This 0.73ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825656607 or 825656607. Listed at 18 retailers as of November 4, 2026, with prices from $594 to $2,681, a $2,087 spread on the same certified stone. Reve Diamonds lists it at $2,681. 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.
