This 1.23ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG840665265 or 840665265. Listed at 13 retailers as of October 30, 2026, with prices from $346 to $1,635, a $1,289 spread on the same certified stone. Reve Diamonds lists it at $1,635. 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.
