About this 1ct lab-grown heart diamond

This 1ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG497161164 or 497161164. Listed at 10 retailers as of November 6, 2026, with prices from $304 to $1,335, a $1,032 spread on the same certified stone. NZ Jewellers lists it at $1,335. 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.
