This 1.51ct lab-grown marquise sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG844687965 or 844687965. Listed at 9 retailers as of October 29, 2026, with prices from $263 to $991, a $728 spread on the same certified stone. Taylor and Hart lists it at $991. 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.
