This 1.28ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG645412281 or 645412281. Listed at 16 retailers as of November 4, 2026, with prices from ₹25,553 to ₹1,25,450, a ₹99,897 spread on the same certified stone. Reve Diamonds lists it at ₹1,25,450.
