About this 0.46ct natural marquise diamond

This 0.46ct natural marquise sits in the sub-half-carat band, graded J 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 2191030351. Listed at 5 retailers as of November 1, 2026, with prices from £339 to £709, a £370 spread on the same certified stone. 77 Diamonds lists it at £709. 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.
