Safety Catch: One of several means of securing a brooch to a garment. Before the invention of safety catches, the most common means of securing a brooch was a simple “C” catch with no locking mechanism. A safety catch is simply a way to secure the pin to the “C” catch so that it doesn’t come undone and does not need to extend beyond the edge of the brooch.

Salt: A colorless or white crystalline solid, composed of Sodium chloride. It is found native in the earth, and is also produced by the evaporation and crystallization of sea water and other water impregnated with saline particles. Salt is used extensively in ground or granulated form as a food seasoning and preservative.

San Marco chain: A unique kind of chain wherein each link is long and rounded, resembling a puffed grain of rice with a flat bottom. The links are arranged next to each other at a 45 degree angle and attached to each other on the bottom by sturdy flat pins set at an opposite angle.

Sand Casting: For hundreds of years sand casting was the most popular of all casting methods. It still plays an important role in the production of large metal forms, (typically Iron, but also Bronze, Brass, Aluminum). Tempered sand is packed onto wood or metal pattern halves, removed from the pattern, and metal is poured into resultant cavities. Molds are broken to remove castings.

Sandstone: Just as the name implies, sandstone is a Sedimentary stone made of sand that has been fused with some cementing element like clay or quartz.

Sapphire: One of the four precious gemstones. The other three are diamonds, rubies, and emeralds. Sapphire is a member of the corundum family which come in a variety of colors from white to orange to green to pink. If a corundum gemstone is red, it is a ruby, but any other color are properly referred to as sapphires. Sapphires have been synthesized since the 1920’s. Ancient Persians believed the blueness of the sky was caused by the reflection from an enormous blue sapphire that the Earth rested on. Blue sapphire is the birthstone for September.

Sard: A deep orange-red to brownish-red variety of chalcedony.

Sardonyx: A variety of onyx consisting of alternating layers of Sard and white chalcedony.

Satin finish: A series of tiny parallel lines scratched onto a surface with a wire brush or polishing tool to produce texture

Scatter Pin: A small pin, usually featuring flowers, birds and insects, that is intended to be worn in a group with many other scatter pins.

Scepter: A symbol of spiritual and worldly power used as a part of royal insignia. A scepter is really nothing more than a simple staff, but the ones used in ceremony are usually highly decorated with precious metals and gemstones. The topping of a scepter varied in different countries and in different periods. In the Middle Ages two forms were distinguished: a long staff (baculum), otherwise called rod, and a short one (sceptrum), although their meaning was identical. The long staff, topped with a globe, is a typical attribute of God in Carolingian painting. A scepter could be crowned with three leaves or a lily, a globe, a bird, etc.

Sedimentary: Rock formed by layers of material that has accumulated and hardened over time.

Seed bead: (also seed-bead, seedbead). Mass produced tiny glass or plastic beads made by slicing tubes into tiny evenly spaced pieces. This makes them oblong in shape, rather than round, and flat on the ends. Seed beads can be strung together to make a necklace or bracelet, but are commonly used as spacers for larger beads. They can also be strung on a loom to make beaded bands and belts.

Seed Pearl: A very small pearl or imitation pearl popular during the Victorian period as accents set into gold jewelry or woven into long fringed necklaces called sautoirs.

Semi-Mount/Semi-Mounting: A finished piece of jewelry already embellished with gemstones and/or engraving that is simply waiting for the center stone. Pieces are sold this way to allow the buyer to add a center stone of their own choosing.

Silica: Crystalline silica is the scientific name for a group of minerals composed of silicon and oxygen. The term crystalline refers to the fact that the oxygen and silicon atoms are arranged in a three-dimensional repeating pattern.

Silicate: Any of a large group of minerals, forming over 90 percent of the earth’s crust, that consist of Silicon, oxygen, and one or more metals, (and sometimes hydrogen).

