About this 1.28ct natural oval diamond

This 1.28ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and I1 clarity (included) and certified by SHANE. 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.
