About this 1.23ct natural marquise diamond

This 1.23ct natural marquise sits in the classic one-carat band, graded D 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 1545779760. Listed at 3 retailers as of November 6, 2026, with prices from $10,636 to $13,404, a $2,768 spread on the same certified stone. William & Sons Jewelers lists it at $13,404. 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.
