The agate was named after its most common place of discovery, the Achates River in Sicily.

Alexandrite is a truly phenomenal gemstone due to its distinct color change from red to green. Without this

Amazonite can be assigned to a larger group of gemstones: the feldspar group. There is a wide variety of feldspars with many different colors and appearances. It can therefore be divided again into two subgroups: the potassium feldspar and the plagioclase. Amazonite is a potassium feldspar.

Amethyst belongs to the family of macrocrystalline (consisting of large crystals) quartz, such as citrine or rose quartz. Amethyst's color ranges from light lilac to deep purple and is produced by the trace element iron.

The term "ametrine" is made up of "amethyst" and "citrine" and thus refers to the two gemstones that come together in ametrine.

The connection to the sea is already clear from the name: "Aquamarine" literally means "water of the sea" and is made up of the Latin words "aqua" (water) and "marinus" (belonging to the sea).

Amber is fossilized tree resin that was formed between 2 and 50 million years ago. Because it is made from tree resin, amber is classified as an organic gemstone.

The citrine is named after the French word for lemon: "Citron", which describes its lemon-yellow colour. This living gemstone is a macrocrystalline variety of quartz, commonly found in nature with amethyst. The citrine gets its bright color from iron. The multicolored citrine is a combination of citrine and white quartz.

"Diamond" comes from the Greek word "adamas", which means something like "invincible" and emphasizes the special hardness of this gemstone.

The diopside received its name in 1806 from the French mineralogist Hauy and is derived from the Greek "dis" for double, "ospis" for sight and "idos" for shape. Diopside is a common mineral from the mineral class of silicates. It is a rock-forming mineral found in basic and ultrabasic rocks such as peridotite and gabbro. It crystallizes in the monoclinic crystal system and develops short to long, prismatic crystals but also granular aggregates.

The name "garnet" probably comes from the Latin term for "grain" and thus alludes to the rounded shape of raw gemstones found. It is also partly assumed that the name indicates the visual similarity to the red fruits of the pomegranate tree. There are garnets in many more colors than just red. The term garnet refers to more than 10 different groups of gemstones with a similar chemical composition.

Iolite, also called cordierite, and obsolete dichroite, is a common mineral from the mineral class of silicates. Because of its beautiful violet-blue color, which is often compared to light blue sapphire, iolite is sometimes called "water sapphire".

Deeply rooted in Chinese culture, jade is considered a royal gemstone that has been used since 6,000 BC. in China.

Kunzite is a gemstone with a short history, first discovered in 1902 in the Pala District of San Diego County, California. Since then, he has enchanted every beholder with his feminine shades. Kunzite was named after its discoverer, George Frederick Kunz, a famous Swiss gemologist and Tiffany collaborator. He first discovered it in 1902 in California, USA.

The moonstone got its name from its shimmer, reminiscent of the moonlight. This shimmering is called "adularescence" in technical jargon, because it always appears different when the stone is moved. That is why it is primarily characterized by its bluish-white shimmer.

Morganite is another beautiful variety from the beryl family that shines in enchanting shades of pink to violet. Morganite was first discovered in Madagascar in 1911 and was initially called "pink beryl".

Onyx is an opaque to slightly translucent, two-toned black and white layered, fibrous variety of chalcedony, which in turn is a variety of the mineral quartz. With onyx, black and white layers alternate with each other. Pure black chalcedony is also known as onyx. Other two-tone banded varieties are the sardonyx with brown and white banding and the carnelian with red and white banding. Since the brown of the sardonyx often blends into the black, it is often difficult to distinguish between onyx and sardonyx.

Opal comes from the Latin "opalus" which in turn derives from the Greek "opallios" meaning "to see a change".

The peridot only occurs in shades of green, so it is a gemstone of its own color or idiochromatic and belongs to the group of silicates. It gets its different shades of green from the element iron. The trace elements chromium or nickel can make the color appear even more intense. Occasionally, a cat's-eye effect (“chatoyance”) occurs, an effect in which the reflection of a single ray of light appears on the surface of the gemstone, caused by long needle-like inclusions. The classic source is the island of Zeberget. The world's largest deposit, on the other hand, is in the San Carlos Apache Reservation in Arizona, America. Other mining areas are in China and Pakistan.

The well-known quartz family of minerals produces some beautiful gemstones that, while visually distinct, are classified into this one group based on their chemical makeup.

Rhodolite is the name for a mixed crystallization between pyrope and almandine.

The name ruby comes from the Middle Latin word "rubinus" = ruby (red stone), or from the Latin "ruber" = red. In Sanskrit the ruby is called "ratnarai", which means "king of gems".

In a broader sense, sapphire is any precious stone made of corundum, with the exception of the ruby-red varieties (rubies).

The name "emerald" comes from the Greek word "smaragdos", which means "green gem".

The name spinel either comes from the Greek and means "spark, sparkle" or it could come from the Latin "spina" = tip, since the spinel usually crystallizes as an octahedron, and this has 6 tips.

The name "Tanzanite" was introduced by the jewelry company Tiffany & Co New York and refers to the origin of the gemstone: Tanzania.

Topaz takes its name from an island in the Red Sea, which in ancient times was called Topazos. In fact, another mineral, olivine, which was long confused with topaz, was mined there. Another explanation of the name traces it back to the Sanskrit word tapas, meaning "fire" or "shining".

Green tsavorite comes from the colorful garnet family of gemstones.

The modern name "turquoise" is somewhat of a misnomer: when Venetian traders brought the gemstone to France, it was called "pierre turquois" for "Turkish stone", although it does not come from Turkey at all, but from Persia. However, he does not bear this name from the beginning: in Persian he is referred to as "ferozah", which means "victorious". Until the 13th century, the name "calläis" for "beautiful stone" was common in Europe, probably derived from the ancient gemstone names "kalláïnos" (Greek) or "callaina" (Latin). Some mineralogists and authors suspect that these designations refer to our present-day turquoise, but this view is not without controversy.

Even its name refers to the variety of colors: "Tourmaline" is derived from the Sinhalese term "turmali" for "stone with mixed colors". It is also referred to as the "chameleon gemstone", not only because of the variety of its colors, but also because of its historical confusion with other gemstones.

The name zircon comes from either the Arabic "Zargun" (cinnabar) or the Persian "Zargun" (gold-colored). However, it is also said that it takes its name from the chemical element zirconium.
