About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-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 6551079120. Listed at 22 retailers as of October 28, 2026, with prices from HK$21,591 to HK$50,817, a HK$29,225 spread on the same certified stone. Queensmith lists it at HK$50,817. 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.
