About this 1.03ct lab-grown heart diamond

This 1.03ct 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 LG825667206 or 825667206. Listed at 20 retailers as of November 3, 2026, with prices from $537 to $3,463, a $2,926 spread on the same certified stone. Brilliant Earth lists it at $3,463. 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.
