About this 0.4ct natural oval diamond

This 0.4ct natural oval sits in the sub-half-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557737642. Listed at 13 retailers as of October 25, 2026, with prices from $589 to $1,362, a $772 spread on the same certified stone. MOH London lists it at $1,362. 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.
