About this 4.52ct lab-grown heart diamond

This 4.52ct lab-grown heart sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG850605243 or 850605243. Listed at 7 retailers as of October 30, 2026, with prices from $1,415 to $5,240, a $3,825 spread on the same certified stone. With Clarity lists it at $5,240. 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.
