This 1.43ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LGG1201808. Listed at 7 retailers as of October 29, 2026, with prices from $516 to $2,325, a $1,808 spread on the same certified stone. Taylor and Hart lists it at $2,325. 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.
