Tantalum - named after Tantalus, the son of Zeus - is a mysteriously shimmering, dark metal.
It defies even the strongest acids and only melts at over 3,000 °C.
It is harder than platinum, colourfast, has a noble weight and there are no known allergies or intolerances.
It is the rarest stable isotope among the elements in our solar system, making it a wonderful symbol for lovers looking for special and handcrafted rings for their unique relationship.
