About this 1.03ct natural marquise diamond

This 1.03ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5131528531. Listed at 5 retailers as of November 2, 2026, with prices from $10,946 to $16,354, a $5,408 spread on the same certified stone. MOH London lists it at $16,354. 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.
