This 1.54ct 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 LG654473132 or 654473132. Listed at 11 retailers as of October 30, 2026, with prices from $619 to $5,676, a $5,057 spread on the same certified stone. Brilliant Earth lists it at $5,676. 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.
