About this 1.01ct lab-grown round diamond

This 1.01ct lab-grown round sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG472172676 or 472172676. Listed at 10 retailers as of November 4, 2026, with a 138% 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.
