Have you ever wondered what those sparkling crystals are made of and how they form? Growing your own crystals is an enriching, hands-on hobby that allows you to produce beautiful formations with many uses and benefits. In this beginner’s guide, we’ll explore the magical world of crystal growing and identify the best crystals you can easily grow at home.
An Introduction to Crystals
Crystals are solid minerals made up of atoms, molecules, or ions arranged in an orderly, repeating 3D pattern. The word “crystal” comes from the Greek word “krystallos” meaning clear ice.
While crystals can form naturally underground through geological processes over thousands of years, synthetic crystal growing lets you produce perfect specimens in a matter of days or weeks.
The earliest recorded crystal growth experiment was detailed by Sir Isaac Newton in 1664. Today crystal growing is a popular educational and fun DIY project. Crystals are used in various industries from semiconductors to jewelry. Many also believe crystals have healing or spiritual properties.
Types of Crystals
There are several ways to classify crystals:
Natural vs Synthetic
- Natural crystals form without human intervention through natural geological processes. Natural crystals can take thousands of years to form underground and have irregular shapes.
- Synthetic crystals are manufactured under controlled lab conditions to create perfect crystalline structures. Synthetic crystals grow much quicker than natural ones.
Organic vs Inorganic
- Organic crystals come from substances with carbon such as proteins or amino acids. Organic crystals include crystals formed from urea or glycine.
- Inorganic crystals do not contain carbon but are made up of mineral salts. Common examples are crystals of sodium chloride or copper sulfate.
How Do Crystals Grow?
Crystal growth depends on several key factors that must be carefully controlled:
Temperature
The rate of crystal growth increases with temperature as atoms and molecules move faster in warmer solutions. However, impurities also increase at higher temperatures which can distort the crystal lattice.
Concentration/Supersaturation
A supersaturated solution contains more dissolved solute than normal at a given temperature. Supersaturation provides the driving force for molecules to come out of solution and crystallize.
Solvent
The solvent provides a medium for the solute molecules or ions to move and rearrange into a crystal lattice. Water is the most common solvent but others like acetone can also be used.
Seed Crystal
A tiny piece of the crystal material acts as a template for further growth in an ordered pattern. The seed crystal’s molecular structure is replicated as more molecules attach.
Pressure
Increased pressure keeps solute molecules closer together so crystallization occurs more readily. Pressure vessels are used for commercial crystal growing.
The Best and Most Popular Crystals to Grow at Home
Now that we understand how crystals form, let’s look at some of the best and most popular crystals you can easily grow at home:
Clear Quartz Crystals
Clear quartz is one of the most common and readily available crystal types. It has a vitreous luster and hexagonal prismatic shape. Silicon dioxide is the chemical formula.
How to grow: Mix 1 part sodium silicate solution to 3 parts distilled water. Pour into a jar with a seed crystal and screw on the lid. Place it in a warm spot at 75-85°F. Crystals form within 1-2 weeks.
Uses: Clear quartz crystals are used for their piezoelectric properties. They are also popular for spiritual healing and meditation.
Copper Sulfate Crystals
Copper sulfate forms beautiful blue triclinic crystals. The chemical formula is CuSO4. Copper sulfate solutions have a bright blue color.
How to grow: Mix 20 g copper sulfate powder in 100 ml boiling water until fully dissolved. Pour into a glass jar with a copper wire or crystal fragment. Cool slowly to room temperature.
Uses: Copper sulfate crystals are sold as fungicides and used to make other copper compounds. The striking blue color is used in decorative crafts.
Epsom Salt Crystals
Epsom salt is hydrated magnesium sulfate with the chemical formula MgSO4·7H2O. The crystals are formed when magnesium sulfate powder is dissolved in water.
How to grow: Stir 2-3 tablespoons of Epsom salts in 1 cup hot water until fully dissolved. Pour the solution into a glass dish, jar, or bowl and let it stand undisturbed overnight. Large crystals will form as the water evaporates.
Uses: Epsom salt crystals are used to soothe aches and pains. They have many household and gardening uses too.
Sugar Crystals
Table sugar has the chemical name sucrose and formula C12H22O11. Dissolving and recrystallizing sucrose creates large sparkling sugar crystals.
How to grow: Heat 1 cup water and stir in as much sugar as possible until saturated. Allow to cool slightly and pour into jars with sticks or strings as seed crystals. Cover with perforated lids. Crystals grow in 5-7 days.
Uses: Sugar crystals can decorate cakes and candy. They are also used as abrasives for exfoliating skin. Kids love growing sugar crystals for science experiments.
Borax Snowflake Crystals
Borax is sodium tetraborate decahydrate with the formula Na2B4O7·10H2O. It crystallizes into beautiful whimsical shapes that resemble snowflakes.
How to grow: Mix 1 cup hot water with 1-2 tablespoons of borax powder until fully dissolved. Add 2-3 drops of food coloring if desired. Pour into containers and poke sticks halfway down. Let it cool for crystals to appear on the sticks.
Uses: Borax crystals make amazing ornaments. Borax is used as a cleaning booster and fungicide. The crystals also have applications in chemistry experiments.
The Healing Properties of Crystals
Many believe that crystals emit beneficial energy fields that can heal the mind, body, and spirit. While scientific evidence is limited, thousands of people use crystals in spiritual practices. Some commonly used healing crystals are:
Quartz
- Clear quartz – amplifies energy
- Rose quartz – promotes love
- Smoky quartz – relieves stress
Aventurine
- Green aventurine – prosperity and luck
Agate
- Moss agate – self-confidence and harmony
Other Healing Crystals
- Chrysocolla – communication
- Malachite – emotional balance
- Tiger’s eye – focus and insight
- Selenite – clarity and truth
Healing crystals are usually kept on the body as jewelry or placed around the home. Many also meditate with crystals.
The Spiritual Meaning Behind Crystals
Beyond physical healing, crystals are traditionally used to open up spiritual awareness and bring positive energy into someone’s life. Different crystals have various properties based on their structure and origins. Some examples:
- Amethyst – A common protective crystal that blocks negative energy and promotes spiritual growth. Also brings wisdom, calm, and focus.
- Citrine – The “success stone” that encourages prosperity. Its golden color represents vitality and abundance.
- Obsidian – Provides spiritual grounding as a black protective stone. Helps clear subconscious blocks.
- Clear quartz – A master healer and amplifier crystal. Enhances clarity and intuition.
- Rose quartz – Known as the love crystal. Opens up the heart chakra to attract friendship, affection, and closeness.
