About this 1.71ct natural marquise diamond

This 1.71ct natural marquise sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6562325157. Listed at 5 retailers as of November 4, 2026, with prices from $7,842 to $9,405, a $1,563 spread on the same certified stone. Brilliance lists it at $9,405. 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.
