About this 0.39ct natural oval diamond

This 0.39ct natural oval sits in the sub-half-carat band, graded J 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 7518745444. Listed at 17 retailers as of October 30, 2026, with prices from £166 to £869, a £703 spread on the same certified stone. NZ Jewellers lists it at £869. 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.
