About this 1.01ct natural marquise diamond

This 1.01ct 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 2556263287. Listed at 10 retailers as of November 4, 2026, with prices from $2,180 to $5,008, a $2,828 spread on the same certified stone. MOH London lists it at $5,008. 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.
