About this 0.33ct natural marquise diamond

This 0.33ct natural marquise sits in the sub-half-carat band, graded E 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 6551626423. Listed at 18 retailers as of October 29, 2026, with prices from £197 to £637, a £440 spread on the same certified stone. MOH London lists it at £637. 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.
