Know Your Jewellery Size and Measurements

Once you have decided the type of jewellery you want, it's time to choose your jewellery size and measurements.

Ring Size and Finger Measurements

Getting a ring that fits perfectly is one of the most important things to keep in mind when buying one. You don't want it too loose or too tight! That's why it's critical to know your ring size before you go shopping.

Here’s how you can find your perfect ring size:

To measure your finger:

Wrap a string around your finger, but make sure it's not too tight.
Place the string on a ruler with millimetres (mm) and take note of the measurement of the length of string used.
Use the chart to find the ideal ring size. If you see this icon, this means the ring size cannot be resized.

Chain Types and Measurements

The type of chain can make or break a piece. The wrong chain can look out-of-place, or even weigh down the rest of your design. But the right chain can be an elegant, minimalistic addition that really pulls the whole item together.

When it comes to choosing a chain, there are three basic factors to keep in mind:

The main purpose of the chain: Do you want it to be a decorative element or to serve as a setting for your favourite pendant?
The weight of the chain: How thick or heavy do you want the chain to be
The material of the chain: What type of precious metal are you looking for?

Once you have the answers to these questions in mind, you can proceed to find the perfect type of chain. Here are some types and lengths of chains to consider!

Types of chains

Cable Chains

Cable chains, with their uniform round or oval links connected at 90 degrees forma classic jewellery chain. They are a traditional choice because they are beautiful, versatile, and easy to wear.

Rolo Chains

Designed with symmetrical round or oval links, Rolo chains are typically thicker than a standard cable chain and are often flat on the inside. They're an excellent choice for pendants that have a lot of detail.

Wheat Chains

Wheat chains have oval and twist oval links intertwined to form an intricate chain with a braided profile. These chains have a beautiful, almost floral look that makes them especially popular for springtime fashion.

Snake Chains

A smooth, tightly linked chain with a round or square cross-section and a slight zig zag effect form the aesthetic factor of a snake chain. They are elegant and eye-catching and are particularly ideal for anyone who likes wearing long necklaces.

Necklace (Chains) Length

Chains come in a variety of lengths, but how do you know what length suits you best? Lucky for you, we've got a handy guide for that!

When it comes to necklace length, there are six general categories.

Choker length: A choker-length chain fits tightly around the neck. This length is usually between 13 and 15 inches.
Collar length: A collar-length chain sits comfortably at the base of the neck. This length is usually between 16 and 17 inches.
Princess length: Princess-length chains are one of the most common necklace lengths around, and they sit on the collarbone. These chains are usually between 17 and 19 inches long.
Matinee length: Matinee-length chains sit somewhere between the collarbone and the bustline, usually between 20 and 24 inches long.
Opera-length: Opera-length chains sit from the top of the bust to just below for around 28-37 inches.
Rope-length: Rope-length chains sit at the waistline or below, or more than 37 inches long.

Additional Tips for Buying Diamonds and Gemstones

Here are a few additional tips to make your pre-owned diamond and gemstone jewellery buying process more effortless and rewarding!

Check certifications. Certificates provide proof that the diamond or gemstone you are buying is authentic and conflict-free.
We suggest that you buy diamond jewellery from verified sellers.
Pay special attention to the condition of the item you are looking forward buy. Since GEMGEM is a reselling marketplace, each and every piece of jewellery listed on the platform is pre-owned. Hence it is particularly important to check the year of purchase and the exact condition of the piece, for example whether it is almost-new, rarely worn, heavily worn, and so on.
Make sure that you have gone through every available resource to get a better idea of the jewellery you are buying. Check out the item description and all available photos and videos uploaded by the seller thoroughly.
