About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded I 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 5172058360. Listed at 23 retailers as of November 4, 2026, with prices from HK$30,636 to HK$64,001, a HK$33,365 spread on the same certified stone. MOH London lists it at HK$64,001. 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.
