This 1.43ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG618476014 or 618476014. Listed at 6 retailers as of November 2, 2026, with prices from $307 to $1,930, a $1,623 spread on the same certified stone. Do Amore Diamonds lists it at $1,930. 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.
