About this 0.91ct natural marquise diamond

This 0.91ct natural marquise sits in the just-under-one-carat band, graded H 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 2564688575. Listed at 10 retailers as of October 27, 2026, with prices from $2,098 to $4,011, a $1,913 spread on the same certified stone. Wholesale Diamonds Direct lists it at $4,011. 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.
