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 LG786621603 or 786621603. Listed at 16 retailers as of November 5, 2026, with prices from $483 to $2,041, a $1,558 spread on the same certified stone. MOH London lists it at $2,041. 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.
