This 3.05ct lab-grown oval sits in the three to five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG720598342 or 720598342. Listed at 16 retailers as of November 3, 2026, with prices from $610 to $4,031, a $3,422 spread on the same certified stone. Brilliant Earth lists it at $4,031. 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.
