Crystals: meaning, definitions and examples

Use this term when referring to natural or synthetic substances with a unique geometric shape formed by the orderly arrangement of atoms. Often discussed in science, jewelry, and metaphysical contexts.

• She admires the intricate crystals forming in her geode collection
• Quartz crystals are often used for their healing properties

Similar to 'gems', but slightly more technical. Used when discussing types of minerals that can be cut and polished for use in jewelry or decoration.

• The jeweler showed us various gemstones, including rubies and sapphires
• Collectors often look for rare gemstones

Appropriate in scientific and educational contexts when referring to naturally occurring substances that have a definite chemical composition and crystalline structure. Used broadly in geology and chemistry.

• Scientists study minerals to understand the Earth's composition
• Feldspar is one of the most common minerals in the Earth's crust

General term for naturally occurring solid mixtures of minerals or mineraloids. Used in everyday language, education, and geology.

• Children love to collect interesting rocks from the garden
• Geologists examine rocks to learn about Earth's history

General term for naturally occurring or synthetic solid substances with a regular, repeating atomic structure. Commonly used in scientific contexts or when referring to a variety of these substances collectively.

• Crystals can form in geodes over thousands of years.
• Many people believe that crystals have healing properties.

Refers to precious or semi-precious stones that have been cut and polished for use in jewelry. Used when discussing jewelry, high-value items, or collector's pieces.

• The museum displayed a collection of rare and valuable gems.
• She inherited a ring set with several exquisite gems.

Another term for valuable and often rare stones that are used in fine jewelry. Similar to 'gems' but emphasizes the value and rarity. Often used in more formal contexts.

• Diamonds, emeralds, and rubies are among the most well-known precious stones.
• The royal crown is encrusted with numerous precious stones.

Refers specifically to small, shaped pieces of crystal used in jewelry making, decoration, or crafts. Best used when talking about accessories or handmade goods.

• She bought a necklace adorned with beautiful crystal beads.
• The artist fashioned intricate bracelets from colorful crystal beads.

Used in everyday language to refer to solid substances where atoms are arranged in an orderly pattern. Common in contexts like jewelry, natural minerals, and healing practices.

• She collects crystals for their unique colors and shapes.
• Many people believe that crystals have healing properties.

Used in a general sense to refer to any solid state of matter, not necessarily implying an orderly arrangement of atoms. Suitable for everyday conversation and general descriptions in science and engineering.

• Ice and metal are typical examples of solid forms.
• The substance exists in both liquid and solid forms depending on the temperature.

Used in scientific and technical contexts to describe the precise arrangement of atoms or molecules in a solid. Often used in chemistry, physics, and materials science.

• The crystalline structures of minerals can vary based on their chemical composition.
• Scientists study crystalline structures to understand how materials behave under different conditions.

Used primarily in physics and materials science to describe the 3D grid-like structure of atoms or molecules within a crystal. This term is technical and specific, often used in academic and research settings.

• Quantum mechanics can predict the behavior of particles within these lattice arrangements.
• Defects in lattice arrangements can significantly alter the properties of materials.
