This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG447099695 or 447099695. Listed at 11 retailers as of November 3, 2026, with prices from $1,186 to $5,891, a $4,705 spread on the same certified stone. MOH London lists it at $5,891. 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.
