About this 1.5ct lab-grown oval diamond

This 1.5ct lab-grown oval 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 LG747523265 or 747523265. Listed at 6 retailers as of October 26, 2026, with prices from $426 to $1,148, a $722 spread on the same certified stone. MOH London lists it at $1,148. 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.
