This 3.12ct lab-grown oval sits in the three to five carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG779643285 or 779643285. Listed at 28 retailers as of October 29, 2026, with prices from $1,791 to $9,930, a $8,139 spread on the same certified stone. Brilliant Earth lists it at $9,930. 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.
