About this 1ct lab-grown heart diamond

This 1ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG835670073 or 835670073. Listed at 17 retailers as of October 30, 2026, with prices from $303 to $1,803, a $1,500 spread on the same certified stone. Brilliant Earth lists it at $1,803. 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.
