Jewelry Care Guide

Take care of your jewelry to keep it shining for years to come.

Everyday Care

• Avoid contact with water, perfumes, lotions, and sweat.
• Remove jewelry before exercising or showering.
• Store in a cool, dry place — ideally in a pouch or box.

Cleaning Tips

• Gently wipe with a soft, lint-free cloth after each wear.
• For light cleaning, soak briefly in lukewarm water with mild soap, then dry thoroughly.
• Avoid using harsh chemicals unless they are specifically made for jewelry.

What to Avoid

• Do not wear jewelry while swimming — chlorine and salt water can cause damage.
• Avoid prolonged exposure to direct sunlight, which may alter plating color.
• Don’t store multiple pieces together to prevent scratching.

Storage

• Store each piece separately in a soft pouch or lined jewelry box.
• Keep away from moisture and air exposure to prevent tarnishing.
• Use anti-tarnish strips if storing for extended periods.

How to Measure Your Ring Size at Home

Finding the perfect ring fit is easy with two simple methods: using a ring you already own or measuring with a string or paper strip.

1. Measure Using a Ring You Already Own

• Choose a ring that fits the intended finger perfectly
• Place the ring on a ruler or caliper and measure the inside diameter (in millimetres)
• Match the diameter to the Ring Size Chart on our website

Tip: Measure inner edge to inner edge, across the widest part of the ring — don’t include the band’s thickness.

2. Use a String or Paper Strip

• Cut a thin strip of paper or use a non-stretch string
• Wrap it around the base of your finger, snug but not tight
• Mark where the ends meet
• Measure the length in millimetres — this is your finger circumference
• Match it to the Inner Circumference column in our size chart

Tip: If you’re between two sizes, we recommend sizing up for a more comfortable fit.
