The Gemports Transaction Index (GTI) serves as the benchmark for the colored gemstone market, specifically tracking Ruby and Sapphire activity. Far beyond a simple price tracker, its methodology deeply integrates market transaction data by rigorously factoring in price movement and trade volume across key characteristics like size, quality, treatment and origin. This makes the GTI an essential and powerful tool for industry stakeholders, providing a holistic outlook on market trends, liquidity, and stone availability for planning and investment.
