About this 51.16ct lab-grown heart diamond

This 51.16ct lab-grown heart sits in the over five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG782614867 or 782614867. Listed at 4 retailers as of October 26, 2026, with a relatively tight 1% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
