About this 0.74ct natural marquise diamond

This 0.74ct natural marquise sits in the half to three-quarter 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 5191838766. Listed at 6 retailers as of November 5, 2026, with prices from $1,717 to $2,590, a $873 spread on the same certified stone. 77 Diamonds lists it at $2,590. 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.
