A central oval diamond, flanked by three stones on each side. The Joanne ring radiates balance and symmetry. A design full of romance and harmony. For those who choose with both heart and an eye for detail.

This ring, inspired by J.K. Rowling, pays tribute to the world-famous author with a creative spirit.

Joanne has achieved immortality through the creation of the enchanting "Harry Potter" book series, which has fascinated millions of readers worldwide. The lasting impression of her stories and characters extends to the ring, where the oval-cut dark green tourmaline represents the magic and richness of her creations. The subtly placed diamonds add a touch of elegance, making the ring a reflection of the creativity and enchanting world that J.K. Rowling created.

Tips & tricks

#1

If you're unsure between two sizes, choose the larger size.

#2

Measure your ring size at the end of the day, as your fingers are largest then.

#3

The wider the band, the tighter the fit. Choosing a wide ring? Go half a size up.

#4

Don’t measure your ring size when your hands are very cold. This could result in you measuring a ring size that’s too small.

#5

Alcohol and salt can cause your fingers to swell. If this happens, try measuring your ring size at another time.
