About this 2.03ct natural marquise diamond

This 2.03ct natural marquise sits in the two to three 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 1246033322. Listed at 18 retailers as of November 6, 2026, with prices from $25,522 to $46,686, a $21,164 spread on the same certified stone. MOH London lists it at $46,686. 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.
