About this 0.31ct natural oval diamond

This 0.31ct natural oval sits in the sub-half-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1503980681. Listed at 21 retailers as of November 1, 2026, with prices from $360 to $968, a $608 spread on the same certified stone. MOH London lists it at $968. 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.
