About this 1.3ct lab-grown round diamond

This 1.3ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG455034214 or 455034214. Listed at 12 retailers as of November 5, 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.
