About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2536383775. Listed at 5 retailers as of November 2, 2026, with prices from HK$2,291 to HK$3,410, a HK$1,119 spread on the same certified stone. 77 Diamonds lists it at HK$3,410. 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.
