About this 0.31ct natural oval diamond

This 0.31ct natural oval sits in the sub-half-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 815637806. Listed at 13 retailers as of October 29, 2026, with a relatively tight 24% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
