Semper Invicta Blue Topaz Ring Rose Gold

Ring Sizing

Choosing the correct ring size is essential for comfort, balance and security. All Semper rings are individually crafted to order using our official UK sizing standard. International size systems may vary and are provided as a guide only. Each order is produced to the Semper house standard.

If your measurement falls between sizes, we recommend selecting the larger size. For assistance before ordering, our team is always available. We recommend measuring carefully before confirming your size.

How to Measure

Option I: Measure an existing ring

Select a ring that fits the intended finger comfortably. Measure the internal diameter and compare it to the size chart.

Option II: Measure your finger

Wrap a thin strip of paper around the base of your finger. Mark where it overlaps and measure the length in millimetres. This is your finger circumference.

For best accuracy, measure at room temperature. Avoid sizing when hands are cold or swollen.

Bracelet Sizing

Finding the correct bracelet size ensures comfort, balance, and the intended presence on the wrist. Semper bracelets are designed to sit with a refined, natural drape, allowing the form and detailing to be fully appreciated.

Sizes refer to the internal length of the bracelet.

Fit Options:

Close fit (add 0.5 – 0.9 cm)
Sits nearer to the wrist with minimal movement.

Standard fit (add 1 – 1.5 cm)
Allows light movement while maintaining a refined, balanced presence.

Relaxed fit (add 1.6 – 2 cm)
Worn looser on the wrist, allowing greater drape and freedom of movement.

Because all Semper bracelets are made to order, we can accommodate precise or non-standard sizing. If you are between sizes, outside the listed measurements or would like a bracelet with a more precise fit crafted exactly to your wrist circumference, our ateliers can produce your piece to your exact specification.

For guidance, our client services team is always available to assist before ordering.
