The solid 14K white gold version of our kite galaxy sandstone bridal set — a glittering midnight-blue kite stone at the center, scattered with countless points of light like a clear night sky, surrounded by a kite-shaped black onyx pavé halo and paired with a matching chevron contour band accented with black onyx and a marquise black onyx at the V-apex. Built in solid 14K white gold (no plating, no sterling core). Galaxy sandstone — known to collectors as blue goldstone — is a jewel-toned artisan material famous for its dense, shimmering starfield, an effect no natural stone reproduces. It's the celestial centerpiece of our Starry Night collection, inspired by the Great Rift of the night sky, now in heirloom-tier solid gold.

The Starry-Night Stone
Galaxy sandstone — known to collectors as blue goldstone — is a deep midnight-blue artisan material shot through with thousands of tiny copper crystals that flash and shimmer like stars as the light moves. The technique behind it dates back centuries, and it's treasured for one reason above all: nothing else captures the look of a galaxy quite like it. Where a sapphire gives you depth of color, goldstone gives you the night sky itself — a glittering, living starfield across the whole face of the stone.
Pairing it with solid 14K white gold gives you the best of both: a setting built to last a lifetime and hold its value, framing a center stone chosen purely for its cosmic drama. If you'd love this design with a natural or lab-grown gemstone center such as blue sapphire instead, just message us for a custom quote.
The Engagement Ring
Kite-cut galaxy sandstone center (5×8mm) surrounded by a kite-shaped pavé halo of black onyx that traces the center stone's geometric outline, on a thin solid 14K white gold band.
The Chevron Contour Band
V-shape chevron silhouette with round black onyx accents fanning up each side and a marquise-cut black onyx at the apex point (pointing down). Designed to nest below the engagement ring.
Solid 14K white gold — the heirloom tier
"Solid gold" means the entire ring is gold alloy throughout — no plating, no gold-filled construction, no sterling silver core, no rhodium finish layer. 14K white gold is gold alloyed with palladium and other white metals to produce the cool bright white tone, hard enough for daily wear, and built to last indefinitely. A solid 14K white gold ring doesn't need replating, doesn't wear through, and holds resale and inheritance value in a way that lighter constructions don't.
This is the meaningful difference between this version and the sterling silver version of the same design: the solid gold construction is built to last a lifetime and beyond. For a buyer who loves the cosmic galaxy sandstone design but wants the lasting value, durability, and heirloom quality of solid gold rather than sterling silver, this is the version to choose. The cool bright white gold is the right backdrop for the deep cosmic blue and black palette, keeping all eyes on the galaxy sandstone's sparkle. Available in 14K white gold (this listing default), 14K yellow gold, or 14K rose gold on request; 18K upgrades available at additional cost.
About the galaxy sandstone (blue goldstone)
Galaxy sandstone — collectors call it blue goldstone — has a deep midnight-blue body filled with countless tiny copper crystals that ignite into sparkle as the light shifts across them. The effect is pure cosmos: a dark, rich blue field scattered with glittering points of light, like a clear night sky or a distant nebula caught in stone. The kite cut, with its pointed base and angled crown, spreads that starfield across a generous surface so the sparkle is the first thing anyone sees.
It's an artisan material with real heritage — the craft of suspending copper crystals to create this shimmer goes back centuries — and it remains prized for a cosmic brilliance that natural stones simply can't reproduce. For a celestial, starry-night, galaxy-themed ring, this is the material that delivers the effect at full intensity.
Like fine collector stones, goldstone rewards a little care — it has a smooth, lustrous surface that stays brilliant when treated gently. The solid gold setting around it is built for daily life; the center simply prefers to be kept away from hard knocks and harsh chemicals, the way you'd treat any special piece. (Full care notes below.)
About the black onyx accents
The accent stones — the kite-shaped pavé halo around the center, the round accents on the chevron band, and the marquise accent at the V-apex — are natural black onyx, a variety of chalcedony quartz with a deep opaque black body. Most commercial black onyx, including the stones in this set, is heat-treated to achieve uniform black saturation, which is permanent, stable, and industry-standard. The underlying material is real natural chalcedony quartz.
The deep opaque black of the onyx is the perfect frame for the galaxy sandstone: it deepens the "dark night sky" effect, making the sandstone's sparkle read even more like stars against a black cosmos. On this solid gold version, the black onyx accents can be upgraded to black diamond on request — message us before ordering for a custom quote if you'd like the all-natural-gemstone accent upgrade to match the solid gold construction.
About the starry-night celestial design
This set is built around the cosmic aesthetic — the Great Rift of the Milky Way, the deep dark sky scattered with stars, the sense of boundless wonder in the night sky. The deep blue glittering sandstone is the "galaxy," the black onyx halo and accents are the surrounding "dark cosmos," and the kite geometry gives the design a modern, celestial, almost crystalline structure. Worn together, the engagement ring and chevron band frame the galaxy stone in a complete cosmic composition.
