About this 0.25ct natural round diamond

This 0.25ct natural round sits in the sub-half-carat band, graded J colour (near-colourless) and I1 clarity (included), with a very-good cut grade and certified by GIA 1259515559. Listed at 9 retailers as of October 31, 2026, with a 112% 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.
