About this 0.31ct natural oval diamond

This 0.31ct natural oval sits in the sub-half-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566590323. Listed at 17 retailers as of October 26, 2026, with prices from £156 to £503, a £346 spread on the same certified stone. MOH London lists it at £503. 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.