Silicon: A nonmetallic element which is only found as a compound with other elements in nature. When artificially extracted, silicon appears as a dark brown amorphous powder, or as a dark crystalline substance with a metallic luster. This substance is used in combination with other materials in glass, semiconducting devices, concrete, brick, refractories, pottery, and silicones. Its oxide is Silica, or common quartz, and in this form, or as silicates, it is the second most abundant element in the Earth’s crust, next to oxygen, making up 25.7% of it by weight.

Silver has a lustrous white color but needs polishing occasionally because silver reacts with Sulfur in the air to cause tarnishing. It is harder than gold and much more plentiful, but still too soft in its natural state to be of much use as jewelry without being alloyed with a harder metal. (see Sterling Silver). Silver has the highest thermal and electrical conductivity of the metals and is widely used in coinage, photography, dental and soldering alloys, electrical contacts, and printed circuits.  During the 18th and 19th century most of the worlds coins were struck of copper, bronze, gold or silver.

Silver tone: Jewelry finished with a silver color with very little appreciable measurement of weight in Silver.

Smoky topaz: see Smoky Quartz.

Snap bar closure: The hinged bar on the back of a lever back or omega back earring.

Snake chain: Unlike most chains which are a series of linked rings, a snake chain is made up of round wavy metal rings joined side by side forming a flexible tube with a smooth scaly texture like snake skin.

Snow Quartz: see White Quartz.

Soda: Any of various forms of Sodium carbonate used in making soap, powders, glass, and paper.

It has varying degrees of white veins of calcite and an occasional speck of pyrite.

Sodium: A common soft, waxy, light, extremely malleable silver-white unstable metallic element of the alkali group. It is always found as a compound with other elements in nature, such as common Salt, albite, etc. Sodium burns with a yellow flame, and is so readily oxidized that it combines violently with water and to be preserved must be kept under petroleum or some similar liquid.

Soldering: A technique used in making and repairing jewelry whereby two pieces of metal are joined by applying a molten metal which has a lower melting point than the two metals being joined.

Solitaire: A single, (solitary), gemstone mounted in a simple Setting, often found in a ring or pendant.

Sparkle: A measure of the light reflected out by a diamond or stone as it is viewed from different angles.

Spessartite: A red to brownish-red garnet composed of alumina manganese.

Spinel: Probably named from the Latin word “spina”, (meaning “thorn”), for its pointed crystals, spinel is a hard mineral with octahedral crystals occurring in igneous and carbonate rocks. It consists essentially of alumina and magnesia, but commonly contains iron and sometimes also chromium. It is found in a variety of colors including blue, green, brown, black, and the valuable red variety which resembles a ruby. It was popular in medieval jewelry.

Split Ring: Most commonly used for key-rings, a split ring is simply a metal ring with a “split” around its circumference. The split has an opening to the side of the ring at each end to allow a key or other small ring to slide into the slit and be pulled around the circumference of the ring until it reaches opening at the other end of the split.

Spray Brooch: A type of brooch, usually worn at the shoulder, which is characterized by floral themes featuring long stemmed jeweled flowers and long leaves.

Spring ring clasp: A very common kind of clasp used for joining two ends of a necklace. The clasp itself consists of a hollow metal tube in a circle shape with a gap in the side. The hollow tube contains a small wire held in place by a spring inside the tube behind the wire. The wire can be pulled back by means of a small knob which slides along the outer edge of the circular tube. Releasing the knob allows the spring to push the wire forward closing the gap. The other end of the necklace terminates in a small ring. By using the knob on the spring ring to open the gap in the hollow circular tube, one can then place the small ring through the gap and close the wire through the ring securing it in place and closing the necklace.

Square cut: A style of gem cutting resembling the emerald cut.

Square setting: A square shaped Setting with a prong at each corner.

Squash Blossom Necklace: A traditional piece of Navajo jewelry based on an old and favored Spanish-Mexican ornament which was actually not a squash, but a stylized version of the pomegranate.

