About this 1.01ct natural marquise diamond

This 1.01ct natural marquise sits in the classic one-carat band, graded H 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 5242098943. Listed at 15 retailers as of October 31, 2026, with prices from HK$19,178 to HK$35,802, a HK$16,624 spread on the same certified stone. Helzberg Diamonds lists it at HK$35,802. 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.
