About the stone

Goldstone is a man-made glass, not a naturally occurring mineral, whose classic reddish-brown sparkle comes from tiny metallic copper crystals grown within the glass as it cools. Its development is traditionally credited to Vincenzo Miotti and the glassmakers of seventeenth-century Murano, Venice, Italy; its “locations” therefore refer to glassmaking centers rather than mining deposits. Also known as aventurine glass, avventurina, monk’s gold, monk’s stone, and gold flux, it inspired legends of monks accidentally spilling copper into molten glass—a charming but unsupported origin story. Modern crystal lore associates goldstone with ambition, confidence, motivation, and protection.

Mineral data

  • Chemical composition: Goldstone is a man-made glass, mainly silica with copper oxide, borax and other additives, filled with tiny crystals of metallic copper that give it a glittering effect; it is not a mineral and has no single formula.
  • Hardness: About 5.5 to 6 on the Mohs scale, as for most glass.
  • Color: Golden-brown to reddish brown with a glittering sheen of copper flecks.

Metaphysical data

Goldstone, recognized for its glittering, sunlike spark, has been utilized in metaphysical practices to inspire drive and vitality and to turn away unwanted energy.

Energizing and Protective Energy

  • It is thought to divert malevolent energy out of the body and into the Earth, where it can be dissipated safely.

Emotional Healing

Spiritual Growth

  • It is thought to remind the user that ambition feels best when grounded in gratitude, which is why it is called a sun stone.

Physical Healing

  • Goldstone is traditionally associated with comfort for arthritis and joint pain, though it is not a substitute for professional medical advice or treatment.
  • Some people wear it as a bracelet or keep it near, as a gentle reminder to move, stretch and seek care, always alongside, never instead of, qualified health care.

Care and handling

Goldstone is glass, so it can scratch, chip or crack if dropped or struck. Clean it with lukewarm water, mild soap and a soft cloth, then dry it. Avoid sudden temperature changes, harsh chemicals and ultrasonic cleaners. Because it is man-made glass containing copper, it should not be used in drinking water or elixirs, and a broken piece should be handled carefully.

Individual experiences with Goldstone vary, and its effects are personal. Approach it with a hopeful heart, use it mindfully to fuel your efforts, and trust your own intuition.
