About this 0.4ct natural oval diamond

This 0.4ct natural oval sits in the sub-half-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5563227350. Listed at 4 retailers as of November 2, 2026, with prices from $491 to $653, a $162 spread on the same certified stone. 77 Diamonds lists it at $653. 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.
