Do Gemstones Really Increase in Value?
The short answer is: some do, but not all.
Diamonds are famous, but they are not always the rarest. Fine-quality colored gemstones such as rubies, sapphires, and emeralds are much harder to find, especially in larger sizes. Certain rare varieties like alexandrite, Paraiba tourmaline, and fine spinel can be even more valuable.
Key Factors That Influence Gem Value Over Time
- Rarity: Natural supply is limited by geology.
- Color: Rich, pure, vibrant hues always command the highest demand.
- Clarity & Transparency: Gems with fewer inclusions and good brilliance are more valuable.
- Size: Large stones multiply in price per carat as size increases.
- Origin: Famous origins (Burma ruby, Kashmir sapphire, Colombian emerald) boost collector interest.
- Treatment: Untreated stones are far more collectible than heavily treated or filled stones.
Gemstones That Often Appreciate
- Ruby, Sapphire, Emerald – the “Big Three,” especially when untreated and with reports from labs like GIA or SSEF.
- Spinel – fine reds, pinks, and cobalt blues are highly sought after.
- Alexandrite – rare color-changing gem, collectible in any size.
- Paraiba Tourmaline – neon blue/green stones are extremely scarce.
- Demantoid Garnet – rare green garnet, especially with horsetail inclusions.
Common Misconceptions
- “All gems automatically increase in value.” → Not true; only fine natural stones tend to appreciate.
- “Lab-grown has the same value as natural.” → Lab gems are great for affordability but not investments.
- “Bigger is always better.” → Quality matters more than size.
How to Choose Gems with Better Long-Term Value
- Focus on top quality over size.
- Look for natural and untreated stones with certificates.
- Learn about origins—certain mines are legendary.
- Buy timeless designs and excellent craftsmanship.
- Keep documentation and care records for provenance.
Final Thoughts
Yes, gemstones can increase in value over time, but it depends on quality, rarity, and demand. Collectors and investors often focus on fine ruby, sapphire, emerald, alexandrite, and Paraíba tourmaline because of their scarcity.
