About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5232987303. Listed at 12 retailers as of October 27, 2026, with prices from £1,161 to £2,228, a £1,068 spread on the same certified stone. Wholesale Diamonds Direct lists it at £2,228. 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.
