Understanding Gemstone Properties

Before cleaning your gemstone jewelry, it’s crucial to understand the properties of each gemstone. Different gems can react differently to heat, light, acids, and scratching. The physical properties of gemstones play a significant role in determining the appropriate cleaning methods and precautions.

Hardness is an important property to consider, but it doesn’t necessarily indicate resistance to all types of exposure. For example, diamonds, being the hardest natural material, can still have inclusions or cleaves that might react to heat or mechanical cleaning. Therefore, it’s important to handle diamonds with care and use appropriate cleaning techniques.

Gem treatments and enhancements should also be taken into account. Certain gemstones undergo treatments to improve their appearance or durability, such as filling fractures or adding oils to enhance transparency. These treatments can impact the cleaning process, and it’s crucial to be aware of any treatments or enhancements your gemstones may have undergone before cleaning them.

Rinse with clean water and pat dry with a soft lint-free cloth.

3. Store and handle with care:

Soft porous gemstones are susceptible to scratches and damage from other harder materials. Store them separately from other jewelry items in a soft pouch or a lined jewelry box to minimize contact and prevent scratching.
