About this 1.18ct lab-grown marquise diamond

This 1.18ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG733574293 or 733574293. Listed at 18 retailers as of October 30, 2026, with prices from $307 to $2,277, a $1,970 spread on the same certified stone. Brilliant Earth lists it at $2,277. 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.
