About this 1.2ct lab-grown marquise diamond

This 1.2ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG793623510 or 793623510. Listed at 16 retailers as of November 4, 2026, with prices from $180 to $1,130, a $950 spread on the same certified stone. Reve Diamonds lists it at $1,130. 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.
