About this 1.02ct lab-grown heart diamond

This 1.02ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG844657987 or 844657987. Listed at 12 retailers as of November 6, 2026, with prices from $228 to $1,266, a $1,038 spread on the same certified stone. Brilliant Earth lists it at $1,266. 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.
