When recently shopping for jewelry, I noticed that some sellers were using the terms 'crystal' and 'gemstone' interchangeably. By understanding the difference between a crystal and a gemstone, shoppers can make informed decisions about what they are purchasing and how to determine the quality. Let's take a closer look at each of these terms. We will also define 'minerals', since you often hear this term relating to crystals and gemstones.
Minerals
Minerals are naturally occurring inorganic solids that have a specific chemical composition and crystal structure. They are the building blocks of rocks and can be found in a wide variety of forms and shapes. Minerals have a range of physical and chemical properties, such as color, hardness, density, and cleavage, and they have many practical uses in various industries, such as construction and electronics. Examples of minerals:
Fluorite (a colorful & used in making glass and jewelry)
Galena (an important ore with lead and silver, used in batteries and bullets)
Halite (a common rock salt used in cooking and de-icing)
Hematite (a metallic mineral used as a pigment & for jewelry)
Pyrite (also known as "fool's gold," with a metallic appearance)
Crystals
Crystals are solids that have a repeating, ordered arrangement of atoms, ions, or molecules in them. They can be made from a variety of materials, including minerals, metals, and chemicals. Crystals can be natural or synthetic and have various properties, such as transparency, color, and durability. They have many applications in our daily lives, such as in jewelry, electronics, and optical devices. Examples of crystals:
Ammolite (iridescent crystal formed from fossilized ammonites, used in jewelry & art)
Celestite (a blue crystal used in spiritual practices & as a decorative mineral)
Citrine (a yellow to brown crystal of the quartz family, often used in jewelry)
Malachite (a green banded crystal used in decorative objects & jewelry)
Gemstones
Gemstones are minerals or rocks that are valued for their beauty, rarity, and durability. They come in a wide range of colors and shapes and have been used for thousands of years as decorative and symbolic objects. Gemstones are commonly used in jewelry, but they can also have other uses, such as in healing practices and spiritual traditions. Examples of gemstones:
Amethyst (a purple variety of quartz, often used in jewelry)
Diamond (a clear or colored gemstone valued for its brilliance and hardness)
Jade (a green mineral often carved into decorative objects and jewelry)
Lapis lazuli (a blue gemstone with white and gold flecks, often used in jewelry and art)
Moonstone (a milky white gemstone with a blue sheen, often used in jewelry)
Ruby (a red gemstone, one of the most valuable and sought after)
Sapphire (a blue gemstone, highly valued for its color and durability)
Tanzanite (a blue-violet gemstone found only in Tanzania, often used in jewelry)
It's important to note that while all gemstones are minerals, not all minerals are gemstones.
Example: a mineral that is not a gemstone is feldspar, which is a group of rock-forming minerals that are commonly found in igneous, metamorphic, and sedimentary rocks. Although feldspar has many industrial uses, it is not typically considered a gemstone due to its lack of aesthetic value.
All gemstones are also crystals, although not all crystals are gemstones.
Example: a crystal that is not a gemstone is salt (halite). While salt crystals can be used for decorative purposes, they are not considered gemstones because they are not valued for their beauty or rarity.
How to Determine the Quality of a Gemstone or Crystal
Now that we know the difference between a gemstone and a crystal, let's talk about how to evaluate the quality of each. When shopping for a gemstone or crystal, there are a few factors to consider:
Color: The color of a gemstone or crystal can greatly affect its value. The most valuable gemstones and crystals have a rich, vibrant color that is evenly distributed throughout the stone. Stones with dull or uneven color are generally considered to be of lower quality.
Clarity: The clarity of a gemstone or crystal refers to how free it is from inclusions, or internal flaws. Inclusions can greatly affect the appearance and value of a stone. The most valuable gemstones and crystals are nearly flawless, with few or no visible inclusions.
Cut: The cut of a gemstone or crystal refers to its shape and the way it has been faceted. A well-cut stone will have a symmetrical shape and will reflect light in a pleasing way. Poorly cut stones can look dull and lifeless.
Carat weight: The carat weight of a gemstone or crystal refers to its size. Larger stones are generally more valuable than smaller ones, all other factors being equal.
Rarity: The rarity of a gemstone or crystal can greatly affect its value. Gemstones and crystals that are rare or difficult to find are generally more valuable than those that are more common.
Evaluating Pricing
Once you have determined the quality of a gemstone or crystal, it's important to evaluate pricing to ensure that you are getting a fair deal. Here are some tips to keep in mind:
Research: Before making a purchase, do some research to get an idea of the typical price range for the type of stone you are interested in. You can look up pricing guides online or consult with a reputable gemologist.
Shop around: Don't be afraid to shop around and compare prices from different sellers. Keep in mind that the cheapest option may not always be the best quality.
Ask questions: If you have any doubts about the quality or pricing of a stone, don't hesitate to ask the seller questions. A reputable seller should be able to provide you with information and answer any concerns you may have.
Consider the source: If you are purchasing a rare or valuable stone, it's important to consider the source. Stones that are ethically sourced and have a clear chain of custody are generally considered to be of higher value.
By following these tips, you can make an informed decision when purchasing a gemstone or crystal and ensure that you are getting a fair deal. Remember, the most important thing is to choose a stone that speaks to you and brings you joy.
