This 0.83ct natural marquise sits in the just-under-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 6187406158. Listed at 3 retailers as of November 1, 2026, with prices from $1,457 to $2,226, a $769 spread on the same certified stone. 77 Diamonds lists it at $2,226. 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.
