About this 1.7ct natural marquise diamond

This 1.7ct 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 5242023104. Listed at 18 retailers as of October 30, 2026, with prices from $14,255 to $25,621, a $11,366 spread on the same certified stone. NZ Jewellers lists it at $25,621. 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.
