About this 1.01ct natural marquise diamond

This 1.01ct natural marquise sits in the classic one-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 819640039. Listed at 2 retailers as of October 31, 2026, with prices from $3,992 to $5,320, a $1,328 spread on the same certified stone. Yorxs lists it at $5,320. 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.
