This 1.01ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG841643642 or 841643642. Listed at 22 retailers as of October 27, 2026, with prices from $245 to $1,340, a $1,095 spread on the same certified stone. Brilliant Earth lists it at $1,340. 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.
