About this 1.31ct natural oval diamond

This 1.31ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and I1 clarity (included) and certified by GIA 5231866237. Listed at 3 retailers as of October 30, 2026, with a relatively tight 3% 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.
