We use only high-quality materials to ensure that your new jewelry will accompany you for many years. Here are a few useful tips on how to care for your jewelry, preserving its beauty, shine and durability. 

- Avoid using water or chemicals to clean your jewelry. Instead, use a soft, nonabrasive cloth with a drop of natural oil.
- Wear your sterling silver jewelry regularly. If not worn for a long time, silver can tarnish. If tarnishing is very severe, you can rub the piece with a drop of dish soap or nonabrasive toothpaste and then rinse with water
- Avoid direct contact with perfumes, lotions or any chemical cosmetics.
- Remove jewelry before bathing, swimming, saunas or sulfur baths. Avoid contact with chlorine, sand and salt water to prevent tarnishing.
- Remove jewelry before doing any exercise and before sleeping to avoid accidental damage.
- Store the jewelry away from any exposure to sunlight or extreme temperatures, ideally in a padded jewelry box or tarnish-resistant bag. You can also keep these in individual airtight plastic (polyethylene) bags. Avoid keeping it in a bathroom or any humid locations!
- Avoid packing two pieces of jewelry together as it can cause scratches and damage. 

If you think your gold plated jewelry needs a refresh, please contact us so we can re-plate it. We offer re-plating at a fair price. 

- You can keep your jewelry for showering and bathing.
- To clean the jewelry, use a soft, non-abrasive cloth with a drop of dish soap and rinse with water. 

If the surface changes over time, we will be happy to re-polish your jewelry and  make it shinier or more matt to restore it to its original finish.

Are you unsure about your ring size? Let us help you find it using the chart above and three different methods.

Take an existing ring that fits you perfectly, place it on a horizontal surface and measure its inside diameter with a ruler. Once you have the measurement, refer to the "INSIDE DIAMETER" column of the chart above and find the corresponding "LMJ SIZE."  Keep in mind that the ring size can vary by about half a size depending on temperature, hydration levels, hormones, etc. In case you are between two sizes, we recommend choosing  the largest one. 

If you do not have a ring of the desired size, you need to measure the diameter of your finger. To do this, cut a thin strip of paper and wrap it around the base of your finger like a ring. Mark the paper at the point where it completes a circle. Use a ruler to measure the length of the strip of paper to the mark made. Refer to the "FINGER CIRCUMFERENCE" column in the chart above to find the corresponding LMJ size. 

If you know your size in the UK or EU sizing, refer to the "EU SIZE" or "UK SIZE" columns in the chart above to find the corresponding LMJ size. You can also use this website to find other classification tables.
