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 LG526291318 or 526291318. Listed at 17 retailers as of October 29, 2026, with prices from $507 to $2,475, a $1,967 spread on the same certified stone. MOH London lists it at $2,475. 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.
