About this 1.23ct natural oval diamond

This 1.23ct natural oval sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1519479701. Listed at 4 retailers as of October 29, 2026. 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.
