A sapphire valuation establishes whether the stone is natural or synthetic, possible treatments (commonly heating) and quality characteristics: colour, clarity, cut and weight. These support the market valuation. An HRD Antwerp accredited gemmologist performs the examination.
Sapphire is among the most sought-after gemstones. Its value depends strongly on identity, colour and treatments. Synthetic and heavily treated sapphires are common in the market.
What we examine
- Whether the sapphire is natural or synthetic;
- Treatments such as heating or diffusion that affect value;
- Quality: colour, clarity, cut and carat weight.
