About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG768679349 or 768679349. Listed at 17 retailers as of October 25, 2026, with a 175% 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.
