3201-30 Swarovski Hanging Crystal Octogon Shape size = Height 30mm Width 30mm. Hang in the window as sun catchers, as the sun shines on them you will get rainbow colours round the room. Made from Optical Crystal. Our machine cut crystal is manufactured in Austria. After diamonds and other precious stones, crystal is the most suitable material to split light so that it shines. Crystal has no flaws, such as streaks or bubbles, and is therefore clearer than air and water. This high quality is achieved by the use of carefully selected raw materials and ingenious manufacturing processes. Light is made up of different colours and diffuses into waves. A transparent medium like crystal means that light can be classified by the colours of the spectrum due to the way in which it passes through crystal at different speeds. The brilliance, sparkle and shimmer are produced by the reflection of white light. Purity and precision cutting are prerequisites for the brightness and play of colours in crystal. When light penetrates a transparent medium it decelerates and refracts. The term used is "splitting". Depending on the location of the facets, the light follows defined routes and is then dispersed into a colour spectrum. Heated in the furnace, it melts and turns into a viscous fluid. It is then worked into a semi-finished piece with the shape of the final product. The glass bends to the new destiny. It then cools and hardens. The engineers use computer-controlled cutting machines that can create precise facets on even the smallest crystal. In many separate production steps, the facets are ground and their edges cut until the incoming light can break into the spectral colours. Crystal polishing ensures a perfect finish for each crystal component. Thanks to an innovative finishing technique, the surface is so smooth that dust and water rarely collect on it. This guarantees a clear, faultless sparkle. Each individual crystal is controlled to the highest degree of precision by trained hands and keen eyes.
