About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6243098972. Listed at 14 retailers as of November 5, 2026, with prices from $7,686 to $13,698, a $6,011 spread on the same certified stone. Wholesale Diamonds Direct lists it at $13,698. 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.
