This 1.22ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG845615124 or 845615124. Listed at 12 retailers as of November 1, 2026, with prices from $215 to $1,146, a $931 spread on the same certified stone. Reve Diamonds lists it at $1,146. 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.
