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 1216663338. Listed at 5 retailers as of November 4, 2026, with prices from HK$27,470 to HK$40,600, a HK$13,130 spread on the same certified stone. 77 Diamonds lists it at HK$40,600. 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.
