This 1.02ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG550237333 or 550237333. Listed at 14 retailers as of October 25, 2026, with prices from $172 to $1,048, a $876 spread on the same certified stone. Reve Diamonds lists it at $1,048. 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.
