Frequently asked questions

• Is goldstone a natural gemstone?

  No. Goldstone is a man-made glass, not a mineral. It's produced by suspending copper particles (for the classic reddish-brown variety) or cobalt and other metal oxides (for blue and green varieties) in molten glass under controlled conditions, then cooling slowly so the metal crystallizes into the sparkling flecks you see. The material has been made in Italy since the 17th century and is now also produced in China. Because it's synthetic, every strand is essentially treated by definition — the sparkle is structural to the glass itself, not a coating that can wear off.
• How does goldstone hold up in finished jewelry?

  Goldstone is glass at roughly Mohs 5.5, so it's durable enough for most stringing applications but behaves like glass on impact — it can chip or fracture if knocked against a hard surface or another bead. It works well in earrings, necklaces, and bracelets that don't take heavy abuse. For rings or cuff-style bracelets that bang around, choose a harder material. The polished surface holds its shine indefinitely since the sparkle comes from internal copper or cobalt particles, not a surface treatment that could wear.
• How do I tell goldstone apart from sunstone or aventurine?

  Sunstone is a natural feldspar with metallic schiller from hematite or copper platelets — the flecks are irregular, oriented along cleavage planes, and the body color is warmer and less uniform. Aventurine is quartz with mica or fuchsite inclusions giving a softer shimmer, not the sharp metallic sparkle of goldstone. Goldstone's flecks are perfectly uniform hexagonal copper crystals distributed evenly through clear or tinted glass — too regular to be natural. Under magnification, you'll often see small gas bubbles in goldstone, a dead giveaway for glass.
• What projects does goldstone work well in?

  Goldstone reads as a warm metallic accent, so it pairs naturally with copper, bronze, and antiqued brass findings, and with stones in the brown-red-orange range like carnelian, tiger eye, and red jasper. Blue goldstone plays well with sterling, hematite, and lapis or sodalite for a night-sky palette. Smaller sizes (4mm, 6mm) work as spacers between larger feature stones; 8–12mm rounds carry well as the main bead in earrings or statement strands. The high sparkle reads best against matte or oxidized metals rather than competing with bright polish.
• How should I clean goldstone beads?

  Mild soap, lukewarm water, and a soft cloth. Avoid ultrasonic cleaners — the vibration can stress glass and potentially crack beads, especially if there are any existing micro-fractures from drilling. Skip steam cleaners and harsh solvents. Goldstone doesn't react with normal skin oils or sweat, so routine wipe-downs after wear are usually all that's needed. Store separately from harder stones (quartz, topaz, corundum) that could scratch the polished glass surface in a shared bead box or jewelry roll.
