This 0.9ct natural marquise sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6562502434. Listed at 5 retailers as of November 1, 2026, with prices from £920 to £1,076, a £156 spread on the same certified stone. Michael Trio lists it at £1,076. SI-grade stones are eye-clean roughly 60 to 70% of the time at this carat range. Check the inclusion plot on the cert and ask the retailer for high-resolution video before buying.
