This applies to any of our sites which sell Crystals. Gemstones are natural material, and so it is impossible to get any uniformity of size and shape. Because crystals vary so there is no perfect way to classify them exactly. We do however, grade them roughly into size ranges according to the following guidelines:
|
| Small: Approx 10-15mm |
 |
| Med: Approx 15-25mm |
| Large: Approx 25-30mm |
| Jumbo: Approx 30-35+mm |
|
Each crystal type has its own particular hardness and this can affect the results of the tumbling and polishing process. It is inevitable you will find the odd small blemish or other small flaws in most crystals. This is perfectly normal and does not affect either the aesthetic or metaphysical properties of a crystal.
