Frequently Asked Questions

Diamond necklaces are versatile with a range of designs available. From the more subtle and simple to the more eye-catching and extravagant. Here is a summary of some of the most popular types of diamond necklaces.


Solitaire pendants feature a single diamond, this is reflected in the name which derives from the Latin word 'solitarius' which means 'isolated' similar to a solitaire ring. The single stone is suspended from a chain emphasising the quality, cut and clarity. It is worn close to the heart symbolising enduring love both platonic and romantic.


Statement necklaces are bold and grab attention. This can be through it being a large piece, the use of different materials, colours or intriguing design elements. They are effectively the opposite to delicate or dainty necklaces.


Diamond chokers are close fitting and don't hang down. Sometimes they may have pendants in the centre. Diamond chockers are embellished with the gemstone.


Layered diamond necklaces is the style of wearing multiple necklaces at once. Usually, the necklaces will vary in length and style.

Finding the right necklace length can help to find what will be most flattering for you and the occasion.


Short (chokers and collars). Collar necklaces sit at the base of the throat at 12 – 14 inches long. Chokers are less tight and lie slightly below a collar necklace at 14 – 16 inches long. Both look especially good with strapless, off the shoulder or sweetheart necklines. Avoid this style if you're wearing a turtle neck or a low-cut neckline as it can elongate your chest. Chokers tend to suit if you are petite as longer necklaces can hang too low. Choker and collar necklaces are close fitting and work great for smoothing out the angles on heart shaped faces.

Long (opera and rope). Opera and rope necklaces are the longer style. Opera necklaces fall lower than a matinee necklace measuring from 28 – 32 inches but work with similar necklines. The longest is the rope necklace measuring 32 inches or more, almost reaching your waist. It can be worn as it is or can be made shorter in length wrapping a couple times. Longer drop necklaces work with turtle necks or open necklines like a scoop V-neck. Longer necklaces with a charm or pendant suit oval shaped faces and can create a slimming v shape. For taller people a longer necklace can complement the length of your torso.

For an elegant yet effortless everyday look, opt for a simple diamond pendant, such as a solitaire, paired with a V-neck jumper or a slim-fitting shirt. Keep clothing minimal to let the necklace stand out. You can also try layering delicate chains around 2 inches apart for a casual chic vibe. Mixing metals, chain styles, or gemstone accents can add extra flair, while keeping the diamond the focal point.

In work environments, choose minimalist diamond necklaces, like a small solitaire on a fine chain. Layered necklaces with subtle differences in length create a refined look without being overly bold. A diamond pendant can enhance a monochrome or tailored outfit, striking the perfect balance between polish and professionalism.

For formal occasions, statement diamond necklaces pair beautifully with gowns, especially those with V-necks, scoop necks, or off-the-shoulder cuts. A choker works well with strapless dresses, while a larger necklace suits plunging necklines. If the necklace is your focal point, keep earrings subtle and wear a simple bracelet. If you prefer bold earrings like hoops, consider skipping the necklace or choosing a more delicate chain.

To create a well-styled layered look, start with your favourite chain length and build around it. Keep approximately 2 inches between each layer for balance. Mix textures, chain thicknesses, metals, or gemstone accents to add personality while keeping the overall look cohesive.
