About this 3ct natural marquise diamond

This 3ct natural marquise sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6541697657. Listed at 24 retailers as of November 4, 2026, with prices from £24,729 to £44,966, a £20,237 spread on the same certified stone. MOH London lists it at £44,966. 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.
