This 0.9ct natural heart 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 2546177356. Listed at 12 retailers as of October 30, 2026, with prices from £628 to £2,208, a £1,579 spread on the same certified stone. NZ Jewellers lists it at £2,208. 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.
