Titanium is a low density, strong, lustrous, corrosion-resistant (including sea water, aqua regia and chlorine) metal with a silver color.
It was discovered in Great Britain by William Gregor in 1791, and named by Martin Heinrich Klaproth for the Titans of Greek mythology
William Henry uses only aerospace-grade titanium alloy for our frames, clips, and micro-fasteners. Called 6Al/4V, it is titanium with a little aluminum and vanadium added in for additional toughness and tensile strength.
Topaz is a rare, extremely hard gemstone with an exceptionally wide color range that, besides brown, includes various tones and saturations of blue, green, yellow, orange, red, pink, and purple.
The ancient Greeks believed that topaz gave them strength. In Europe during the Renaissance (the period from the 1300s to the 1600s) people thought that topaz could break magic spells and dispel anger. For centuries, many people in India have believed that topaz worn above the heart assures long life, beauty, and intelligence.
Today, topaz is one of the US birthstones for November, while blue topaz is a birthstone for December
Apple coral is part of the species of corals known as melithaea sponge, which is commonly found on the ocean floors around the waters of Taiwan, Indonesia and southern China. The destruction of coral reefs around the world led to a global ban on coral mining and collecting in 1992, but apple coral was not included.
The United States has placed a ban on shipping coral in and out of the country, but there is no ban on the melithaea sponge corals.
Our apple coral is infused with zinc to obtain a beautiful and original pattern.
