About this 0.5ct natural round diamond

This 0.5ct natural round sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 6412184992. Listed at 22 retailers as of November 2, 2026, with a 216% 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.
