About this 1.05ct lab-grown marquise diamond

This 1.05ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG846656612 or 846656612. Listed at 14 retailers as of October 24, 2026, with prices from $170 to $950, a $780 spread on the same certified stone. Brilliant Earth lists it at $950. 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.
