About this 1.7ct natural marquise diamond

This 1.7ct natural marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3545815336. Listed at 11 retailers as of November 2, 2026, with prices from $16,783 to $26,218, a $9,434 spread on the same certified stone. MOH London lists it at $26,218. 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.
