This 1.53ct lab-grown heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG425067495 or 425067495. Listed at 10 retailers as of November 5, 2026, with prices from $1,569 to $7,620, a $6,050 spread on the same certified stone. MOH London lists it at $7,620. 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.
