About this 1.29ct natural marquise diamond

This 1.29ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1549671213. Listed at a single retailer as of November 6, 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.
