This 1.37ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG451080467 or 451080467. Listed at 3 retailers as of November 4, 2026, with prices from HK$4,354 to HK$9,934, a HK$5,580 spread on the same certified stone. MOH London lists it at HK$9,934. 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.
