Sirius – Penumbra
€3,575.00
Craft and form
This ring from the Sirius collection is handcrafted in 14-karat yellow gold. The design revolves around a faceted Tahiti pearl measuring 9.7 mm. Due to the special cut, the light refracts itself into small areas, revealing new hues with every movement: deep gray, anthracite and a subtle green glow. Six diamonds in warm shades of brown (1.7 mm, 0.02 ct each) surround the pearl. They add a soft sparkle without distracting attention from the focal point. The matte finish and granules on the ring binder bring balance and tranquility to the whole.
The depth and character of the pearl
A faceted pearl does not compare to a classic, smooth pearl. Light moves through the facets, revealing different colors each time. This Tahiti pearl seems to be alive; its surface constantly shows a new glow, as if depth lurks behind the pearl. That effect immediately gave me a sense of the universe: light showing itself in shadow and movement emerging in stillness. I wanted to capture exactly that interplay of light and darkness in this design.
The meaning of Sirius
The name Sirius refers to the brightest star in our sky, part of the constellation Canis Major, also known as the Great Dog. In ancient cultures, this star symbolised brightness, direction and return. While visiting the observatory in Lochem, I heard this story, and it touched me. One star, one source of light – exactly what I was looking for in my rings. That is why this collection was named Sirius.
Timeless elegance
The ring has a warm, calm look and a natural balance of shine and texture. The granules on the ring band highlight the craft used to make each piece – characteristic of the Sirius collection. Each piece of jewellery is made entirely by hand in the Beltrum workshop, with attention to durability and a quality that will last for generations. The name Penumbra refers to the half-light between dark and bright: the area where light does not show itself immediately, but becomes visible again and again.
