About this 0.52ct lab-grown heart diamond

This 0.52ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840620856 or 840620856. Listed at 16 retailers as of October 30, 2026, with prices from $328 to $2,034, a $1,706 spread on the same certified stone. Reve Diamonds lists it at $2,034. 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.
