This 1.55ct lab-grown heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816615975 or 816615975. Listed at 19 retailers as of October 27, 2026, with prices from $890 to $5,514, a $4,624 spread on the same certified stone. Brilliant Earth lists it at $5,514. 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.
