This 1.25ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG569329078 or 569329078. Listed at 11 retailers as of November 1, 2026, with prices from HK$3,174 to HK$15,398, a HK$12,224 spread on the same certified stone. MOH London lists it at HK$15,398. 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.
