About this 3.05ct natural marquise diamond

This 3.05ct natural marquise sits in the three to five 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 2547515991. Listed at 5 retailers as of November 4, 2026, with prices from $33,564 to $61,042, a $27,478 spread on the same certified stone. MOH London lists it at $61,042. 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.
