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.
Koa is a fabled tree, and wood, sourced responsibly from the Hawaiian islands. It is reddish brown in color, takes a beautiful polish, and can occasionally offer very fine figuring/curl and chattoyance. William Henry uses only the highest grade of figured Koa (as available) for our work, resin-stabilized for durability.
Citrine is a variety of quartz whose color ranges from a pale yellow to brown due to ferric impurities.
The name is derived from Latin citrina which means "yellow" and is also the origin of the word "citron." Sometimes citrine and amethyst can be found together in the same crystal, which is then referred to as ametrine.
