About the Stone
Diamond
Diamond is crystalline carbon. Natural diamonds form through geological processes; laboratory-grown diamonds are made in controlled conditions. Laboratory-grown diamonds are diamonds, while moissanite is a different material. Origin and identity are different questions, and a standard product photograph cannot reliably answer either.
Care: For routine cleaning, use a soft cloth and a gentle mild-soap hand clean when appropriate to the whole piece. Rinse and dry carefully. Avoid abrasive powders and harsh household chemicals. Leave ultrasonic and steam cleaning to a professional who has inspected the setting and checked treatment concerns. If a stone moves or a prong catches, have it checked before further wear.
