About this 1.2ct lab-grown round diamond

This 1.2ct lab-grown round sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG800681231 or 800681231. Listed at 5 retailers as of November 2, 2026, with prices from $507 to $1,341, a $834 spread on the same certified stone. MOH London lists it at $1,341. 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.
