About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5546366314. Listed at 7 retailers as of November 5, 2026, with prices from HK$41,460 to HK$54,135, a HK$12,675 spread on the same certified stone. Cape Diamonds lists it at HK$54,135. 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.
