About this 0.69ct natural marquise diamond

This 0.69ct natural marquise sits in the half to three-quarter 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 5221677381. Listed at 2 retailers as of November 4, 2026, with prices from £488 to £569, a £81 spread on the same certified stone. B2C Jewels lists it at £569. 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.
