About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231335239. Listed at 7 retailers as of October 31, 2026, with prices from HK$18,987 to HK$26,518, a HK$7,531 spread on the same certified stone. Yorxs lists it at HK$26,518. 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.
