About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded L 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 6461035862. Listed at 4 retailers as of November 4, 2026, with prices from HK$13,872 to HK$21,458, a HK$7,585 spread on the same certified stone. 77 Diamonds lists it at HK$21,458. 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.
