This 0.73ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840620849 or 840620849. Listed at 16 retailers as of October 30, 2026, with prices from $387 to $2,217, a $1,831 spread on the same certified stone. Reve Diamonds lists it at $2,217. 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.
