About this 0.53ct natural marquise diamond

This 0.53ct natural marquise sits in the half to three-quarter carat band, graded G 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 2557919458. Listed at 4 retailers as of November 6, 2026, with prices from HK$5,337 to HK$6,892, a HK$1,555 spread on the same certified stone. 77 Diamonds lists it at HK$6,892. 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.
