Thailand Yellow Sapphire
Thailand is a major processing and treatment hub for yellow sapphire, supplying much of the market's heated, commercial-grade material.
Thai yellow sapphire is typically heat-treated to produce or intensify its color from lighter or included rough, making it an accessible and consistent choice for buyers who don't require unheated material. It represents a large share of the everyday jewelry market, though it's generally considered a less traditional choice than unheated Ceylon stones for strict astrological sourcing.
