This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2557666304. Listed at 4 retailers as of November 2, 2026, with prices from $7,311 to $9,086, a $1,774 spread on the same certified stone. GemTrove lists it at $9,086. 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.
