This 1.5ct lab-grown oval sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG683595170 or 683595170. Listed at 16 retailers as of October 29, 2026, with prices from $243 to $1,226, a $983 spread on the same certified stone. Brilliance lists it at $1,226. 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.
