GEMSTONE MARKET OUTLOOK 2025

The fine gemstone market from 2020 to 2025 showed a clear bifurcation: the top tier of the market (GRS-certified, unheated, premier origin stones) appreciated substantially, while the commercial middle market was more mixed, affected by supply chain disruptions and changing retail demand patterns.

The most striking trend is the outperformance of the fine colored stone market versus diamonds. Lab-grown diamond technology has created deflationary pressure on natural diamond prices at the commercial level. Natural colored stones — which cannot be laboratory grown with equivalent optical quality at scale — have benefited from this contrast.

Asian wealth expansion. The growth of high-net-worth individuals in China, Singapore, Vietnam, India, and the Middle East has dramatically expanded the buyer base for fine colored stones. Asian collectors have strong cultural preferences for rubies, sapphires, and jade — and the scale of new buyers entering the market since 2010 has been a structural demand shift, not a temporary trend.

Inflation hedge demand. High-net-worth investors globally have increased allocations to tangible assets — art, wine, real estate, and gemstones — as a hedge against currency debasement and inflation. Gemstones, with their permanent supply constraints and global portability, fit this role well.

Alternative engagement ring demand.The decline of the diamond engagement ring as the default choice has accelerated colored stone demand from the jewelry buyer market. Sapphires, rubies, and spinels are increasingly sought for engagement rings, expanding the commercial buyer base for quality gemstones.

Certification and transparency.The growth of GRS certification awareness globally has made it easier for buyers to transact with confidence across borders. This reduction in information asymmetry has expanded the market and reduced the discount that buyers historically demanded for uncertainty.

Supply from premier gemstone origins is either declining, constrained by government export restrictions, or permanently limited. This is the structural foundation of the investment thesis:

• KASHMIR SAPPHIRESNo new production since the early 20th century. Supply is permanently fixed at historical output.
• BURMA SAPPHIRES AND RUBIESExport restrictions, political instability, and declining reserves constrain supply. US sanctions on Myanmar further complicate trade.
• MAHENGE SPINELSmall deposit with declining productivity. Recent production estimates suggest supply will diminish significantly within 5–10 years.
• COLOMBIAN EMERALDSMature mines with declining high-quality production. Environmental restrictions increasingly constrain operations.
• RUSSIAN ALEXANDRITEExhausted deposit. All Russian alexandrite in the market comes from historical stock.

Based on structural demand and supply trends, the 5-year outlook for the fine colored stone market is broadly positive, with some category-specific nuance:

The most important trend to watch is the potential for lab-grown colored stones (already available for sapphire and ruby) to eventually compete with the commercial middle market. Lab-grown stones cannot replicate the provenance, natural origin, and GRS certification that drive investment-grade value — but they may suppress prices in the $500–$3,000/ct range where uncertified commercial stones trade.

The market outlook strongly favors position concentration in investment-grade, certified, rare-origin material over commercial-grade stones. The gap in outlook between "GRS certified, unheated, Kashmir/Burma/Mogok Mahenge" and "heated, uncertified, commercial" is widening — structurally, not cyclically.

For the long-term investor, the five-year view supports maintaining positions in certified premium material, holding through the inherent illiquidity, and exiting through auction when market conditions are favorable. Timing within a 5-year window matters less than quality selection.
