This 1.71ct natural marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6562061209. Listed at 3 retailers as of November 1, 2026, with prices from $14,690 to $17,981, a $3,291 spread on the same certified stone. 77 Diamonds lists it at $17,981. 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.
