About this 2.5ct lab-grown round diamond

This 2.5ct lab-grown round sits in the two to three carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG480167781 or 480167781. Listed at 8 retailers as of November 4, 2026, with a 80% 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.
