Quartz: Quartz refers to a family of crystalline gemstones of various colours and sizes. Among the well-known types of quartz are rose quartz (which has a delicate pink colour), and smoky quartz (which comes in a variety of shades of translucent brown). A number of other gemstones — like Amethyst and Citrine — are also part of the quartz family. Rutilated quartz is a popular type of quartz containing needle-like inclusions.

Silversmiths, goldsmiths, and lapidaries methods include forging, casting, soldering or welding, cutting, carving, and "cold-joining" (using adhesives, staples, and rivets to assemble parts).Diamonds:Diamonds were first mined in India. Pliny may have mentioned them, although there is some debate as to the exact nature of the stone he referred to as Adamas; In 2005, Australia, Botswana, Russia and Canada ranked among the primary sources of gemstone diamond production.

Some gems, for example, amethyst, have become less valued as methods of extracting and importing them have progressed. Some man-made gems can serve in place of natural gems, an example is the cubic zirconia, used in place of the diamond.

Impact on society: Jewellery has been used to denote status. In ancient Rome, for instance, only certain ranks could wear rings; Later, sumptuary laws dictated who could wear what type of jewellery; again based on rank. Cultural dictates have also played a significant role; for example, the wearing of earrings by Western men was considered "effeminate" in the 19th and early 20th centuries.

The British crown jewels contain the Cullinan Diamond, part of the largest gem-quality rough diamond ever found (1905), at 3,106.75 carats (621.35 g). Now popular in engagement rings, this usage dates back to the marriage of Maximilian I to Mary of Burgundy in 1477. Other gemstones:Many precious and semiprecious stones are used for jewellery. Among them are:

By the mid 1940s, 85% of weddings in the U.S. featured a double-ring ceremony, up from 15% in the 1920s. Religion has also played a role: Islam, for instance, considers the wearing of gold by men as a social taboo, and many religions have edicts against excessive display.

Ruby: Rubies are known for their intense red colour, and are among the most highly valued precious gemstones. Rubies have been treasured for millennia. In Sanskrit, the word for ruby is “ratnaraj”, meaning “king of precious stones.”

Jade: Jade is most commonly associated with the colour green, but can come in a number of other colours as well. Jade is closely linked to Asian culture, history, and tradition, and is sometimes referred to as the “stone of heaven.”
