This 1.2ct natural asscher sits in the classic one-carat band, graded I 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 3 retailers as of November 4, 2026, with prices from $3,451 to $4,401, a $950 spread on the same certified stone. Blue Nile lists it at $4,401. 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.
