# No.73 Niche Pattern Pure Tantalum Ring

Part of our rare-metal custom collection, the No.73 Ring is crafted from pure tantalum, the 73rd element on the periodic table.

Tantalum is known for its exceptional corrosion resistance, durability, and biocompatibility. Its naturally cool gray tone carries a subtle blue undertone, reminiscent of the night sky. The short, bold lines across the surface evoke meteors streaking through the darkness.

Tantalum and niobium are often found together in nature, yet each possesses its own distinct character and purpose. They do not need to be identical or inseparable to belong together. For this reason, the No.73 Tantalum Ring and No.41 Niobium Ring make a naturally complementary pair.
