This 15.5ct lab-grown heart sits in the over five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG821674953 or 821674953. Listed at 6 retailers as of October 31, 2026, with prices from $15,447 to $44,770, a $29,324 spread on the same certified stone. Brilliant Earth lists it at $44,770. 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.
