About this 0.86ct lab-grown heart diamond

This 0.86ct lab-grown heart sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG524243283 or 524243283. Listed at 5 retailers as of October 29, 2026, with a 338% 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.
