Gemstone Investment: Which stones are increasing in value?
Kurz gesagt:
Gemstones as an Investment: Burma Ruby, Paraiba & Alexandrite explained. Which stones retain their value – an honest assessment from Corelune.
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
Investment Stones 2026
- Burma Ruby (untreated, GRS): Continuous value appreciation for decades
- 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.
