About this 4.25ct lab-grown heart diamond

This 4.25ct lab-grown heart sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI. Listed at 5 retailers as of October 28, 2026, with a relatively tight 7% 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.
