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 6551674574. Listed at 21 retailers as of October 29, 2026, with prices from $372 to $1,203, a $831 spread on the same certified stone. MOH London lists it at $1,203. 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.
