About this 0.8ct natural marquise diamond

This 0.8ct natural marquise sits in the just-under-one-carat band, graded I 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 1563217511. Listed at 13 retailers as of October 31, 2026, with prices from $1,386 to $2,484, a $1,099 spread on the same certified stone. Helzberg Diamonds lists it at $2,484. 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.
