This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG483195466 or 483195466. Listed at 12 retailers as of November 5, 2026, with prices from $1,494 to $9,023, a $7,529 spread on the same certified stone. MOH London lists it at $9,023. 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.
