About this 0.4ct natural oval diamond

This 0.4ct natural oval sits in the sub-half-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3535201937. Listed at 21 retailers as of November 1, 2026, with prices from $556 to $1,780, a $1,225 spread on the same certified stone. MOH London lists it at $1,780. 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.
