescent moon engagement ring plus a matching accented band designed to nest alongside it. The band can also be worn on its own as a stacking or promise ring.
Is midnight blue moissanite a real gemstone?
Yes. It is a genuine, lab-grown moissanite — silicon carbide grown in a deep royal-blue tone. It is its own distinct gemstone, not a simulated or imitation diamond, and the color is permanent.
What does the blue color look like?
It is a rich, deep royal blue that glows between indigo, navy and starlit sapphire depending on the light. The marquise cut still throws plenty of fire, so it sparkles while staying dramatic and moody.
How big is the center stone?
The marquise center measures approximately 5 × 10 mm, roughly a one-carat spread. The elongated marquise shape also makes it look larger on the finger than a round of similar weight.
Is moissanite durable enough for daily wear?
Very. Moissanite sits at 9.25 on the Mohs scale, just below diamond, making it exceptionally scratch-resistant and ideal for an everyday engagement ring.
Are the accent stones moissanite or cubic zirconia?
The accents are genuine colorless moissanite, not cubic zirconia. They keep their brilliance and clarity far longer and are matched to the fire of the blue center stone.
What metal is it made from?
Solid 925 sterling silver, finished with rhodium for a bright white luster and extra protection against tarnish and scratches. It is also nickel-free and hypoallergenic.
What does the rhodium finish do?
Rhodium is the same precious metal used to finish fine white gold. It gives the silver a mirror-bright shine and adds a protective layer that helps both bands stay looking freshly polished, framing the blue beautifully.
Does it come with certification?
Yes. Each moissanite ring set comes with a GRA certificate documenting the center stone specifications.
Will the silver turn my finger green?
No. Genuine 925 sterling silver with a rhodium finish does not discolor skin. Green marks come from cheap copper-heavy alloys, not real sterling silver.
What size should I order?
Select your ring size at checkout. If you are unsure or between sizes, contact us for guidance. Resizing is available and starts from a modest fee.
Are the stones ethically sourced?
Yes. All of our moissanite is lab-grown, and our materials are ethically sourced and conflict-free, so you can wear the set with complete peace of mind.
Does it arrive gift-ready?
Every order ships in a free luxury velvet gift box and is backed by our lifetime warranty — ready for a proposal or to give as a keepsake.
