About this 0.9ct natural marquise diamond

This 0.9ct 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 6481414208. Listed at 9 retailers as of November 1, 2026, with prices from £1,121 to £1,645, a £525 spread on the same certified stone. GemTrove lists it at £1,645. 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.
