Manganese Dendrites come in all shapes and sizes.
From a few grams weight to several hundred kilograms.
Weight is very easy to describe.
However the Dimensions of a Manganese Dendrite can be much more difficult to describe.
Triangular, 4 sided pyramid, box, irregular, 2 sided flat, 3 sided pyramid, and the list goes on.
The best way to describe or show the dimensions of a dendrite is with a video. Hold it in your hand (or both hands if it’s big) and turn it slowly around. A turntable works for many dendrites as well. Natural sunlight is the best light for shooting a video.
To list the physical dimensions, like 3cm X 5cm X 1cm, you should list the Main Feature side first.
For a photograph, you should have at least 4 or 5 pictures from different sides, and either a hand holding it or an object next to it to reference size. A U.S… dollar, a lighter, or some other universal object that is the same size around the world.
