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 VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG733574269 or 733574269. Listed at 17 retailers as of October 27, 2026, with prices from $185 to $1,640, a $1,455 spread on the same certified stone. Brilliant Earth lists it at $1,640. 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.
