This 0.42ct lab-grown round sits in the sub-half-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LGF6G39218 or F6G39218. Listed at 2 retailers as of October 31, 2026, with prices from ₹44,981 to ₹75,770, a ₹30,789 spread on the same certified stone. 18carati lists it at ₹75,770. 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.
