About this 0.4ct natural oval diamond

This 0.4ct natural oval sits in the sub-half-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2557857621. Listed at 7 retailers as of October 30, 2026, with prices from $733 to $2,093, a $1,360 spread on the same certified stone. Diamond Exchange Canada lists it at $2,093. 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.
