Craft and form

This ring from the Sirius collection is completely handcrafted in 14 karat yellow gold. At the centre is a 6-mm round-cut tourmaline in a greenish-yellow hue. The ring has a width of 5 mm, a thickness of 1.2 mm and a ring size 18.

The combination of a subtly worked texture and a polished finish creates a beautiful play of light, showing off the colour of the tourmaline. The granules along the setting add detail to the design and are a recognisable part of my work.

Colour and character of the tourmaline

This tourmaline has a fresh, bright appearance due to its green-and-yellow hue. Colours often associated with renewal and energy. Because of its round cut, the gemstone captures light from all sides, creating a vibrant sparkle without being unsettling.

The meaning of Sirius

The name Sirius came about after a visit to the observatory in Lochem, the Netherlands. Sirius is the brightest star in the sky and, in ancient cultures, was a symbol of brightness and direction. That idea is the basis of this collection: one gemstone that carries the design.

The Sirius collection consists of powerful, recognisable rings that balance form, material and gemstone.

Timeless and personal

Each ring is handmade in my atelier in Beltrum. The combination of gold, gemstones, and granules creates a signature reflected in each piece. A ring that stands out for its simplicity and detail, and is easy to wear.

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.

Craft and form

This ring from the Sirius collection is handcrafted in 14-karat yellow gold and built around a 9-mm cabochon-cut green tourmaline. On either side shine two diamonds, each measuring 2.95 mm (0.10 ct each, colour F/G, quality VSI). The soft sparkle of tourmaline and the refined brilliance of diamond subtly enhance each other. This creates a classic ensemble with a contemporary Kobak signature.

The depth and character of the stone

The green tourmaline is a cabochon cut, revealing its inner world beautifully. If you look closely, you can see slight inclusions – natural structures created during the stone’s growth process. They do not form imperfections, but unique patterns that give the stone its own identity.

In this tourmaline, the inclusions almost seem to move in the light. They create a depth reminiscent of a small galaxy in green. As a result, the stone seems alive; each turn of the hand reveals a different facet of what nature has shaped over millions of years.

This ring from the Sirius collection is crafted in 14-karat yellow gold and set with an oval-cut bi-colored tourmaline measuring 8 x 6 mm. The stone shows a gentle color gradient from pale pink to a warm, almost peachy hue. The ring band has a subtle texture and, like the granules and the setting, is highly polished. This creates a play of light that further enhances the color gradient of the tourmaline.

The color and meaning of the tourmaline

Tourmaline is vibrant and refined at the same time. The natural transition of hues makes the stone appear to move with the light. That play of colors creates a soft, feminine look without the ring losing its power. Pink is often seen as the color of softness and connection. In this bi-colored tourmaline, that comes to life – a harmony of hues that subtly blend together.

Tourmaline is one of the most versatile gemstones around. She is known for her rich color spectrum and natural energy. The bi-colored varieties are particularly sought after precisely because they combine two worlds. As a result, each stone has a unique character. No two rings are ever alike.

The meaning of Sirius

The name Sirius came about after a visit with my family to the observatory in Lochem. There an astronomer told us about Sirius, the brightest star in our sky and part of the constellation Canis Major – the Great Dog. In ancient cultures, this star symbolised brightness, direction and return.
As I listened, I thought of the rings I had been making for some time: one stone, one source of light. That’s how I knew they had to bear the name Sirius.

Timeless elegance

The Sirius collection represents clean lines, powerful shapes and gemstones with meaning. Each piece of jewellery is made entirely by hand in the Beltrum atelier.. The granules along the ring add extra detail and balance to the design. In addition, they provide a recognizable Kobak accent where craft and timeless design come together.

This ring is a timeless choice for those who love color, craftsmanship and a piece of jewelry with character. She is designed to be worn as well as passed on.

This ring from the Sirius collection is crafted in 14-karat yellow gold and set with an oval-cut green tourmaline measuring 8.2 x 6 mm. The ring band has a subtle texture and, like the granules and the setting, is highly polished. Because of that finish, the gold captures light in a sophisticated way. The structure plays with reflection, adding depth and dimension.

The color and depth of the stone

The tourmaline is highly polished, giving it remarkable volume and vibrancy. Its depth makes the color exceptionally intense – a green that seems to breathe. Depending on the light, the stone shows shades from fresh emerald green to deeper moss green. As a result, the high grind creates a special glow: the light seems to gather in the stone and release in layers. This creates a natural depth that gives this tourmaline its distinctive character.

Tourmaline is one of the most versatile gemstones around. Green tourmaline is often associated with balance and strength. Not as a promise, but as a reference to its vibrant character and origin. Moreover, each stone is unique; no two show exactly the same play of color and light.

The meaning of Sirius

The name Sirius took on meaning after a visit with my family to the observatory in Lochem. There, an astronomer told us about the star Sirius – the brightest in our sky and part of the constellation Canis Major (the Great Dog). In ancient cultures, this star symbolized brightness, direction and return. That was when her rise coincided with the flooding of the Nile and the beginning of a new season.

