About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded H 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 3415140293. Listed at 21 retailers as of October 31, 2026, with prices from HK$23,133 to HK$50,351, a HK$27,217 spread on the same certified stone. MOH London lists it at HK$50,351. 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.
