Why teal sapphires are the engagement stone of the moment

Teal sapphires sit in the space between ocean blue and forest green, and no two are alike. Many of the stones we set come from Australian mines, where the same crystal can show two or three colours depending on the light — that is what gemmologists call parti sapphire.

Built for everyday wear

At 9 on the Mohs scale, sapphire is second only to diamond in hardness. It shrugs off the knocks of daily life, which is why we recommend it for engagement rings worn every day for decades.

How we choose them

We look for saturation without darkness, even colour across the table and a cut that keeps the stone lively. Every NUR sapphire is accompanied by a gemmological report.
