About this 0.3ct natural oval diamond

This 0.3ct natural oval sits in the sub-half-carat band, graded H 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 1553636150. Listed at 17 retailers as of October 30, 2026, with prices from £243 to £591, a £349 spread on the same certified stone. MOH London lists it at £591. 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.
