About this 0.31ct natural oval diamond

This 0.31ct natural oval sits in the sub-half-carat band, graded I colour (near-colourless) and I1 clarity (included), with a very-good cut grade and certified by IGI 713504109. Listed at 10 retailers as of October 29, 2026, with a 99% 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.
