About this 0.98ct lab-grown oval diamond

This 0.98ct lab-grown oval sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG510157938 or 510157938. Listed at a single retailer as of October 30, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
