About this 2.08ct lab-grown round diamond

This 2.08ct lab-grown round sits in the two to three carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG678584378 or 678584378. Listed at 19 retailers as of November 4, 2026, with a 343% 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.
