About this 1.54ct natural marquise diamond

This 1.54ct natural marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2131419092. Listed at 3 retailers as of November 2, 2026, with prices from $24,888 to $36,052, a $11,163 spread on the same certified stone. MOH London lists it at $36,052. 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.
