About this 0.3ct natural oval diamond

This 0.3ct natural oval sits in the sub-half-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1558959229. Listed at 12 retailers as of October 29, 2026, with prices from $403 to $937, a $534 spread on the same certified stone. MOH London lists it at $937. 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.
