Robert Clerc Synthetic Alexandrite Ring

• Alexandrite - Alexandrite is a variety of the mineral chrysoberyl that is prized for its unique ability to appear to change colour under different lighting conditions. It is a highly sought-after gemstone and is often used in fine jewellery. In natural light, alexandrite appears to be a shade of green, but when viewed under incandescent light, it appears to be a shade of red. This property, known as the alexandrite effect, is caused by the presence of trace amounts of chromium in the crystal structure of the gemstone. The colour change is due to the way that the gemstone absorbs and reflects light. Alexandrite is a relatively hard gemstone and is suitable for use in all types of jewellery, including rings, earrings, pendants, and bracelets. It is often used as a centre stone in engagement rings, due to its rarity and beauty. It is also used in other types of fine jewellery, such as brooches, necklaces, and cufflinks. The gemstone is typically cut into oval, pear, or cushion shapes and is usually set in gold or platinum.
• Bezel - On a clock or watch, the bezel is the metal frame into which the watch or clock glass is fitted. In clocks, the bezel may include a hinge and a flange, in effect a door to the face of the clock. In jewellery the bezel is a band of metal with a projecting lip that holds the gemstone in its setting.
