Unfortunately, I don’t have access to specific product information, including dimensions.

To find the dimensions of a specific piece of jewelry :

1. Check the product page : Most online retailers and jewelry websites will list the dimensions of the piece on the product page. Look for details like:
Length : For necklaces, bracelets, and earrings.
Width : For rings, bracelets, and pendants.
Height : For pendants, earrings, and some rings.
Stone size : If the piece features gemstones.

2. Contact the seller : If you can’t find the dimensions on the product page, you can contact the seller directly. They should be able to provide you with the specific measurements.

Gentle Cleaning : For most jewelry, a simple solution of warm water and mild dish soap is sufficient. Soak the jewelry for a few minutes, then gently scrub with a soft toothbrush. Rinse thoroughly with clean water and pat dry with a soft cloth.  
Avoid Harsh Chemicals : Never use abrasive cleaners, bleach, or ammonia, as these can damage the metal and gemstones.  
Professional Cleaning : For delicate or intricate pieces, or if you’re unsure about cleaning methods, it’s best to take your jewelry to a professional jeweler for cleaning.

Separate Storage : Store your jewelry pieces separately to prevent them from scratching or tangling. Use small plastic bags or jewelry boxes with compartments.  
Avoid Extreme Conditions : Keep your jewelry away from direct sunlight, heat, and humidity. These conditions can cause discoloration and damage.
