About this 1.73ct natural marquise diamond

This 1.73ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6545929772. Listed at 9 retailers as of November 2, 2026, with prices from $13,459 to $18,621, a $5,162 spread on the same certified stone. Jared lists it at $18,621. 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.
