About this 0.42ct natural marquise diamond

This 0.42ct natural marquise sits in the sub-half-carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6541986494. Listed at 5 retailers as of November 6, 2026, with prices from £363 to £487, a £124 spread on the same certified stone. 77 Diamonds lists it at £487. 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.
