This 1.51ct lab-grown heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG849623570 or 849623570. Listed at 5 retailers as of October 31, 2026, with prices from $450 to $1,140, a $690 spread on the same certified stone. Taylor and Hart lists it at $1,140. 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.
