Details

Images from different angles

Titanium/germanium effects are produced from every surface of the necklace




99.99% purified germanium solution is coated on the pure titanium surface by our special coating technology. This ensures that titanium/germanium effects are produced from every surface of the necklace, while many products on the market have only some titanium/germanium balls.

Rhodium-plated surface which shines like white gold!


The rhodium-plated surface of the necklace shines brilliantly like white gold. This luxurious jewelry not only produces positive effects on health but also will enhances your style at any occasion.

No need to take off when bathing or swimming in the sea. It will last long!


You do not need to take off the necklace when bathing or swimming in the sea. The surface, which is precisely finished by Japanese craftsmanship, ensures long-lasting shine and is less likely to tarnish in contrast to silver products.

Lightweight stylish curb chain which does not look like a health related product


The curb chain designed for both men and women does not look like a health related product and will compliment any outfit.

The necklace measures 5mm wide and 55cm,60cm/21.6inches,23.6inches long but it weighs only 15g,16g/0.52oz,0.56oz due to the small specific gravity of titanium, which is not heavy to wear.

Specially designed center folding clasp processed to enhance mechanical strength - Firmly connects the both ends


The specially designed center folding clasp allows you to put on and take off easily once you get used to it.

While many products use ready-made clasps, this necklace uses the specially designed pure titanium clasp processed to enhance mechanical strength in order to connect the both ends firmly. This is part of our dedication to details.

Shipped in a nice jewelry box!


This necklace is shipped in a nice jewelry box. We offer free gift wrapping service. Please select "Gift Wrapping: Yes" when you place an order.

* Boxes may vary slightly.

Length adjustment

We will adjust the length of your necklace/bracelet free of charge after purchase. However, please note it could cost less to get the length altered at your local jewelry shop than the cost of shipping the product to us for alteration.
