About this 1.02ct natural oval diamond

This 1.02ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2394151398. Listed at 14 retailers as of October 30, 2026, with prices from £1,033 to £2,719, a £1,686 spread on the same certified stone. NZ Jewellers lists it at £2,719. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
