About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 2121693006. Listed at 26 retailers as of November 4, 2026, with a 79% 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.
