Quartz is silicon dioxide (SiO₂)—one of the most common minerals in Earth’s crust and the head of an entire family of stones that includes amethyst, citrine, rose quartz, and smoky quartz. In this guide, we explain what quartz is, how it forms, and how much it costs, as well as how to distinguish natural stone from glass and which variety to choose for yourself.
What is quartz and how does it form?
The mineral quartz forms granite, sandstone, and river gravel, yet it can also create crystals more beautiful than many a gemstone. It most often crystallizes from hot solutions circulating through cracks in rocks: as the temperature slowly falls, silicon and oxygen atoms arrange themselves into six-sided prisms capped with pyramids. The process takes thousands, and sometimes millions, of years—so every quartz crystal is literally a record of Earth’s history.
The name of the purest variety comes from the Greek krustallos, meaning ice. The ancient Greeks and Romans believed that clear quartz was water frozen by the gods so deeply that it would never melt. In Egypt, it was carved into amulets protecting the soul in the afterlife; shamanic traditions in North America saw it as petrified light, while medieval fortune-tellers gazed into quartz spheres. Few stones have such a rich legend.
The properties and meaning of quartz
Let’s start with the facts. Quartz has a hardness of 7 on the Mohs scale, so quartz jewelry withstands everyday wear well and does not scratch easily—one of the reasons jewelers are so fond of it. As reported by the Mindat.org mineralogical portal, quartz also exhibits piezoelectric properties: when compressed, it generates an electric charge, which allows it to keep time in quartz watches and function in electronics.
The meaning of quartz in lithotherapy and esotericism is an entirely different story. Tradition considers it the most powerful “energy amplifier” among stones—it is believed to absorb, store, and release energy, restoring balance to the aura. This is a matter of belief, not science, but it is precisely what has made quartz a favorite talisman stone for centuries: transparent varieties are associated with clarity of mind, pink varieties with the heart, and dark varieties with protection and grounding.
Clouds, misty patches, and tiny scratches inside the stone are not flaws. They are natural inclusions—the fingerprint of nature and the simplest proof of authenticity. Thanks to them, no two quartz stones in the world are identical.
✨ Esoteric fact
It is believed that clear quartz can amplify the effects of other stones—when worn with amethyst or tourmaline, it is said to make their vibrations more pronounced.
Types of quartz and its colors
The quartz family is divided into two groups. Macrocrystalline varieties have crystals visible to the naked eye—these include rock crystal, amethyst, citrine, rose quartz, and smoky quartz. Cryptocrystalline varieties, such as agate, chalcedony, and jasper, are made up of microscopic grains.
Quartz colors, in turn, result from trace impurities of iron, titanium, manganese, or aluminum, as well as natural radiation in the rocks—which is why the same mineral can be pink, honey-colored, smoky, or black. Below are brief introductions to the most popular varieties; most are described in greater detail on separate pages.
Rose quartz
A powdery-hued stone of tenderness, whose color comes from trace amounts of titanium, iron, or manganese. Crystal healing associates it with the heart chakra, gentleness, and self-love—not only romantic love. Rings, necklaces, and bracelets featuring this stone can be found in the rose quartz jewelry collection.
Smoky quartz and morion
From misty beige through cognac to almost-black morion—the color of smoky quartz is the result of natural radiation to which the mineral was exposed for millions of years. In Scotland, where it was known as Cairngorm, it adorned dagger handles and was considered a warriors’ amulet; to this day, smoky quartz and its lighter shades are believed to ground and protect against negative energy. Elegant silver and gold settings can be found in the smoky quartz jewelry collection.
Milky quartz, white quartz, and rock crystal
The stone’s milky cloudiness is caused by microscopic bubbles of gas and water trapped during crystallization, while the completely transparent variety is known as rock crystal. In crystal healing, all of them are considered stones of cleansing, peace, and clarity of thought. We examine their subtle differences in detail in the article milky quartz – properties and meaning, while the transparent classic can be viewed in the Rock Crystal collection.
Rutilated and tourmalinated quartz
Sometimes golden rutile needles sparkle inside a transparent crystal—these are the famous “Venus’s Hair,” one of the most sought-after patterns in the world of gemstones. Black needles, on the other hand, are tourmaline: in crystal healing beliefs, tourmalinated quartz combines the purifying power of quartz with the protective energy of tourmaline. Such specimens resemble miniature landscapes enclosed in stone, and no two are ever identical.
Otherwise known as green quartz—the secret of aventurine and the glow of lemon quartz
Green is the color of life, abundance, and growth in the mineral world, which is why you ask us about green varieties of quartz particularly often. It is worth knowing that what is otherwise called green quartz is most often aventurine in jewelry—a quartzite that owes its shimmering green color (the phenomenon of aventurescence) to tiny inclusions of fuchsite, a green mica. So when you read about the properties of green quartz, it almost always refers to aventurine: it is believed to attract luck and prosperity and to help with making sound financial decisions.
Lemon quartz comes from the border between yellow and green, often produced by carefully heating amethyst in the presence of iron. Its juicy, lime-green hue radiates optimism—in lithotherapy, it is regarded as a stone of joy, creativity, and vitality, ideal for days when you are short on energy and creative inspiration.

How much does quartz cost?
The mineral itself is common, so compared with diamonds, sapphires, or rubies, quartz remains an affordable stone. That does not mean that all specimens cost the same—the price increases with the stone’s uniqueness.
The main factors affecting value are clarity (the absence of undesirable cloudiness in transparent varieties), color saturation—a vividly pink quartz will cost more than a very pale one—as well as carat weight and the precision of the cut, since beautifully faceted smoky or lemon quartz requires considerable skill from the cutter. The final price of the jewelry also depends on the setting: 925 sterling silver, gold, or platinum.
How to recognize real quartz?
The market is full of dyed glass and synthetic substitutes, but you can distinguish them with a few simple tests. Natural quartz feels cool to the touch and warms up noticeably more slowly than glass. Under a magnifying glass, glass gives itself away through perfectly round air bubbles, while natural inclusions have irregular shapes. And the most important rule: buy from a trusted source.
At Brazi Druse Jewelry, we are direct importers of minerals, so we personally stand behind the authenticity of every stone. You will find the entire family of varieties—from rock crystal to morion—in our quartz jewelry collection.
