This 1.3ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG800608725 or 800608725. Listed at 2 retailers as of November 2, 2026, with prices from $519 to $958, a $439 spread on the same certified stone. Diamond Wish lists it at $958. 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.
