About this 0.43ct natural oval diamond

This 0.43ct natural oval sits in the sub-half-carat band, graded G colour (near-colourless) and I1 clarity (included) and certified by IGI 510181998. Listed at 7 retailers as of October 31, 2026, with a 179% 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.
