About this 0.31ct natural marquise diamond

This 0.31ct natural marquise sits in the sub-half-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7552847151. Listed at 3 retailers as of November 3, 2026, with prices from HK$1,597 to HK$2,288, a HK$692 spread on the same certified stone. 77 Diamonds lists it at HK$2,288. 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.
