About this 4.3ct lab-grown heart diamond

This 4.3ct lab-grown heart sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG594316336 or 594316336. Listed at 11 retailers as of October 31, 2026, with prices from €464 to €2,775, a €2,311 spread on the same certified stone. Brilliant Earth lists it at €2,775. 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.
