Rising Gemstone Investment in 2025

Market Performance, Trends, and Outlook for Modern Collectors & Investors

by Gemological Identification Laboratory

The global coloured gemstone market in 2025 continues its strong upward trajectory, driven by shifting luxury consumer preferences, scarcity of high-quality stones, and increased demand for transparent, responsibly sourced gems.

While traditional jewellery categories saw moderate growth, investment-grade gemstones — especially ruby, sapphire, emerald, spinel, Paraíba tourmaline, and rare collector stones — significantly outperformed most luxury assets.

Across auctions, private sales, and dealer markets, select high-quality gems appreciated between 8% and 22% year-on-year.

Market Overview (2024-2025)

Overall performance

• Jewellery market growth (general): +3–4%

• Coloured gemstone investment segment: +12–18%

• Ultra-rare gemstones (Kashmir sapphire, Burmese ruby, Colombian emerald): +20%

The outperformance is driven by:

• Rising global wealth (Asia, Middle East, North America)

• Declining availability of major mines

• A strong shift from “branded jewellery” to “intrinsic value assets”

• Record auction results in late 2024 and early 2025

Consumer behaviour has also evolved: buyers now see coloured gemstones as portable, appreciating stores of value — similar to fine art or vintage watches.

Emerging Trends in 2025
