TWO BA­SIC SHAPES:

DA MAN - Caliber - - NEWS -

FLAT

While this shape is the most widely used in the mar­ket, flat crys­tals are sus­cep­ti­ble to shat­ter­ing or crack­ing. If used un­der­wa­ter, the flat shape might be­come re­flec­tive when seen at cer­tain an­gles or if no coat­ing is ap­plied on the crys­tal.

DOMED

A domed shape dis­trib­utes any force ap­plied to it evenly around the crys­tal and is there­fore more re­sis­tant to shat­ter­ing and crack­ing. How­ever, the higher the cur­va­ture, the higher the risk of dam­age and abra­sion.
