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 SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2554510619. Listed at 8 retailers as of November 6, 2026, with prices from HK$18,136 to HK$24,935, a HK$6,799 spread on the same certified stone. Yorxs lists it at HK$24,935. 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.
