About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557752766. Listed at 13 retailers as of October 31, 2026, with prices from HK$27,600 to HK$49,462, a HK$21,862 spread on the same certified stone. Helzberg Diamonds lists it at HK$49,462. 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.
