Types of Gemstones are known for their beauty, rarity, and value. They have been used by humans for thousands of years as ornaments and jewelry, and as symbols of power, wealth, and protection. These stones are composed of natural minerals and require thousands of years to form under specific geological conditions, including pressure and heat.
Understanding Gemstone Classifications
Gemstones are distinguished by their beauty and rarity, and are mainly divided into natural gemstones, synthetic gemstones, and organic gemstones, To learn how to differentiate between real and fake gemstones, check out our comprehensive guide to identifying genuine gemstones.
Each has its own distinct properties and formation process, as follows:
Precious Gemstones
- Properties: The undisputed king of the gem world, it is one of the oldest, rarest, and most valuable gemstones. Its exceptional hardness (10 on the Mohs scale) and brilliant luster make it ideal for everyday wear.
- Colors: It is found in a wide range of colors, from colorless to transparent black, and rare and valuable colors such as blue, yellow, and pink are also available.
Semi-Precious Gemstones
- Properties: Known for its stunning purple color, it belongs to the quartz family.
- Importance: Associated with spirituality and relaxation, it is said to help calm the mind and reduce stress.
Organic and Synthetic Gemstones
- Synthetic gemstones are gemstones created in laboratories using advanced technologies, but they possess the same chemical, optical, and physical properties as the corresponding natural gemstone. For example, a synthetic diamond is a real diamond from a chemical and physical perspective, but it was not formed within the Earth.
- Organic gemstones are gemstones composed of organic materials—that is, they are produced by, or were part of, living organisms. They differ from mineral gemstones, which are formed through long geological processes within the Earth.
Detailed Profiles of Popular Gemstones

These stones are used in jewelry, decoration, and even in some industrial applications. Here is an overview of some of the most famous: diamonds, rubies, emeralds, sapphires, and amethyst:
Diamond
Diamond is the hardest known natural material, composed entirely of carbon atoms in a crystal lattice. This unique structure accounts for its exceptional hardness (10 on the Mohs scale) and resistance to scratching and abrasion.
Sapphire
Sapphire is a precious gemstone belonging to the corundum group, which is aluminum oxide. It is characterized by its luster and high hardness (9 on the Mohs scale).
Emerald
Emerald is a green gemstone, a type of beryl mineral colored with trace amounts of chromium or vanadium.

Factors to Consider When Choosing a Gemstone
When choosing a gemstone, there are several factors to consider to ensure you get a stone that meets your expectations and suits your needs. Here are the most important of these factors:
Color and Clarity
- Color: Color is the most important factor in a gemstone’s value. Look for a rich, vibrant, and evenly distributed color. Rare and intense colors are typically more valuable.
- Clarity: Refers to the presence or absence of internal (internal flaws) or external (surface blemishes). The fewer inclusions, the higher the value of the stone.
Hardness and Durability
- Hardness: Measured on the Mohs scale, it refers to a stone’s resistance to scratching. Harder stones such as diamonds, rubies, and sapphires are excellent choices for everyday wear.
- Toughness: It refers to a stone’s resistance to breaking or cracking when exposed to impact.
Symbolism and Personal Significance
You should choose a stone that you personally like and that suits your taste. Color, shape, and size are all personal matters.
Caring for Your Gemstone Jewelry
Gemstone jewelry is a valuable investment and a unique piece of art, but to maintain its luster and beauty over the years, it requires special care. Care methods vary depending on the type of gemstone and jewelry metal. Here’s an overview of the most important aspects of care:
Cleaning and Storage Tips
- Hard gemstones (such as diamonds, rubies, emeralds, and sapphires): These can usually be cleaned with warm water, a mild soap (such as dish soap), and a very soft brush to remove dirt. Rinse thoroughly and dry with a soft, lint-free cloth.
- Separate Storage: Store each piece of jewelry separately in a soft cloth pouch or lined jewelry box. This prevents scratches and friction between different pieces, especially between hard and softer stones.
Regular Maintenance and Inspections
- Professional Inspection: It is recommended to take your jewelry to a professional jeweler for inspection and professional cleaning at least once a year. The jeweler can detect and fix any potential problems before they worsen, and clean the jewelry using specialized tools and materials.
- Repolishing: The jeweler can also re-polish precious metals to maintain their luster.
Professional Services
- Pearls: Very sensitive to perfumes, hairspray, and cosmetics. Wear them after applying makeup. Wipe them with a soft cloth after each wear.
- Opals: Sensitive to dryness and sudden changes in temperature, which can cause them to crack.
- Turquoises: Porous and easily absorb oils and chemicals, which can alter their color.
- Emeralds: Often riddled with natural inclusions and cracks, making them more fragile. Avoid ultrasonic cleaners.
