This 1.48ct 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 LG840629991 or 840629991. Listed at 11 retailers as of October 29, 2026, with prices from $408 to $4,410, a $4,002 spread on the same certified stone. Brilliant Earth lists it at $4,410. 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.
