About this 1.19ct natural cushion diamond

This 1.19ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1283378374. Listed at 15 retailers as of November 4, 2026, with prices from HK$18,888 to HK$39,874, a HK$20,986 spread on the same certified stone. MOH London lists it at HK$39,874. 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.
