This 4.1ct lab-grown heart sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG750587152 or 750587152. Listed at 15 retailers as of November 6, 2026, with prices from $1,055 to $5,827, a $4,771 spread on the same certified stone. Brilliant Earth lists it at $5,827. 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.
