This 1.51ct lab-grown round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG442067251 or 442067251. Listed at 11 retailers as of October 29, 2026, with prices from $1,187 to $6,117, a $4,930 spread on the same certified stone. MOH London lists it at $6,117. 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.
