This 1.25ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG846641812 or 846641812. Listed at 17 retailers as of November 4, 2026, with prices from HK$1,906 to HK$9,084, a HK$7,178 spread on the same certified stone. Reve Diamonds lists it at HK$9,084. 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.
