About this 1.15ct natural marquise diamond

This 1.15ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 15602789. Listed at 4 retailers as of November 2, 2026, with prices from $15,419 to $19,621, a $4,201 spread on the same certified stone. MOH London lists it at $19,621. 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.
