Goldstone Gemstone Beads

Frequently asked questions

• Is goldstone a real gemstone?

  No — goldstone is manmade glass, not a naturally occurring mineral. It is copper-bearing silica glass cooled under low-oxygen conditions so that tiny copper crystals precipitate and stay suspended in the cooled glass, producing the characteristic metallic sparkle. It has been included in the gemstone-bead catalog by trade convention since the 17th century, but mineralogically it is glass. Designers buy it for the sparkle effect that natural stones rarely produce.
• What is goldstone made of?

  Red / copper goldstone is silica glass with suspended copper crystals — the original recipe. Blue goldstone is silica glass with cobalt-and-manganese crystals. Green goldstone is silica glass with chromium-oxide crystals. Each color variant is a different glass chemistry rather than a tint or dye of a single base material. All three are manufactured under controlled low-oxygen conditions that let the metallic crystals form and remain suspended as the glass cools.
• Where does goldstone come from?

  Goldstone was invented in the 17th century in Venice, traditionally attributed to the Miotti family working the Murano glassmaking tradition. Italian Murano-tradition goldstone is still made today and represents the historical provenance tier. Chinese mass-production goldstone is the contemporary commodity tier and accounts for most current market supply. Dakota's active catalog includes both Italian and Chinese-sourced material; origin should be disclosed — ask before buying if it isn't specified.
• What's the difference between goldstone, sunstone, and aventurine?

  Goldstone is manmade glass with suspended metallic crystals. Sunstone is a natural feldspar with copper-platelet inclusions that produce a similar shimmer ("aventurescence"); it is harder (Mohs 6–6.5) and trades at a higher price tier. Aventurine is a natural quartzite (Mohs 6.5–7) with mica or fuchsite inclusions producing sparkle. All three share a glittering visual effect, but only goldstone is manufactured. "Blue sandstone" and "blue sunstone" labels on inexpensive strands are almost always blue goldstone sold under misleading nicknames.
• How durable is goldstone for daily wear?

  Mohs ~5.5 — typical of glass. Suitable for necklaces, earrings, and low-impact bracelet designs; less suited to rings or high-wear bracelet contexts where impact and abrasion are likely. Store goldstone separately from harder quartz-family stones to avoid surface scratches. Avoid ultrasonic and steam cleaning; clean with soft cloth and mild soap. The drilled-hole edges can chip under hard stringing tension, so use spacers and avoid knotting directly against the bead.
