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 IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7551785389. Listed at 5 retailers as of November 5, 2026, with prices from $3,405 to $4,051, a $646 spread on the same certified stone. Blue Nile lists it at $4,051. 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.
