About this 1.05ct lab-grown marquise diamond

This 1.05ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG835644925 or 835644925. Listed at 17 retailers as of October 27, 2026, with prices from $342 to $1,050, a $708 spread on the same certified stone. Brilliant Earth lists it at $1,050. 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.
