About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-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 1142863862. Listed at 7 retailers as of November 2, 2026, with prices from $3,785 to $7,340, a $3,556 spread on the same certified stone. MOH London lists it at $7,340. 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.
