Guarantee

British Handcrafted Titanium Jewellery

Every Ti2 pieces are handmade in the UK, reflecting our dedication to precision, creativity, and ethical production. Every piece reflects a deep understanding of the material, its behaviour, and how it performs in everyday wear.

Two-Yar Titanium Warranty.

Titanium jewellery is designed for long-term wear, combining durable materials with careful craftsmanship. Each piece is made to perform as beautifully over time as it does on the first wear.

Ti2 Titanium jewellery is covered against manufacturing faults. Every Ti2 design is supported by a Two-Year manufacturing warranty, covering any making related issues, offering reassurance in its quality and construction.

AnchorCert Pro Accredited Jewellery
All Ti2 Titanium jewellery is independently tested under AnchorCert Pro, a recognised jewellery testing standard developed by the Birmingham Assay Office. This testing focuses on metal safety and skin comfort, making Ti2 particularly suitable for those with sensitive skin or metal allergies.

100% hypoallergenic Guarantee

Ti2 Titanium jewellery is crafted exclusively from commercially pure titanium (99.2%), most commonly Grade 2 - chosen for its balance of strength, lightness, and comfort. This pure titanium is 100% hypoallergenic by nature, making it ideal for sensitive skin.

Non-Painted, Metal-Formed ColourationTi2’s distinctive colours are created through anodising - an electrochemical process that alters the surface of the titanium itself. This means colour is not painted or coated on, but becomes part of the metal.

FAQ’s

Does titanium jewellery scratch easily?
No. Titanium is one of the strongest and most durable metals used in jewellery. Like all metals, it can show light marks with wear, but it is generally more resistant than most precious metals. Any fine surface marks are typically subtle and become part of the metal’s natural character over time.
Is this jewellery suitable for everyday wear?
Yes. Titanium pieces are designed for regular wear, combining exceptional strength with lightweight comfort.
Will the colour wear off over time?
Ti2 colours are formed through the metal itself, not paint or coating. With normal wear, colour is designed to remain vibrant but is liable to become damaged caused by abrasion.
Why does titanium feel different to silver or gold?
Titanium is lighter and warmer to wear, which many people find more comfortable, especially for earrings and rings. Titanium earrings are also a popular choice for sensitive skin and upper-ear piercings.
Is this jewellery designed to last?
Yes. From material choice to craftsmanship, Ti2 jewellery is made with longevity in mind and supported by a two-year warranty.
Will this feel heavy or bulky to wear?
No. Titanium is exceptionally lightweight, so pieces feel comfortable and easy to wear all day.
Is this a good choice if I react to most metals?Yes. Ti2 uses commercially pure titanium, which is naturally hypoallergenic and tested under AnchorCert Pro for skin comfort.
