About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1557256870. Listed at 12 retailers as of November 5, 2026, with prices from HK$15,612 to HK$31,171, a HK$15,559 spread on the same certified stone. Wholesale Diamonds Direct lists it at HK$31,171. 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.
