About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2241069416. Listed at 15 retailers as of October 31, 2026, with prices from HK$14,904 to HK$27,532, a HK$12,628 spread on the same certified stone. Helzberg Diamonds lists it at HK$27,532. 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.
