About this 0.8ct natural oval diamond

This 0.8ct natural oval sits in the just-under-one-carat band, graded I 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 6555832789. Listed at 12 retailers as of November 4, 2026, with prices from £629 to £1,127, a £498 spread on the same certified stone. Helzberg Diamonds lists it at £1,127. 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.
