About this 1.23ct natural oval diamond

This 1.23ct natural oval sits in the classic one-carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6515648288. Listed at 18 retailers as of November 4, 2026, with prices from £2,660 to £5,804, a £3,144 spread on the same certified stone. NZ Jewellers lists it at £5,804. 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.
