This 1.38ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830622668 or 830622668. Listed at 20 retailers as of November 4, 2026, with prices from $607 to $3,680, a $3,073 spread on the same certified stone. Brilliant Earth lists it at $3,680. 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.
