About this 1.01ct lab-grown round diamond

This 1.01ct lab-grown round sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG480150390 or 480150390. Listed at 11 retailers as of October 26, 2026, with a 312% 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.
