About this 0.81ct natural oval diamond

This 0.81ct natural oval sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6525527751. Listed at 12 retailers as of October 31, 2026, with prices from £938 to £1,420, a £482 spread on the same certified stone. GemTrove lists it at £1,420. 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.
