Product description
⚫ Tensor amulet with onyx – gold-plated 925 sterling silver
A Royal Cubit made of 925 sterling silver, gold-plated with 18K gold. The frame holds a composition of hand-cut minerals with onyx, set in epoxy resin and visible from both sides.
Under the gold plating there is solid 925 sterling silver. The plating itself is a layer, so with daily wear it can rub through at the edges over time and then the silver underneath shows. The silver stays.

🌍 Onyx
- Country of origin: India
- Mineral group: quartz (chalcedony)
- Hardness: 6.5–7 on the Mohs scale
Onyx is a banded chalcedony, and in the black version the bands are uniform. The Romans cut it into cameos, using the difference in colour between the layers: a white relief on a black ground is precisely onyx. The stone takes a very deep polish, which makes it look more massive than it weighs.

✨ The Royal Cubit and the ROYAL TERRA collection
The Royal Cubit is a tensor geometry tuned to 144 MHz. The ring closes into a form which, in the tensor tradition, is said to create its own field and hold the owner's intention. The bail does not touch the ring, so as not to close it.
The sign of the ROYAL TERRA collection is the octagon, the figure eight, a shape of balance and flow. Gold-plated silver gives the same gold tone as 585 gold, at a price closer to brass.
