About this 1.03ct natural marquise diamond

This 1.03ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5543716987. Listed at 18 retailers as of November 5, 2026, with prices from £1,128 to £3,186, a £2,058 spread on the same certified stone. NZ Jewellers lists it at £3,186. 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.
