It should not have unreported internal flaws or inclusions that are visible with a 10-power loop either.Ī crystal or cluster should not have damage you can see with your naked eye. If you are buying a gemstone, it should not have external damage that is visible with a 10-power loupe. However, as the buyer, you have to do the final inspection. Reputable dealers will point out nicks and abrasions, and will fully disclose damage and repair. Ensure you look carefully and inspect any crystal or cluster. Of course, mining, cleaning, packaging, and transporting also are hazardous. Since most crystals grow in the ground, they are subject to many kinds of damage. Again, like many things, damage reduces value. You are concerned with both the external of the crystal and its insides. The second factor in the value of a crystal is its condition. The second line says 5 carats is one gram and 1/28 of an ounce. For example the first line says 1 carat is 1/5 of a gram and is 1/141 of an ounce. It is twice as big, but costs over three times as much.Ĭrystals, Gemstones and crystal clusters are often sold by weight. If the second, bigger one weighed 20 grams it would be $100. If the first one weighed 10 grams it would cost $30.
For example a small topaz crystal might cost $3 per gram.
Like many things, the larger the crystal the more it will cost PER UNIT OF WEIGHT. The first factor is the size of the crystal or cluster.
Each of these factors should be considered when you are deciding to purchase a crystal or gemstone. The value of a crystal is dependant on several factors. Buying crystals either as a single crystal, a gemstone, or a cluster involves determining the value and comparing it to the offered price.
