About this 0.42ct natural marquise diamond

This 0.42ct natural marquise sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7506775927. Listed at 5 retailers as of November 3, 2026, with prices from £430 to £929, a £499 spread on the same certified stone. Fonder Diamond lists it at £929. 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.
