The atelier

The silver used in our designs is 92.5% pure, commonly known as sterling silver, with the remaining 7.5% made up of other metals. All our silver is recycled, giving new life to precious materials. To achieve a striking black finish, we use a special treatment that accelerates silver’s natural oxidation process. This creates sulfide compounds on the surface, forming a rich black patina. Over time, this layer naturally wears away, allowing the piece to evolve with you, creating a unique, personal finish.

Our recycled yellow gold alloys are created by adding silver and copper to pure gold. The higher content of pure gold in 18 ct (75%) alloy gives it a richer, warmer yellow tone, while 14 ct (58.5%) appears lighter and more subdued. Known for its timeless appeal, yellow gold remains the most classic and enduring choice.

Our recycled white gold is made by combining pure gold with palladium, creating a refined anthracite-grey hue. The visual difference between 14 ct and 18 ct is subtle, yet both stand out for their strength and resistance. Chosen for its modern & minimalistic character, white gold offers a contemporary edge.

Our recycled rose gold contains copper as the main alloying metal, giving it its characteristic pink hue. The color difference between 14 ct and 18 ct is minimal, with both offering a soft, warm tone that feels timeless and elegant.

Diamonds are among the most captivating gemstones, each one unique in its brilliance and character. We work exclusively with natural diamonds, with a deep appreciation for the 4C’s and a focus on the highest qualities available. The only exception is salt & pepper diamonds, whose inclusions are embraced as part of their distinctive character, in harmony with INNAN’s design aesthetic.

At INNAN, we are especially drawn to natural coloured diamonds, valuing their individuality and the harmonious way they interact with metal tones giving each piece its distinctive character. All diamonds are mindfully selected reflecting our commitment to responsible craftsmanship. When selecting a diamond, four main characteristics - known as the 4C’s - determine its quality and appearance:

Cut

The cut defines how well a diamond reflects light, influencing its sparkle and overall visual appeal. A well-cut diamond will appear lively and radiant.

Colour

Diamonds range from colourless to naturally tinted shades such as champagne, yellow or grey. At INNAN, we embrace these natural colours for their depth, warmth, and unique character.

Clarity

Clarity refers to the presence of internal or external features known as inclusions. These natural marks can be part of the stone’s identity and can enhance its individuality — especially in salt & pepper diamonds, whose distinctive patterns and character bring a unique personality that perfectly complements certain designs.

Carat

Carat represents the diamond’s weight and size. While larger stones can make a statement, smaller ones often offer refined balance and delicacy.

Sapphires are among the hardest gemstones used in jewellery, second only to diamonds in durability. This exceptional hardness makes them highly resistant to scratching and particularly well suited for everyday wear, including engagement rings and heirloom pieces. Best known for their deep blue tones, sapphires actually occur in a wide spectrum of colours - from soft pastels to vivid greens, yellows, pinks, and purples. Each stone carries its own character, shaped by subtle variations in colour and natural formation. Formed deep within the earth over millions of years, sapphires belong to the mineral family corundum, the same mineral group as ruby. Their strength and timeless beauty have made them one of the most cherished gemstones throughout history. At INNAN Jewellery Atelier, sapphires are carefully selected for their individuality, colour depth, and natural beauty. Rather than seeking perfect uniformity, we value stones with distinctive tones and character, allowing each jewel to feel truly one of a kind.

Spinels are admired for their vivid colour, natural brilliance, and remarkable character. They are durable gemstones that are well suited for jewellery designed to be worn and enjoyed regularly. Naturally occurring in a wide range of shades, spinels can appear in tones of grey (in Inna’s vocabulary, “dramatic grey”), lavender, violet, pink, red, blue, and deep green. Inna is particularly drawn to the cooler shades of spinel, which pair beautifully with white gold or silver to create a bold, minimalistic look.

For centuries, spinels were mistaken for other precious stones, particularly rubies and sapphires, due to their brightness and beauty. Today, they are appreciated in their own right for their clarity, luminosity, and unique palette. At INNAN Jewellery Atelier, spinels are chosen for their distinctive tones and expressive presence. Especially celebrated are stones with unusual shades - gemstones that bring character and a slightly unexpected edge to a piece.

Emeralds are cherished for their vibrant green colour. Their rich tones, ranging from deep forest green to softer bluish greens, have captivated jewellery lovers for centuries. Formed under rare geological conditions, emeralds often contain natural inclusions within the stone. Rather than diminishing their beauty, these internal features are considered part of the gemstone’s identity and are often referred to as the stone’s “garden.” Each emerald therefore carries a distinctive character that makes it truly one of a kind.

Due to their natural internal structure, emeralds are more delicate than many other gemstones and should be worn with a certain degree of care. Their beauty lies not only in their colour, but also in their organic nature and individuality.
