About this 1.03ct lab-grown round diamond

This 1.03ct lab-grown round sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG846647387 or 846647387. Listed at 9 retailers as of November 1, 2026, with a 89% 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.
