About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6243093257. Listed at 13 retailers as of October 31, 2026, with prices from HK$17,232 to HK$32,167, a HK$14,936 spread on the same certified stone. Helzberg Diamonds lists it at HK$32,167. 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.
