About this 0.4ct natural marquise diamond

This 0.4ct natural marquise sits in the sub-half-carat band, graded J 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 7542975651. Listed at 3 retailers as of November 2, 2026, with prices from $402 to $501, a $99 spread on the same certified stone. 77 Diamonds lists it at $501. 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.
