Remember, with proper care and knowledge of your jewelry, your piece can last a lifetime.
Shower. It’s not a great idea to shower with your jewelry on, but once in a while isn’t going to do any lasting damage. Just make sure to dry it after.
Swimming Pool. Take your silver off. Chlorine is a pretty harsh chemical, so if you accidentally forget to remove your silver jewelry before hopping in, make sure to rinse and clean it afterward. Hot tub is the same thing but heat heat can accelerate the chemical reaction.
Hot Springs. The sulfur in natural hot springs will wreak havoc on your silver. Unless you’re going for that “dark oxidized” look, avoid at all costs.
Bonus Tip: Chemicals in lotions and perfumes can also cause your jewelry to tarnish. Apply them first, let them dry, and then put your jewelry on.
Prehnite is an inosilicate of calcium and aluminium. Prehnite is brittle with an uneven fracture and a vitreous to pearly luster. Its hardness is 6-6.5, its specific gravity is 2.80-2.90 and its color varies from light green to yellow, but also colorless, blue, pink or white.
Emerald is a gemstone and a variety of the mineral beryl colored green by trace amounts of chromium and/or sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness is classified as generally poor. Emerald is a cyclosilicate.
Peridot, sometimes called chrysolite, is gem-quality olivine and a silicate mineral. As peridot is a magnesium-rich variety of olivine, the formula approaches Mg₂SiO₄. Its green color is dependent on the iron contents within the structure of the gem.
