Among the finest of all crystal, our collection in made from the highest quality raw materials available resulting in absolutely clear and flawless crystal. Optical crystal is manufactured in large sheets then pressed under enormous pressure to ensure it has no bubbles or distortions. Our optical crystal awards are made from the same materials used in camera lenses, NASA telescopes and high-end visual equipment. Unlike Lead Crystal, optical crystal is lead free which is perfect for all kinds of engraving methods though we choose to sand blast, which provides the highest quality etch. Each piece is hand polished and beveled to perfection to achieve a mystical refraction. Clear, black, blue, pink, green and amber accents are also used in our Optical Crystal Awards and Gifts collection for a more contemporary design.
