About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded H 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 1569645931. Listed at 13 retailers as of November 4, 2026, with prices from HK$25,268 to HK$47,871, a HK$22,603 spread on the same certified stone. Helzberg Diamonds lists it at HK$47,871. 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.
