About this 1.06ct lab-grown marquise diamond

This 1.06ct lab-grown marquise sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG787618073 or 787618073. Listed at 24 retailers as of October 30, 2026, with prices from $299 to $2,180, a $1,881 spread on the same certified stone. Brilliant Earth lists it at $2,180. 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.
