About this 1.2ct lab-grown round diamond

This 1.2ct lab-grown round sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG494166398 or 494166398. Listed at 14 retailers as of November 2, 2026, with prices from $574 to $2,296, a $1,722 spread on the same certified stone. MOH London lists it at $2,296. 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.
