About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6561190742. Listed at 2 retailers as of November 6, 2026, with prices from $1,218 to $1,948, a $730 spread on the same certified stone. 77 Diamonds lists it at $1,948. 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.
