About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 250000191596. Listed at a single retailer as of October 31, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
