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 $1,476 to $7,336, a $5,859 spread on the same certified stone. MOH London lists it at $7,336. 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.
