About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2536739391. Listed at 10 retailers as of November 5, 2026, with prices from $4,533 to $7,611, a $3,078 spread on the same certified stone. Wholesale Diamonds Direct lists it at $7,611. 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.
