Expert Opinion

Ahmed Shareek's Assessment

"Heat treatment is standard practice for the great majority of blue sapphire on the market, including fine Ceylon material, and it has been accepted trade-wide for generations. What matters is honest disclosure, and this stone's treatment is stated plainly. At 0.87 carats with a clean, well-cut round shape and genuinely intense Ceylon blue color, it's an easy stone to recommend for its price point."

Good to Know

Match the report to the stone: confirm its weight and measurements against the stone you receive, and keep the document with it.
Heat treatment is disclosed — the standard route for this colour, not a mark against the stone.
Origin is our own sourcing record (Sri Lanka / Ceylon), not a lab finding.
Sized for an accent or smaller centre. See it first via Try Before You Buy.
