About this 1.02ct natural oval diamond

This 1.02ct natural oval sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2537875828. Listed at 16 retailers as of November 2, 2026, with prices from $3,862 to $10,266, a $6,404 spread on the same certified stone. NZ Jewellers lists it at $10,266. 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.
