The process of cleaning the emerald and cutting the amethyst necklace is actually the art of playing with time. When the maintenance program is accurate to the nanoscale control, when the maintenance cycle is dynamically optimized by big data, the life of the jewelry can break through the physical limitations. As designers, we create not only static beauty, but also a set of sustainable survival ecosystem – this may be the real eternal contract between jewelry and the wearer.
Material characteristics and risk matrix
Accurate maintenance needs to establish a risk control model based on scientific understanding of material characteristics.

Conclusion
To properly clean and maintain an emerald-cut amethyst necklace, use mild soap, warm water, and a soft brush to gently scrub the stone. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaning, as they can damage the amethyst. Rinse thoroughly and dry with a lint-free cloth. Store it separately in a soft pouch to prevent scratches. Keep it away from prolonged sunlight and heat to prevent color fading. Regularly inspect the setting for loose prongs or damage. Professional cleaning and checks every 6–12 months are recommended. Handle with care to preserve its beauty and longevity.
