About this 1.51ct natural marquise diamond

This 1.51ct 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 841646172. Listed at 16 retailers as of October 30, 2026, with prices from €5,909 to €11,334, a €5,424 spread on the same certified stone. NZ Jewellers lists it at €11,334. 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.
