About this 0.5ct natural oval diamond

This 0.5ct natural oval sits in the half to three-quarter carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6521785807. Listed at 14 retailers as of October 30, 2026, with prices from £402 to £1,692, a £1,290 spread on the same certified stone. NZ Jewellers lists it at £1,692. 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.