The set fits celestial, galaxy, cosmic, starry-night, and astronomy-lover aesthetics — for buyers who want an engagement ring that captures the night sky rather than a traditional white-stone solitaire, in heirloom-tier solid gold construction.

Sizing & care
True to size and comfort-fit. If you don't know your size, message us before ordering — we can send a complimentary ring sizer.
Like fine collector stones, galaxy sandstone has a lustrous surface that stays at its brilliant best with gentle care — even though the solid gold setting around it is built for daily life. Keep it away from hard knocks (avoid impact on hard surfaces), harsh chemicals, ultrasonic and steam cleaners, and sudden temperature changes. Slip the ring off before cleaning, gardening, swimming, or exercising. The black onyx accents appreciate the same gentle treatment. Clean with a soft, dry or barely-damp cloth — no soaking. Solid 14K white gold holds its tone indefinitely and never needs replating; a soft jewelry cloth keeps it bright. Store the rings on their own so nothing scratches the starfield.
Frequently asked questions
What is galaxy sandstone / blue goldstone?
Galaxy sandstone, known to collectors as blue goldstone, is a deep midnight-blue artisan material packed with tiny copper crystals that sparkle like a field of stars. The craft behind it goes back centuries, and it's prized for one thing above all: a dense, cosmic shimmer that no natural stone reproduces. If you want the look of a galaxy on your finger, this is the material that does it best.
Why pair it with solid gold?
You get the best of both worlds. The solid 14K white gold construction is built to last a lifetime, never needs replating, and holds its value — a true heirloom setting. The galaxy sandstone center is chosen for its unmatched cosmic sparkle, the star of the show. If you'd prefer a natural or lab-grown gemstone center such as blue sapphire in this same solid gold design, message us for a custom quote.
What's the difference between this and the sterling silver version?
The design is identical (kite galaxy sandstone center, black onyx halo, chevron contour band with black onyx accents). The difference is the metal: this version is solid 14K white gold — built to last a lifetime, never needs replating, holds resale and inheritance value — versus the more accessible sterling silver version. Choose this version for the cosmic design in heirloom-tier solid gold.
Are the black accents real black diamonds?
The black accents are natural black onyx, a variety of chalcedony quartz. Most commercial black onyx is heat-treated for uniform black saturation, which is industry standard. The underlying material is real natural chalcedony quartz. On this solid gold version, the black onyx accents can be upgraded to black diamond on request — message us before ordering for a custom quote.
How durable is the ring for daily wear?
The solid 14K white gold setting is durable and built to last. The galaxy sandstone center, like many treasured collector stones, has a lustrous surface that stays at its best with gentle care — keep it away from hard knocks and harsh chemicals, and slip it off for activities where it might take impact. The black onyx accents appreciate the same gentle treatment. Cared for this way, the set stays brilliant for the long haul.
Is this ring solid gold or gold plated?
Solid 14K white gold throughout — no plating, no gold-filled construction, no sterling silver core, no rhodium finish layer. The entire ring is white gold alloy. Built to last a lifetime, never needs replating, holds resale and inheritance value.
How big is the center stone?
5.0 × 8.0 mm kite cut. The elongated kite shape (pointed at the bottom, angled at the top) gives the galaxy sandstone a large visible surface to show off the starfield sparkle, and the geometric shape adds to the celestial, crystalline aesthetic. With the black onyx halo framing it, the overall ring face reads larger than the center stone alone.
What does the design symbolize?
The set is built around the cosmic, starry-night aesthetic — the deep blue glittering sandstone as the "galaxy" or night sky, the black onyx as the surrounding dark cosmos. It's inspired by the Great Rift of the Milky Way. For buyers who love astronomy, the cosmos, or the boundless wonder of the night sky, the design carries that celestial symbolism. The kite geometry adds a modern, crystalline structure to the cosmic theme.
Can I get this in yellow or rose gold, or 18K?
Yes — available in solid 14K white gold (this listing default), 14K yellow gold, or 14K rose gold on request. 18K upgrades (white, yellow, or rose) are available at additional cost. White gold preserves the cool cosmic palette; yellow or rose gold would give a warmer contrast against the deep blue galaxy stone. Message us before ordering.
Do you offer this design with a natural stone center?
Yes — message us before ordering. We can quote a version with a lab-grown blue sapphire or other natural/lab-grown stone center in this same solid gold celestial design. The galaxy sandstone is the signature material for the starry-night effect, but a natural or lab-grown gemstone center is available for buyers who want an all-gemstone solid gold piece.
What's included in the set?
Two rings: the kite galaxy sandstone engagement ring with black onyx halo, and the matching chevron contour band with black onyx accents. Both are solid 14K white gold, and they ship together in a free luxury velvet jewelry box.
What's included in the box?
Both rings, a free luxury velvet jewelry box, and a care card. Free USA shipping.
