About this 0.51ct natural radiant diamond

This 0.51ct natural radiant sits in the half to three-quarter carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2546749596. Listed at 11 retailers as of November 6, 2026, with a 71% 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.
