An oval lab-created blue sandstone (blue goldstone) centre stone flanked by two pear-cut lab-created alexandrite side stones, with brilliant-cut accent stones — handcrafted in Jaipur in 925 sterling silver, yellow plated, or rose plated. The blue sandstone is a glass-matrix material infused with uniformly distributed metallic copper crystals that produce an omnidirectional sparkle across the stone’s face, mimicking a starlit sky; the sparkle is consistent and even across the oval face. The lab alexandrite side stones shift from teal-blue to green in daylight to purplish-red in incandescent light. The combination of the static midnight sparkle of the sandstone centre and the colour-shifting alexandrite sides creates an unusual two-layer light dynamic: the sandstone glitters consistently in all light; the alexandrite changes colour with the light source.

⚠️ Note before publishing: The description references “22k yellow gold plating.” 22k plating is an unusually high karat claim for plated jewelry (most commercial plated jewelry uses 14k or 18k flash plating). Verify the exact plating specification with your supplier before publishing. If confirmed as 22k, retain the claim and it becomes a strong differentiator. If not confirmed, update to the correct karat or remove the karat claim and describe as “gold colour plating.” The placeholder below uses “gold plated” without a karat until confirmed.

Stone Details

• Centre Stone: Lab-created blue sandstone (blue goldstone) — oval cut; prong or bezel set [confirm setting type]; deep midnight blue with metallic copper crystal inclusions producing omnidirectional sparkle; a glass-matrix material, not a mineral gemstone
• Blue Sandstone / Blue Goldstone: A man-made glass material produced by melting silica glass with copper compounds under controlled reducing conditions; the copper crystallises within the glass matrix as uniformly distributed metallic crystals (typically cuprite or copper metal) that produce the characteristic sparkle; it is not a natural mineral; the name “goldstone” or “sandstone” is a traditional trade name for this glass product; lab-created is an accurate disclosure for this material as it is entirely manufactured; the midnight blue colour is produced by adding cobalt or other colourants to the glass melt
• Side Stones: Lab-created alexandrite (synthetic chrysoberyl, BeAl₂O₄ with vanadium) — pear cut; prong set; colour-change: teal-blue to green in daylight → purplish-red in incandescent light; Mohs 8.5
• Accent Stones: Brilliant-cut accent crystals along the band/setting shoulders
• Lab Alexandrite: Czochralski-grown synthetic chrysoberyl; same chemical composition and colour-change mechanism as natural alexandrite; commercially produced and a legitimate lab-created gemstone disclosure; colour change produced by vanadium absorbing in the yellow-green region of the visible spectrum

Ring Details

• Style: Vintage celestial cluster ring — anniversary ring, promise ring, statement ring
• Metal: 925 sterling silver, yellow plated, or rose plated (select above) — see metal notes below; gold plating karat to be confirmed with supplier (see note above)
• Band: Cluster-style setting with oval sandstone centre, pear alexandrite side stones, and accent crystal shoulders; vintage-inspired silhouette; elevated centre stone profile
• Hypoallergenic & nickel-free base
• Ring Sizes: US/CA 3–10 (custom sizes on request)

About Blue Sandstone

Blue sandstone (blue goldstone) is a fully man-made glass product, not a naturally occurring mineral. It is produced by melting silica glass with copper compounds in a reducing atmosphere, which causes copper to crystallise within the glass matrix as tiny metallic crystals. These crystals are uniformly distributed through the glass, producing the characteristic all-over sparkle that distinguishes goldstone from other glass materials. The deep midnight blue colour is achieved by adding cobalt oxide or similar colourants to the glass melt before the copper crystallisation occurs. The result is a material that genuinely resembles a slice of the night sky: a deep blue ground shot through with evenly distributed points of metallic light. The sparkle in blue sandstone is static — it glitters in the same pattern from all angles and under all lighting conditions — which is a different optical behaviour from alexandrite’s colour change or opal’s play-of-colour, both of which respond dynamically to viewing angle or light source. In this ring, the static sparkle of the sandstone centre and the dynamic colour shift of the alexandrite sides create two distinct light phenomena operating simultaneously.

Available Metals

• 925 Sterling Silver — may tarnish with moisture; restore with a silver polishing cloth; the cool silver tone creates a high-contrast setting for the midnight blue sandstone
• Yellow Plated — 925 sterling silver base with gold colour plating [karat to confirm]; warm tone; pairs naturally with the celestial aesthetic; plating may wear with friction and moisture; keep dry to extend plating life
• Rose Plated — 925 sterling silver base with rose gold colour plating; plating may wear with friction and moisture; keep dry to extend plating life

Care Instructions

• Remove before swimming, showering, or applying lotions, perfumes, or hand sanitisers
• Avoid ultrasonic cleaners and harsh chemical dips — these can damage the plating and the glass sandstone surface
• Wipe gently with a soft non-abrasive microfibre cloth after wearing
• Alexandrite (Mohs 8.5) is durable; blue sandstone (glass) is softer — avoid impact on the centre stone
• Plated options: Keep dry to extend plating life; store in a sealed anti-tarnish pouch
• Store separately in a padded box or pouch

Frequently Asked Questions

• What is blue sandstone? A man-made glass material (also called blue goldstone) with uniformly distributed metallic copper crystals that produce an all-over starlit sparkle effect; not a natural mineral.
• Do the alexandrite side stones really change colour? Yes — lab alexandrite is a genuine colour-change stone (synthetic chrysoberyl); teal-blue to green in daylight, purplish-red in incandescent light.
• Is the ring solid gold? No — 925 sterling silver base with gold colour plating; not solid gold; solid gold options may be available on request.
• Can I wear this every day? Yes with care — remove before water exposure, heavy activity, and chemical contact to protect the plating and the glass centre stone.
• Can I get a custom size? Yes — message us before ordering.
