Emerald Eternity Ring - Portofino
Necklaces
This is how you'll know exactly where the necklace will rest on your body.
General Tip: The standard length for women is usually 42-45 cm, and for men 50-55 cm.
-
Method 1: Measuring with a String (Custom Fit)
Want the perfect length? Take a string (any length), place it around your neck in front of a mirror, and hold it at the point that looks most flattering and suitable for your look. Mark this point (where the string ends), then lay the string on a ruler to find out the exact length in cm. -
Method 2: Measuring a Favorite Necklace
Do you have a necklace that's the perfect length? Lay it open and straight on a flat surface and measure it from end to end with a ruler. If you're unsure, remember that thicker necklaces usually sit slightly higher than thinner necklaces of the same length.
Bracelets
A guide to finding the perfect balance between comfort and style.
Average Sizes: The average wrist circumference for women is 15-17 cm, and for men 18-21 cm.
-
Method 1: Measuring Wrist Circumference
Measure the circumference of your wrist snugly around the prominent bone using a measuring tape. To the result, add an allowance for comfort: 1 cm for a close fit or 2 cm for a loose fit. The total sum is the size to order. -
Method 2: Measuring an Existing Bracelet
Do you have a bracelet that fits you perfectly? Lay it open and straight on a ruler and measure it from end to end (including the clasp). The length you get in cm is the exact size.
Rings
Two simple ways to find the exact size, so the ring fits you perfectly.
-
Method 1: Measuring with a Flexible Tape
Don't have a ring that fits your hand? Wrap your finger with a measuring tape (or a strip of paper) comfortably but snugly. Mark the meeting point and check the length in millimeters against the size chart on the website. -
Method 2: Measuring an Existing Ring (The Quick Method)
Take a ring that fits you well, place it on a ruler and measure only the inner diameter (the empty space, without the walls). Compare the result to our chart.
Earrings
Two simple and accurate ways to find your size from home, to choose the exact presence you're looking for.
-
Method 1: Carat Check and Accurate Calculation
Place the earring on a ruler and measure the diameter of the diamond in mm. Instead of relying on a general chart, ask Google or AI: "How many carats does a diamond with a diameter of [your measurement] mm weigh?" to get the most accurate answer. Want a specific size? Specify it in the order notes and we will custom-make the earring for you. -
Method 2: Size Comparison and Ear Visualization
A close-up photo can be misleading. To help you understand the true proportions, we've created a visualization showing different diamond sizes (from 0.25 to 3 carats) on the same ear. This way, you can choose whether you're looking for a delicate and minimalist look or a prominent and luxurious one.
Order with Peace of Mind
It's important to us that the jewelry feels like it was made especially for you.
If, after measuring at home, you feel a slight adjustment is needed, we'd be happy to perform the first size adjustment for free. You only pay for shipping, and we'll take care of the rest.
