Gemstones are rare minerals that are often incorporated into jewelry and decorative objects. They are characterized by beauty, including visual aspects such as color, shine, fire, transparency and light effects. Durability is also an important characteristic, with attention paid to hardness, fragility/cleavage and chemical resistance. Rarity plays a role in how often a gemstone is found in nature. There are many cuts for gemstones, with the basic distinction being cabochon, a spherical cut, and faceted, where the surface of the gemstone is cut into multiple facets. During the cutting process, properties such as color, color distribution, inclusions, special light effects, dispersion, and fracture and cut surfaces are taken into account. Gemstones are incorporated into necklaces, earrings, bracelets, and other jewelry, and also find industrial applications. Some well-known gemstones include diamond, ruby, emerald, sapphire, aquamarine, topaz, tourmaline, amethyst, citrine, carnelian, opal, onyx, turquoise, lapis lazuli, and garnet. In the 18th and early 19th centuries, it was fashionable to make jewelry with a person's name or initials incorporated into it. The choice of gemstones was guided by the first letter of the gemstone name, which led to the gem alphabet. In the 19th century, acrostic jewellery was also made, in which sentiments were expressed in precious stones. The best known of these is the English 'regard' ring, an engagement ring in which the word 'regard' was formed by the precious stones ruby, emerald, garnet, amethyst and diamond.
