This 1.01ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818658588 or 818658588. Listed at 19 retailers as of November 2, 2026, with prices from $567 to $3,594, a $3,027 spread on the same certified stone. Brilliant Earth lists it at $3,594. 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.
