About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 811693452. Listed at 15 retailers as of October 30, 2026, with prices from $2,734 to $5,318, a $2,584 spread on the same certified stone. NZ Jewellers lists it at $5,318. 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.
