Gemstone Investment: Which stones are increasing in value?

Gemstones as an Investment: What truly retains value

Gemstones as an investment are a complex topic. Most gemstones are not stable investment objects – but a select few have properties that make them valuable alternative stores of wealth.

What constitutes a gemstone investment

• Rarity: The rarer the origin, the more stable the value
• Certificate: Only with GIA, GRS, or Gübelin – no investment value without a certificate
• Untreated: Untreated stones with a certificate fetch many times more
• Size: Large stones over 3 carats are exponentially rarer

• Paraiba Tourmaline: Extremely rare, rising prices, growing demand from Asia
• Demantoid Garnet (Urals): Very rare, hard cut, limited mines
• Alexandrite: Color-changing gemstone – in demand and increasingly rare
• Sapphire (Kashmir, untreated): Hardly available anymore – prices doubled in 10 years

Honest Assessment

Gemstones as an investment can work – but only with very profound knowledge, long holding periods (10+ years), and the right dealer network. Without these prerequisites: gold jewelry or gold ETFs are more reliable.
