About this 3.03ct lab-grown marquise diamond

This 3.03ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG749586337 or 749586337. Listed at 7 retailers as of November 1, 2026, with prices from $433 to $2,830, a $2,397 spread on the same certified stone. Frank Darling lists it at $2,830. 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.
