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.
Lapis lazuli or lapis for short, is a deep-blue metamorphic rock used as a semi-precious stone that has been prized since antiquity for its intense color. As early as the 7th millennium BCE, lapis lazuli was mined in the Sar-i Sang mines, in Shortugai, and in other mines in Badakhshan province in northeast Afghanistan. Lapis lazuli artifacts, dated to 7570 BCE, have been found at Bhirrana, which is the oldest site of Indus Valley Civilisation. Lapis was highly valued by the Indus Valley Civilisation (7570–1900 BCE).Lapis beads have been found at Neolithic burials in Mehrgarh, the Caucasus, and as far away as Mauritania. It was used in the funeral mask of Tutankhamun (1341–1323 BCE).
By the end of the Middle Ages, lapis lazuli began to be exported to Europe, where it was ground into powder and made into ultramarine, the finest and most expensive of all blue pigments. Ultramarine was used by some of the most important artists of the Renaissance and Baroque, including Masaccio, Perugino, Titian and Vermeer, and was often reserved for the clothing of the central figures of their paintings, especially the Virgin Mary. Ultramarine has also been found in dental tartar of medieval nuns and scribes.
Carnelian is a brownish-red mineral commonly used as a semi-precious gemstone. Similar to carnelian is sard, which is generally harder and darker. Both carnelian and sard are varieties of the silica mineral chalcedony colored by impurities of iron oxide.
