Market evolution: Rubies sapphires emeralds (CN 710391) — 2015–2025
Introduction
This report examines the trade dynamics of the European Union in worked rubies, sapphires, and emeralds (customs code 710391) over the 2015–2025 period. The EU market for these precious stones is characterized by its high value, significant external trade dependency, and pronounced volatility. Over the decade, the bloc has experienced substantial growth in both imports and exports, but this expansion has been uneven, leading to a deepening trade deficit. This analysis will explore the key structural shifts, the evolution of trading partners, and the underlying vulnerabilities that define the EU's position in this global market.
1. Surging Values, Deepening Deficit: The EU's Growing Appetite
The EU's trade in precious coloured gemstones has expanded significantly in value over the period, with both imports and exports growing substantially. However, import growth has consistently outpaced export growth, resulting in a widening trade deficit.
- Robust Growth in Trade Flows: From 2015 to 2025, EU imports in value rose by 48.0%, from €433 million to €641 million. Exports also grew, increasing by 37.4% from €256 million to €352 million (General Overview).
- A Widening Trade Deficit: The structural imbalance is clear. The EU's trade deficit in this category expanded from -€177 million in 2015 to -€289 million in 2025, a deterioration of 63.4%. This indicates that the EU's internal consumption and processing activity increasingly relies on imported raw and semi-processed gemstones.
- Volume vs. Value Divergence: The physical quantity of imports and exports grew even faster than their value. Import volume (in tonnes) increased by 256.9%, while export volume grew by 158.7%. Simultaneously, the average price per tonne for both flows declined, by 32.0% for imports and 3.0% for exports. This suggests a potential shift in the product mix or grades being traded, or increased competitive pressure on pricing.
2. Shifting Partnerships and Internal Specialization
The landscape of the EU's key trading partners has evolved, and internal specialization among Member States has become more pronounced, with a few nations dominating the trade.
Evolution of Key External Partners:
| Flow | Partner | 2015 Value (€) | 2025 Value (€) | Change | Interpretation |
|---|---|---|---|---|---|
| Import | India | 50.1 M | 115.5 M | +130.5% | Emerged as the dominant supplier, nearly doubling its share. |
| Import | Madagascar | 3.9 M | 22.9 M | +482.5% | A major new or expanded source of supply. |
| Export | United States | 14.0 M | 79.9 M | +470.5% | Became the primary extra-EU destination for EU exports. |
| Export | Hong Kong | 28.1 M | 70.9 M | +152.4% | Reinforced its role as a key gateway to Asian markets. |
| Export | United Kingdom | 27.4 M | 5.5 M | -79.9% | The steepest decline among top partners, likely linked to Brexit. |

Internal EU Market Structure:
The trade is highly concentrated within the EU. In 2025, France and Italy alone accounted for €301 million (56%) of all EU imports and €299 million (85%) of all EU exports (Top Reporters by Value). This indicates their central role as processing and trading hubs. Specialization indices confirm this: Belgium and France show the highest Revealed Symmetric Comparative Advantage (RSCA), signifying a strong specialization in this product relative to their overall trade. In contrast, large economies like Italy and the Netherlands are net importers without a strong specialization (Market Structure).
3. High Volatility and Rising Vulnerability
The market is subject to significant price and volume shocks, and the EU's growing import dependence has increased its vulnerability to external supply disruptions.
- Pronounced Price Volatility: The trade flows exhibit high coefficients of variation (CV), indicating instability. For exports, shipments to Israel (CV: 2.57) and Switzerland (CV: 2.20) were particularly volatile. For imports, flows from Brazil (CV: 1.77) and Colombia (CV: 1.77) showed the highest instability (Volatility Bars).
- Major Price Shocks: Specific events stand out. The most severe detected shock was a 267.2% price increase for EU imports from the United States in 2018. A massive 1,730.4% price spike in exports to Switzerland occurred in 2019. These events, flagged as abnormal, highlight the market's sensitivity to sudden shifts in demand or supply chain disruptions (Top Shock Events).
- Deepening Import Dependency: The EU's net import reliance has shifted dramatically. It moved from a position of net reliance of -35.2% in 2015 (indicating a net exporter position) to 65.1% in 2025. This metric confirms the bloc's transition to a heavy net importer, making its downstream jewellery and gem industries more exposed to global supply and price risks (Net Import Reliance).
Conclusion
Between 2015 and 2025, the EU market for rubies, sapphires, and emeralds grew significantly in scale but became more dependent on external suppliers. Trade value and volume expanded, led by a surge in imports from India and Madagascar and exports destined primarily for the United States and Hong Kong. This growth, however, has entrenched a structural trade deficit.
The market is internally concentrated, with France and Italy acting as the EU's main trading hubs and exhibiting the greatest specialization. The period was also marked by high volatility, with several severe price shocks underscoring the market's instability. Most critically, the EU's position shifted from being a modest net exporter to a substantial net importer, increasing its vulnerability to global supply chain fluctuations. Future stability in this sector will likely depend on the EU's ability to diversify its supply sources and manage the price risks inherent in this high-value, globally traded commodity.
