About this 1.5ct lab-grown round diamond

This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG803613712 or 803613712. Listed at 17 retailers as of November 5, 2026, with prices from $218 to $1,132, a $914 spread on the same certified stone. MOH London lists it at $1,132. 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.
