About this 3.7ct lab-grown marquise diamond

This 3.7ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG807666110 or 807666110. Listed at 17 retailers as of October 31, 2026, with prices from €5,189 to €20,081, a €14,893 spread on the same certified stone. Taylor and Hart lists it at €20,081. 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.
