About this 0.7ct lab-grown round diamond

This 0.7ct lab-grown round sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG12450108 or 12450108. Listed at 3 retailers as of October 29, 2026, with prices from $246 to $886, a $640 spread on the same certified stone. MOH London lists it at $886. 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.
