This 1.3ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2546670029. Listed at 4 retailers as of November 6, 2026, with prices from $5,670 to $7,126, a $1,456 spread on the same certified stone. 77 Diamonds lists it at $7,126. 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.
