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) and certified by IGI LG790605110 or 790605110. Listed at 18 retailers as of November 2, 2026, with prices from $257 to $2,290, a $2,033 spread on the same certified stone. Do Amore Diamonds lists it at $2,290. 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.
