How is your jewelry packaged?

Each piece is placed in a small transparent bag to protect it during shipment and avoid tangling. It is then placed in our premium suede Marcozo drawstring bag where you can store your pieces. All our products come with a black anti-tarnish tab to store with your jewelry, helping preserve the shine and extend the life of the plating. When it's ready for shipment, it's placed in a white bubble poly mailer and shipped to you! The reason we ship in a white bubble poly mailer is because it’s more discreet. We found that branded packaging drew attention and, unfortunately, led to stolen packages.

How do I find my ring size?

Getting the right ring size is important — especially when ordering online. Here's how to measure your ring size at home so you can order with confidence. Available Sizes Marcozo rings are available in whole sizes from 6 to 13. Half sizes are not available at this time. Method 1: Measure a Ring You Already Own 1. Find a ring that fits the finger you want to wear your new ring on. 2. Place the ring on a ruler and measure the inside diameter (the widest point across the inside of the ring) in millimeters. 3. Use the chart below to find your size. Ring Size Chart (Inside Diameter) Size 6 — 16.5 mm Size 7 — 17.3 mm Size 8 — 18.1 mm Size 9 — 19.0 mm Size 10 — 19.8 mm Size 11 — 20.6 mm Size 12 — 21.4 mm Size 13 — 22.2 mm Method 2: Measure Your Finger with String or Paper 1. Cut a thin strip of paper or a piece of string. 2. Wrap it snugly around the base of the finger you want to size (not too tight, not too loose). 3. Mark where the strip overlaps. 4. Lay it flat against a ruler and measure the length in millimeters — this is your circumference. 5. Use the chart below to find your size. Ring Size Chart (Circumference) Size 6 — 51.9 mm Size 7 — 54.4 mm Size 8 — 57.0 mm Size 9 — 59.5 mm Size 10 — 62.1 mm Size 11 — 64.6 mm Size 12 — 67.2 mm Size 13 — 69.7 mm Tips for an Accurate Measurement - Measure at the end of the day — fingers tend to swell slightly throughout the day, so evening measurements are the most accurate. - Avoid measuring when cold — cold temperatures can make your fingers shrink temporarily. - Measure multiple times — take 2–3 measurements to make sure you get a consistent result. - When in between sizes, go up — since we carry whole sizes only, we recommend sizing up if you're between two sizes. Ordered the Wrong Size? No worries! We offer exchanges within 14 days of delivery. Visit our returns page here: https://www.marcozo.com/pages/return-exchanges to get started.
