This 1.57ct lab-grown heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG763605715 or 763605715. Listed at 25 retailers as of October 30, 2026, with prices from $1,163 to $6,520, a $5,357 spread on the same certified stone. Brilliant Earth lists it at $6,520. 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.
