About this 0.4ct natural oval diamond

This 0.4ct natural oval sits in the sub-half-carat band, graded H 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 5483913590. Listed at 10 retailers as of November 1, 2026, with prices from £401 to £818, a £417 spread on the same certified stone. MOH London lists it at £818. 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.
