This 1.28ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831679993 or 831679993. Listed at 18 retailers as of October 29, 2026, with prices from $307 to $2,110, a $1,803 spread on the same certified stone. Brilliant Earth lists it at $2,110. 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.
