This 0.78ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG692519969 or 692519969. Listed at 19 retailers as of November 5, 2026, with prices from $647 to $3,902, a $3,255 spread on the same certified stone. MOH London lists it at $3,902. 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.
