This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG526291313 or 526291313. Listed at 18 retailers as of October 26, 2026, with prices from $399 to $1,728, a $1,329 spread on the same certified stone. MOH London lists it at $1,728. 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.