As I listened, I thought of the rings I had been making for some time: one stone, one source of light. That’s why I knew this collection had to be called Sirius.

Contrasts.

What this series of rings is also about is the use of the color of the gemstones, with the way the ring is worked. I love adding texture/texture to the ring’s band, as it has an awful lot of effect on how a ring will look in the end. Pictured is the ring with a trilliant-cut red tourmaline set in a 14K yellow gold ring. The ring features a hammered effect with triangles and is then polished. All parts are handmade in the workshop in Beltrum, and all the details together, make it a striking one-of-a-kind design and piece of jewellery. Materials:

• 14K yellow gold
• Red tourmaline

Gemstone size:

• 6x6x6mm – 0.60ct

Ring dimensions:

• Width of the ring is 5mm
• The thickness of the ring is 1.2mm
• Ring size is 19 (Note: this Sirius ring, due to the motif, can only be made smaller)

This ring from the Sirius collection is crafted in 14-karat yellow gold and set with an oval-cut lavender-colored tourmaline measuring 9 x 7 mm (1.69 ct). The ring band has an angular hammered texture and is fully polished. As a result, the gold captures light in different ways. The subtle texture plays with reflection and adds depth and dimension to the whole.

The special color of lavender tourmaline

The tourmaline is exceptional in color. Lavender-colored tourmalines are rare within the tourmaline spectrum. Their soft violet tones arise from traces of manganese and iron. Depending on the light, the tourmaline changes from cool lilac to a warm, pink glow. This creates a color that exudes both tranquility and strength – subdued, but vibrant.

The inspiration behind the name Sirius

The name Sirius took on meaning after a visit with my family to the observatory in Lochem. There, an astronomer told us about the star Sirius, the brightest in our sky and part of the constellation Canis Major – the Great Dog. In ancient cultures, this star symbolized brightness, direction and return. It was the moment when her emergence coincided with the flooding of the Nile and the beginning of a new season.
As I listened, I thought about the rings I had been making for some time: one stone, one source of light. That’s how I knew they had to be named Sirius.

Craft and detail

Six small diamonds (VVS/F) are subtly incorporated into the design. They enhance the brightness of the tourmaline without being overpowering. The handmade granules and polished finish add extra detail to the design. This is characteristic of the Sirius collection: clean lines, powerful shapes and gemstones with meaning.

Timeless and made with care

This ring is a timeless choice for those who love color, craftsmanship and a piece of jewelry with character. She is made to last for generations and be worn with pride.

Contrasts and Structures

This series of rings is also all about the colors of the gemstones and how they combine with the processing of the ring. I love adding structure and texture to a ring’s band because it dramatically affects its final look. Pictured is a ring with a round-cut indigolite blue tourmaline set in a 14kt yellow gold ring. The ring is deliberately left smooth and only matted so that the intensely beautiful indigolite blue tourmaline is shown to its best advantage. This shade of blue is rare among tourmalines.

Handmade in Beltrum

All parts of this ring are handmade in my workshop in Beltrum. The attention to detail makes this piece of jewelry a striking one-of-a-kind design. Materials: – 14kt yellow gold – Indigolite tourmaline Dimensions of gemstone: – 7mm – 1.42ct Dimensions of ring: – Width: 6mm – Thickness: 1.2mm – Ring size: 18.25

This ring from the Sirius collection is crafted in 14-karat yellow gold and set with an oval-cut cognac-colored tourmaline measuring 8 x 6 mm (1.20 ct). The ring band has a pronounced hammer finish with horizontal strokes and is then polished. This combination of texture and shine creates a subtle contrast that beautifully distributes light across the surface. This gives the ring a lively and warm character.

The colour and depth of the stone

Tourmaline has a deep, warm cognate tone with nuances of copper, honey, and reddish-brown. That colour results from traces of iron and manganese in the crystal structure of the stone. Depending on the light, tourmaline exhibits different shades, ranging from soft golden brown to deeper orange-brown. Thus, a distinct glow emerges each time.

Cognac-coloured tourmalines are loved for their natural warmth. They combine effortlessly with yellow gold, giving a piece of jewellery a classic yet contemporary look. Moreover, this colour exudes tranquillity and stability – qualities that complement the character of the Sirius collection nicely.

This ring from the Sirius collection is crafted in 14-karat yellow gold and set with a 7 mm (1.39 ct) round-cut deep pink tourmaline. The ring band has a pronounced hammered texture with soft curves and is then matted. This combination of relief and matte finish creates a subtle play of light and shadow. This gives the ring character without losing its sophistication.

The color and appearance of the stone

The tourmaline has an intense, vibrant pink hue that immediately catches the eye. Her color is powerful but not bright; she has depth and warmth at the same time. With its round cut, the stone captures light from every angle, creating a brilliance that keeps changing with the movement of the hand.
Deep pink tourmaline is rare and loved for its pure color tone and energy. In gemology, pink is often seen as a symbol of love, softness and zest for life. As a result, this stone not only has a strong aura, but also an emotional charge – it feels personal and alive.
