This 0.53ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG851645611 or 851645611. Listed at 5 retailers as of October 29, 2026, with prices from $658 to $1,286, a $628 spread on the same certified stone. Taylor and Hart lists it at $1,286. 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.
