This 1.45ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG790621867 or 790621867. Listed at 14 retailers as of November 2, 2026, with prices from $397 to $2,320, a $1,923 spread on the same certified stone. Do Amore Diamonds lists it at $2,320. 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.
