About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG729591187 or 729591187. Listed at 13 retailers as of October 25, 2026, with a 240% 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.
