What are Rocks and Gemstones?

At their core, rocks are naturally occurring solid aggregates of one or more minerals or mineraloids. They form the Earth’s crust and are classified based on their origin: igneous, sedimentary, and metamorphic. Igneous rocks, like granite and basalt, form from the cooling and solidification of molten rock (magma or lava). Sedimentary rocks, such as sandstone and limestone, are formed from the accumulation and cementation of mineral and organic particles. Metamorphic rocks, like marble and slate, are formed when existing rocks are transformed by heat, pressure, or chemical reactions.

Gemstones, on the other hand, are typically mineral crystals that possess beauty, durability, and rarity, making them suitable for use in jewellery and other adornments. While many gemstones are mineraloids like opal, most are specific mineral species like corundum (ruby and sapphire), beryl (emerald and aquamarine), and quartz (amethyst and citrine). The value of a gemstone is determined by the “4 Cs”: cut, color, clarity, and carat weight. The unique geological conditions required for their formation contribute to their rarity and desirability. For industrial applications, the hardness, chemical stability, and specific properties of certain minerals and rocks are paramount.
