About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7566040319. Listed at 11 retailers as of November 1, 2026, with prices from HK$23,316 to HK$43,129, a HK$19,813 spread on the same certified stone. Wholesale Diamonds Direct lists it at HK$43,129. 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.
