About this 0.8ct natural oval diamond

This 0.8ct natural oval sits in the just-under-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 2427011654. Listed at 25 retailers as of November 7, 2026, with prices from £752 to £2,574, a £1,822 spread on the same certified stone. NZ Jewellers lists it at £2,574. 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.
