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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566155218. Listed at 13 retailers as of October 27, 2026, with prices from $1,605 to $2,991, a $1,386 spread on the same certified stone. Wholesale Diamonds Direct lists it at $2,991. 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.
