This 1.85ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG516238514 or 516238514. Listed at 12 retailers as of October 28, 2026, with prices from HK$3,311 to HK$10,474, a HK$7,163 spread on the same certified stone. Rare Carat lists it at HK$10,474. 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.
