This 1.5ct lab-grown round 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 LG425067191 or 425067191. Listed at 11 retailers as of November 2, 2026, with prices from $1,087 to $5,852, a $4,765 spread on the same certified stone. MOH London lists it at $5,852. 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.
