About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LGS2F15856 or S2F15856. Listed at 2 retailers as of October 30, 2026, with prices from HK$7,993 to HK$13,766, a HK$5,772 spread on the same certified stone. Yorxs lists it at HK$13,766. 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.
