About this 0.4ct natural princess diamond

This 0.4ct natural princess sits in the sub-half-carat band, graded J 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 2564275278. Listed at 4 retailers as of October 31, 2026, with prices from $335 to $433, a $99 spread on the same certified stone. 77 Diamonds lists it at $433. 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.
