Glass vs Goldstone
Glass and Goldstone are easy to confuse because both are materials. Both sit near Mohs 5.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Glass and Goldstone
- Both sit near Mohs 5.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Hold a thin edge to the light: Glass is translucent, Goldstone is opaque.
- They overlap in brown, but Glass also comes in green, clear, and blue and Goldstone also comes in orange and yellow.
Glass vs Goldstone properties
| Property | Glass | Goldstone |
|---|---|---|
| Type | Materials | Materials |
| Mohs hardness | 5.5 | 5.5 |
| Luster | vitreous | vitreous |
| Streak | White to colorless | White to colorless |
| Transparency | translucent | opaque |
| Specific gravity | 2.5 | 2.5 |
| Crystal system | amorphous | amorphous |
| Common colors | Green, Brown, Clear, Blue, White, Frosted | Copper, Brown, Orange, Gold, Sparkly |
| Rarity | common | common |
| Typical specimen value | $1–$40+ | $3–$80+ |
Which is more valuable?
Goldstone is usually the more valuable of the two: a typical collector specimen runs about $15 against $5 for Glass, and premium Goldstone can reach $80 or more.
About Glass
Glass is a man-made amorphous material. Surf-tumbled sea glass and weathered bottle shards are among the most common glassy finds mistaken for natural minerals.
About Goldstone
Goldstone is a manufactured glittering glass, usually coppery brown to orange, sold as beads, cabochons, and tumbled stones.
Glass vs Goldstone FAQ
