About this 0.3ct natural oval diamond

This 0.3ct natural oval sits in the sub-half-carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5242070620. Listed at 9 retailers as of October 27, 2026, with prices from £234 to £450, a £216 spread on the same certified stone. Moon Ocean lists it at £450. 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.
