This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 843696740. Listed at 16 retailers as of October 30, 2026, with prices from €3,782 to €8,205, a €4,423 spread on the same certified stone. NZ Jewellers lists it at €8,205. 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.
