About this 0.81ct natural oval diamond

This 0.81ct natural oval sits in the just-under-one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2564636616. Listed at 6 retailers as of November 1, 2026, with prices from £888 to £1,657, a £768 spread on the same certified stone. With Clarity lists it at £1,657. 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.
