About this 0.91ct natural marquise diamond

This 0.91ct natural marquise sits in the just-under-one-carat band, graded I 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 1545694495. Listed at 5 retailers as of October 31, 2026, with prices from €1,361 to €1,641, a €280 spread on the same certified stone. Blue Nile lists it at €1,641. 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.
