About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded G 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 1549091183. Listed at 23 retailers as of November 1, 2026, with prices from HK$28,120 to HK$59,319, a HK$31,199 spread on the same certified stone. MOH London lists it at HK$59,319. 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.
