This 1.75ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG533209429 or 533209429. Listed at 13 retailers as of October 29, 2026, with prices from $1,007 to $2,577, a $1,570 spread on the same certified stone. MOH London lists it at $2,577. 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.
