About this 0.55ct natural marquise diamond

This 0.55ct natural marquise sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2568688399. Listed at 2 retailers as of November 1, 2026, with prices from £458 to £555, a £96 spread on the same certified stone. 77 Diamonds lists it at £555. 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.
