About this 1.2ct lab-grown round diamond

This 1.2ct lab-grown round sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG657424193 or 657424193. Listed at 21 retailers as of November 3, 2026, with prices from $167 to $970, a $803 spread on the same certified stone. Brilliant Earth lists it at $970. 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.
