Ring Sizing FAQ

How do I find my ring size at home?
You can estimate your ring size at home by wrapping a thin strip of paper or string around your finger, marking where it meets, and measuring the length in millimeters. That measurement can then be compared against the Icebox ring size chart to find the closest match. For the most reliable result, measure more than once and avoid sizing when your hands are especially cold or swollen.
Can I use a ring I already own to find my size?
Yes. One of the easiest ways to find your ring size is by measuring the interior diameter of a ring that already fits the intended finger well. Once you have that measurement in millimeters, you can compare it to the Icebox chart to identify the closest US ring size. This is often the best method when shopping for yourself and comparing against a ring you already wear comfortably.
What if I am between two ring sizes?
If you fall between two sizes, the better choice often depends on the ring style and how you prefer it to fit. Wider bands can feel tighter, while slimmer bands may feel slightly looser. In many cases, choosing the slightly larger size is the safer option, especially if your fingers tend to swell throughout the day. If you are unsure, the Icebox team can help guide you before you place your order.
Do ring sizes fit the same across every style?
Not always. The fit of a ring can vary depending on the band width, interior shape, design, and overall weight of the piece. A slim ring and a wide statement ring may feel different even in the same numeric size. That is why using the size chart as a guide is important, while also considering the style you are purchasing.
Does Icebox offer ring resizing?
Yes. Icebox offers complimentary resizing within 30 days of purchase on eligible rings. In most cases, rings can be adjusted up or down by two sizes from the original size. Some styles, including certain eternity rings, cannot be resized. If you are purchasing a ring and are unsure about the fit, our team can help you understand what options may be available.
What should I do if I am unsure which ring size to order?
If you are unsure, contact the Icebox concierge before placing your order. Our team can help you review the size chart, compare measurements, and make the most informed choice based on the ring style you are considering. It is always better to confirm fit before ordering, especially for fine jewelry and engagement pieces.

Chain & Necklace Sizing FAQ

How do I choose the right chain or necklace length?
The right chain or necklace length depends on how you want the piece to sit, the size of the pendant if applicable, and your personal styling preference. You can use the Icebox necklace size guide to compare common lengths and visualize how each may wear. Some clients prefer a close fit at the collar, while others want a lower, more relaxed drop.
How can I measure necklace length at home?
A simple way to measure at home is to wrap a string or flexible tape around your neck to the exact point where you want the necklace to fall, then measure that length in inches. Once you have the number, compare it to the Icebox chart to find the closest standard size. This is a useful way to understand how a chain will sit before placing your order.
Can I use a necklace I already own as a reference?
Yes. Take a necklace that fits the way you like, lay it flat, measure it from end to end, and compare that measurement to the listed size. If you are measuring only one side while folded in half, multiply by two to get the full length. This is one of the easiest ways to shop confidently when ordering chains or necklaces online.
What necklace lengths are most common?
Some of the most common necklace lengths are 16", 18", 20", 22", and 24", though the best choice depends on the piece and how you want it styled. Shorter lengths sit higher and feel more fitted, while longer lengths create a lower, more statement-driven look. The Icebox size guide helps you compare those lengths before deciding.
Does pendant size affect which chain length I should choose?
Yes. The size, weight, and visual scale of a pendant can affect how a chain wears and how balanced the final look feels. Larger pendants often pair better with slightly longer or more substantial chains, while smaller pendants may work well with shorter lengths. If you are pairing a chain with a specific pendant, it is worth considering both together before ordering.
What if I am not sure which chain or necklace length to order?
If you are unsure, contact the Icebox concierge for help before placing your order. Our team can help you think through styling, layering, pendant pairing, and the overall fit you are looking for. A quick check before purchase can make choosing the right length much easier.

Bracelet Sizing FAQ

How do I find the right bracelet size?
The right bracelet size starts with measuring your wrist and deciding how close or relaxed you want the fit to feel. You can use the Icebox bracelet size guide to compare standard lengths and choose the option that best matches your measurement. Some clients prefer a closer fit, while others want more movement and a slightly looser feel.
How can I measure my wrist at home?
Wrap a flexible tape, string, or strip of paper around your wrist where you would normally wear the bracelet, mark the point where it meets, and measure the length. Then compare that number to the Icebox bracelet chart to find the closest size. Measuring more than once is a good way to make sure the result is accurate.
Can I use a bracelet I already own to figure out my size?
Yes. Using a bracelet you already wear comfortably is one of the easiest ways to estimate the right fit. Measure the inside length or interior diameter depending on the style, then compare it to the Icebox size guide. This method is especially helpful when buying a similar bracelet style online.
What should I do if I am between bracelet sizes?
If you are between sizes, the better option depends on the bracelet style and how you like it to fit. Some clients prefer a more fitted look, while others want additional room for comfort and movement. In many cases, sizing slightly up is the safer choice, especially for more structured bracelet styles.
Do different bracelet styles fit differently?
Yes. The fit can vary based on the bracelet’s width, construction, clasp type, and overall rigidity. A flexible bracelet may wear differently than a more structured or solid design, even at the same listed size. That is why it is helpful to use the size guide alongside the specific style you are considering.
What if I am unsure which bracelet size to order?
If you are unsure, contact the Icebox concierge before ordering. Our team can help you review your wrist measurement, compare sizes, and choose the option that makes the most sense for the bracelet you want. That extra guidance can help you buy more confidently and avoid guessing.
