This 0.8ct natural cushion sits in the just-under-one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 7 retailers as of November 1, 2026, with prices from $2,008 to $4,251, a $2,243 spread on the same certified stone. Diamond Exchange Canada lists it at $4,251. 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.
