This 1.51ct lab-grown round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG445039438 or 445039438. Listed at 11 retailers as of October 27, 2026, with prices from $1,140 to $4,613, a $3,473 spread on the same certified stone. MOH London lists it at $4,613. 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.
