About this 0.91ct natural marquise diamond

This 0.91ct natural marquise sits in the just-under-one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566411480. Listed at 5 retailers as of October 31, 2026, with prices from €1,779 to €2,133, a €354 spread on the same certified stone. Blue Nile lists it at €2,133. 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.
