About this 0.53ct natural cushion diamond

This 0.53ct natural cushion sits in the half to three-quarter 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 5182028514. Listed at 3 retailers as of November 1, 2026, with prices from HK$6,065 to HK$9,655, a HK$3,590 spread on the same certified stone. 77 Diamonds lists it at HK$9,655. 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.
