About this 1.26ct natural heart diamond

This 1.26ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5453335159. Listed at 3 retailers as of November 5, 2026, with prices from HK$24,751 to HK$34,434, a HK$9,684 spread on the same certified stone. 77 Diamonds lists it at HK$34,434. 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.