Sterling Silver Ring


Like gold, Silver can be alloyed with other metals to improve its durability. Sterling silver is the industry standard containing 925 parts Silver and 75 parts of another metal, usually copper. Sterling silver can be used to plate other metals  With jewelry its lustrous white color adds a complementary fresh light to the complexion of the wearer.

Sterling Silver jewelry care and cleaning: The pieces that you wear frequently need very little care, but if the Sterling is stored for a length of time it may need polishing occasionally because silver reacts with sulfur in the air which causes it to tarnish. There is sulfur in egg, so if you spill egg on your silver necklace it may discolor the silver. Any discoloration or tarnish can be removed with a silver polish found in the hardware store or a silver cloth from the supermarket.  Always read the instructions before use and rinse the jewelry well with water (preferably filtered) and a little mild dishwashing soap, rinse again in clear water and dry well with a soft cloth.

For sterling silver chains and other solid sterling jewelry that does not have stones in it, here is the easiest and best way to make it shine and gleam.  Take a heat resistant glass bowl, line it with aluminium foil (kitchen foil) place your sterling silver on top of the foil.  Sprinkle with sodium bicarbonate (baking soda). Depending on how much you are cleaning  – about a tablespoon full. Now pour boiling water over this and it will bubble up.  Just leave it for about 10 minutes. Remove the jewelry and rinse it with clean preferably filtered water, lay it on a soft cloth and allow to dry. You now have sparkling chains etc. All between the links will be nice and clean,  Simple, economical and no harsh chemicals. If the item was very dirty I have found that after the above procedure it may be necessary to wipe it over with a silver cleaning cloth and the tarnish will come of quite easily. Possibly the best way to store silver jewelry is in airtight plastic or cellophane bags as it is the elements in the air that will cause tarnish.

Store jewelry separately in plastic pouches or soft cloth bags or original boxes to keep them from being scratched by contact with other items and to protect them from exposure to harsh daily elements.  Silver can be damaged by exposure to common cleaning solutions such as bleach, ammonia, or chlorinated water.  Best advice is to be radiant and wear it often.

Stick Pin: A pin with an ornament on the top worn vertically on a scarf, tie, or lapel. Also called a “tie pin” or “lapel pin”

Stippled finish: A texture formed by a series of pricks made with a steel punch.

Strass: A brilliant glass with high light refraction and exceptional iridescence, (essentially consisting of a complex boroSilicate of lead and potassium), used to manufacture artificial gemstones. Named after its inventor, a German jeweler, F. Stras. See also Rhinestone.

Stud: A simple style of earring for pierced ears that has a single stone (such as a pearl) or metal ball on a straight post with no dangling parts. (See also Button earring).

Sulfate: A Salt containing Sulfur dioxide.

Sulfur: An abundant, pale yellow, a nonmetallic element used in black gunpowder, rubber vulcanization, the manufacture of insecticides and pharmaceuticals, and in the preparation of sulfur compounds such as hydrogen sulfide and sulfuric acid.

Sulphur: A variant spelling of Sulfur.

Sunstone: A variety of oligoclase which can be transparent or translucent and varies in color from golden to orange to red-brown. Sunstone glitters due to hematite or goethite crystals suspended in the stone. It can be found in Canada, Oregon, India, Norway, and Russia. Sunstone is brittle and has a hardness of 6 on the Mohs scale.

Swing Center: The central decorative motif of pendant earrings which is free to move and swing, it is suspended within a similarly shaped frame.

Symmetry: How similar one side of an object is to the other side. The lengths and angles on each side of a faceted gemstone are closely compared. The more uniform the cut, the higher the value of the stone.

Synthetic: Gemstones produced in a laboratory rather than found in nature. Synthetic gemstones are not “fake”, since they have exactly the same chemical characteristics as the natural stone, but they are usually flawless and much cheaper than the real thing. The most common synthetic gems are emeralds, rubies, sapphires, and opals.
