About this 1.02ct natural oval diamond

This 1.02ct natural oval sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231127593. Listed at 17 retailers as of November 5, 2026, with prices from £2,495 to £5,515, a £3,021 spread on the same certified stone. NZ Jewellers lists it at £5,515. 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.
