Crystals are popular as decorations or for use in jewelry. Many people also use crystals in a spiritual way, as different crystal types are thought to have different healing abilities or purifying properties.
The value of crystals depends on the type of crystal, how rare it is, how in-demand it is, and what the hue, clarity, and depth of color are.
Clear Quartz
Quartz is a clear or milky white stone that’s relatively common. Because it’s so common, quartz is worth between $1 and $7 when cut. The price of the stone rises if it’s particularly clear and has few imperfections.
Fluorite
Fluorite or fluorspar is a type of calcium fluoride crystal. It can be clear, purple, or green and is available in a range of hues. Fluorite usually costs between $3 and $8 per carat.
For those who use crystals as a healing technique, fluorite is thought to reduce and absorb stress or negative energy. It’s also supposed to boost confidence and help in encouraging positive energy while improving decision-making.
Selenite
Selenite is a type of gypsum. It has a color similar to clear quartz, although it has a more pearly sheen. Selenite often forms in bars or wands, although larger pieces can also be found.
Large pieces are relatively rare, and most pieces of selenite cost between $5 and $45, depending on the size and clarity.
Amethyst
Amethyst is a beautiful purple gem that is actually a type of quartz. The value of amethyst varies depending on the depth of color and the clarity of the stone, but in general, the cost of 1 carat of amethyst is between $2 and $40. Most amethyst costs between $20 and $30 per carat.
Amethyst is considered a gemstone and is often used in jewelry, but it’s still one of the most affordable crystals because it’s relatively plentiful. It can also be produced synthetically, and synthetic stones often look just as beautiful as real stones.
The production of synthetic amethyst has drastically lowered the overall price of the gem, and synthetic stones cost much less than stones that have been mined.
Citrine
Citrine has a similar chemical makeup to amethyst and, in fact, amethyst that’s exposed to heat or light for a long period will take on the yellow or orange tint of citrine. Citrine is worth between $10 and $30 per carat, depending on the clarity and the intensity of the color.
Rose Quartz
Rose quart is similar to clear quartz, but it has a pink hue. This stone is relatively common, so most rose quartz sells for between $2 and $4 per carat. The stone is supposed to promote inner healing, feelings of peace, and self-love. It’s also often used as a symbol of recovering from grief.
Aventurine
Aventurine is another type of quartz. It has a more opaque appearance and can be gray, brown, red, blue, or orange, but the most common and most popular color is green. Aventurine usually sells in small pieces for between $3 and $4 per carat, but pieces that have a rich green color can sell for up to $30 a carat.
Tourmaline
Tourmaline is one of the most sought-after, and therefore most expensive, crystals available. Tourmaline can be black, pink, green, orange, blue, red, white, or a mix of colors. The rarest color is called Paraiba, which is a bright, almost neon blue or green with hints of orange or copper.
Common colors or stones that don’t have excellent clarity, depth, or coloration usually cost between $50 and $750 a carat, but rarer stones, particularly Paraiba tourmalines, can sell for $1,000 a carat and may even sell for up to $10,000 per carat.
Sunstone
Sunstone, which is a type of feldspar, is a gorgeous crystal with peach or pink hues. It can also have a deep red tone, similar to that of a ruby. Some sunstones also have blue, green, or purple tints. The price of a sunstone depends on the depth of color.
Stones that have only a hint of color are usually worth about $20 per carat, while stones with deeper colors can be worth up to $50 per carat.
Celestite
Celestite looks much like a geode in its raw form, and it’s usually a pale, smokey blue-gray color. It can also be pink, brown, light green, or clear. The stone can be polished and made into smooth stones or gems.
Celestite is usually sold in a cluster, and each cluster can range in price from $2 to $2,000, depending on the hue and the size of the cluster. Most celestite sells for between $10 and $20 per pound.
Sodalite
Sodalite is a dark blue mineral with colored veins running through it. It’s very common, so most sodalite is worth about $1 per carat.
Bismuth
Bismuth is a fascinating and beautiful crystal thanks to its array of gold, purple, green, and black tones as well as the way it forms an intricate square or rectangular structures.
Bismuth is usually sold by the pound, and it’s worth between $3 and $14 depending on the structure and color. Bismuth is usually found as a byproduct when mining metals like copper, tin, silver, and zinc.
Turquoise
Turquoise is often called a crystal by collectors, but it’s actually a cryptocrystalline mineral, and it almost never forms into single-crystal structures.
Most turquoise is worth between $1 and $10 per carat, although rarer, pure blue pieces can be worth up to $1,000 per carat, especially if they have few imperfections or other colors in them.
Obsidian
Like turquoise, obsidian is not a true crystal but is instead a congealed liquid made up of microscopic mineral crystals. Still, many crystal collectors consider it to be a crystal, and it’s supposed to offer power and protection. This shiny black stone can also help to ground people and keep them centered.
Obsidian usually costs between $2 and $100, depending on the size of the piece and whether or not it has been shaped in any way. The quality of the piece and how many flaws it has will also change its value.
