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 IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2537178421. Listed at 3 retailers as of November 1, 2026, with prices from $1,085 to $1,822, a $737 spread on the same certified stone. MOH London lists it at $1,822. 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.
