About this 0.37ct natural round diamond

This 0.37ct natural round sits in the sub-half-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 1519700759. Listed at 21 retailers as of October 30, 2026, with a 547% 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.
