About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded J 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 6441180371. Listed at 22 retailers as of November 5, 2026, with prices from £1,102 to £3,232, a £2,130 spread on the same certified stone. NZ Jewellers lists it at £3,232. 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.
