About this 1.42ct lab-grown heart diamond

This 1.42ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG763628410 or 763628410. Listed at 4 retailers as of October 29, 2026, with a 35% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
