About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2564382881. Listed at 15 retailers as of October 31, 2026, with prices from €1,551 to €2,589, a €1,038 spread on the same certified stone. Wholesale Diamonds Direct lists it at €2,589. 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.
