About this 0.8ct natural marquise diamond

This 0.8ct natural marquise sits in the just-under-one-carat band, graded G 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 6561525671. Listed at 4 retailers as of October 31, 2026, with prices from $1,541 to $1,829, a $288 spread on the same certified stone. Blue Nile lists it at $1,829. 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.
