This 1.25ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG837626183 or 837626183. Listed at 17 retailers as of November 3, 2026, with prices from $554 to $3,270, a $2,716 spread on the same certified stone. Brilliant Earth lists it at $3,270. 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.
