About this 1.8ct natural marquise diamond

This 1.8ct natural marquise sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 803680468. Listed at 15 retailers as of October 30, 2026, with prices from €10,344 to €16,833, a €6,489 spread on the same certified stone. NZ Jewellers lists it at €16,833. 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.
