This 1.21ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG833665776 or 833665776. Listed at 14 retailers as of October 30, 2026, with prices from $233 to $1,138, a $905 spread on the same certified stone. Reve Diamonds lists it at $1,138. 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.
