Starry Night® Stardust Wedding Band in Black Tungsten Carbide (4mm)
Starry Night® Stardust Wedding Band in Black Tungsten Carbide (4mm)
A slim 4mm polished black tungsten Starry Night® Stardust band, its channel drifting with crushed galaxy sandstone and gold-tone foil that glimmers like a night sky. Narrow enough to wear as a women's band, a stacking ring, or a low-profile men's band — a whole galaxy on the hand, without the bulk.
The inlay: stardust over a night sky
Crushed galaxy sandstone — also known as blue goldstone, deep blue with star-like metallic flecks — mingles with drifts of gold-tone foil, all hand-arranged and sealed under smooth resin so the finish is permanent. Because the inlay is set by hand, every ring's stardust pattern is one of a kind, a detail that makes yours truly your own.
Slim, cosmic, and easy to pair
At 4mm the band sits light on the hand — a favorite of stackers, Night Court aesthetics, and anyone who wants the cosmos in an understated width. The black is bonded into the tungsten alloy itself, roughly four times harder than titanium, so it keeps its dark finish and holds up beautifully to everyday wear. It also happens to be the exact design match to our 8mm Stardust, so it pairs effortlessly into a matching celestial couple rings look. Explore more in the full Starry Night rings collection.

4mm Stardust band FAQs
Is the gold in this ring real gold?
The gold accents are decorative gold-tone foil sealed in the resin inlay, chosen for its warm celestial glow. For solid gold, explore our men's gold rings.
Is this a men's or women's ring?
Both — the slim 4mm width wears beautifully as a women's band or stacking ring, and as a low-profile men's band.
Does it match the 8mm Stardust?
Yes — same black tungsten, same galaxy sandstone and gold-tone foil inlay, just 4mm wide, so the two pair into a matching cosmic look.
What is galaxy sandstone?
Also known as blue goldstone — a deep blue material filled with metallic flecks that sparkle like stars.
Will every ring look the same?
No two are identical — the inlay is hand-arranged before the resin sets, so each ring carries its own stardust pattern.
Will the black color stay?
Yes. The black is bonded into the tungsten carbide alloy itself, not painted or plated, so it is permanent.
Is a 4mm band durable?
Yes — width doesn't change tungsten's hardness, so this 4mm band is just as scratch-resistant as our wider rings, simply lighter on the hand.
Will tungsten turn my finger green?
No. Tungsten carbide is hypoallergenic and won't discolor skin.
Can I stack it with other rings?
Yes — the slim dome profile stacks cleanly with engagement rings and other slim bands, a favorite styling for the Stardust design.
Can I shower with it on?
Yes. Tungsten doesn't rust or tarnish and the inlay is sealed in resin, so it wears comfortably day to day.
Does this come with a gift box and free shipping?
Yes — a free luxury velvet jewelry box with every order and free U.S. shipping.
