Eternity Ring Buying GuideEternity Ring Buying Guide



Eternity rings are a symbol of everlasting love and a commitment between two people. An eternity ring usually marks a significant milestone in a relationship, such as a special anniversary, a birthday or the birth of your first child. An eternity ring is a special gift that will be cherished for years to come- an eternity- so it’s important to choose the right design.

Eternity Ring Style


As eternity rings are a continuous band that has no beginning and no end, they have been seen as a symbol of eternal love for centuries. Rings given as a token of love are worn on the third finger of the left hand. This is a tradition believed to have had its beginnings in Roman Times. They believed that the ring finger contained the Vena Amoris- the Vein of Love- which was said to connect directly to the heart. Although now determined as a romantic myth, the tradition of wearing an eternity ring on this finger has continued into many modern cultures.

In modern times, the eternity ring is usually worn next to your engagement ring, with the wedding ring on the opposite side. However, there is no set rule of how the eternity ring is worn; some people like to wear their rings in the order they are received, whilst others like to wear the eternity ring on the right hand. It is entirely your decision how you want the rings to appear on your hand.



When looking for a diamond eternity ring, one of the main factors to consider is the diamond shape. While there is multi diamond shapes available, some diamond shapes are more popular to use in eternity ring than others.



The round cut diamond is the most popular diamond shape to be set within an eternity ring. As a round cut diamond has more facets than any other shape, this will ensure maximum sparkle and shine.



This square cut diamond sits beautiful in a channel set eternity ring, giving the appearance of an almost seamless band of diamonds dancing across the finger. The princess cut diamond gives the wearer a modern and sophisticated look.



Echoing back to old-Hollywood, the rectangular facets truly show off the diamond’s clarity.



The Oval Cut Diamond elongates the finger without losing its brilliance. A versatile and magnificent diamond choice!



If you’re looking for a diamond shape to optimise the carat weight, then the Marquise Cut is your diamond of choice.



An exceptional diamond cut, reminiscent of the Art-Deco era.




Claw Set





Full Rubover

Rub Over


A channel setting consists of two bands of metal encasing the diamonds within the band. This is considered a modern and classic look, perfect for princess cut diamonds and baguette cut diamonds.

It’s a secure and flush setting, allowing for a flush fit next to other rings and ensures there is no risk of snagging the ring during everyday wear.


Claw-set, also known as prong-set eternity rings, use small metal prongs to hold the diamonds within the band.

A claw setting is popular with round brilliant cut stones, as the diamonds will sit neatly next to each other and allow for optimum light to refract throughout the stones. A claw set eternity ring allows for the diamonds to be the focus of the band.


A pave-set eternity rings is reminiscent of vintage designs from the art deco era. Each diamond is individually claw set within the band, giving greater detail to this eternity ring design.


A bar set eternity ring is a unique design, perfect for someone to stand out from the crowd. Each diamond is held within a tension bar setting, letting in a great deal of light to showcase each diamond perfectly

Rub Over settings are the most secure you can select. While they don’t allow as much light to pass through the diamonds they give a high level of safety.






The type of coverage you select is an important decision to make.

You can choose from a full set eternity ring or a half set eternity ring. While a full eternity will mean you only ever see diamonds even as your ring rotates they are extremely difficult to re-size.

Haf eternity's can be resized relatively easily.


A full set eternity ring is continuous band of diamonds that has no beginning and no end, the original symbol of undying love.

A channel set full eternity ring is a modern and sleek design, which will sit flush against most engagement rings and wedding rings, whilst a prong full set eternity ring ensures as much light as possible is able to bounce throughout the diamonds.

The one flaw to having a full eternity ring however is that it cannot be resized, so it is imperative to ensure the correct ring size is chosen. Diamond Heaven however are happy to exchange for the correct size, should the initial size be incorrect.


A half diamond set eternity ring is a wonderful design choice, as it ensures all the diamonds are visible to the wearer.

The stones can graduate in size in a tapered band, or uniform in size with the band being the same width. The half diamond set also means that the ring can be altered in size in the future, should it be required.


A gemstone eternity ring is the perfect alternative to a diamond eternity ring. Adding a gemstone colour can give the eternity ring more of a story- it could be the birthstone to commemorate the birth of your first child, or maybe a ruby to celebrate your ruby anniversary. It gives you, the buyer, the opportunity to create a story of your own through your jewellery.

Blue sapphires are prized gemstones that are often used in jewellery and other ornamental objects. The intense hue of blue sapphires ranges from a deep blue-violet to a saturated blue green. For a sapphire to be classified as "blue," the body colour should not contain any hint of any other hue, such as green or purple.

Ultimately, the colour of a blue sapphire is determined by the presence of trace elements, such as iron and titanium, within its chemical structure. Most blue sapphires hail from India, Sri Lanka, Madagascar, and Thailand.


Ruby is a red gemstone that has been used in jewellery, deity statues, and other decorative pieces for centuries. It is the traditional gemstone of love and passion and is also believed to bring vitality and open the heart to compassion. Ruby is one of the four precious gemstones, along with diamond, sapphire, and emerald.

Rubies can be found in a variety of colours, ranging from deep red to pink and even purplish in hue. Usually, the brighter and deeper the colour, the more expensive the stone will be. There are also star rubies, which have an asterism, when viewed in direct light, as tiny needles of rutile can reflect star-like eight ray figures. Rubies are typically very hard and durable and have a hardness rating of 9 on the Mohs scale.


The emerald is a precious gemstone prized for its intense and radiant green colour. It ranges in colour from blue green to yellowish green and is believed to be one of the rarest and most valuable gemstones in the world. It is composed of a beryl variety of the mineral beryl and is rated 7.5 to 8.0 on the Mohs scale of mineral hardness.

Emeralds are usually found in the countries of Columbia, Zambia, Brazil, and Afghanistan and are widely used to create jewellery and decorative pieces. When cut and polished, it reveals subtle and unique shades of green. It is a symbol of rebirth and love and is said to bring luck and success to its wearer.


Black diamonds (also known as carbonado diamonds) are a type of diamond that is formed in conditions of incredibly high pressure and temperature. They possess an extremely dark tone which is greatly appreciated by the modern jewellery market.

Black diamonds are among the rarest and most opaque stones, with a hardness rating slightly lower than traditional white diamonds. They often have a brittle texture, with many fractures and inclusions, which give it a unique sparkle as light is reflected off the different surfaces. These special characteristics add to the allure of the stone, making it highly desirable among jewellers and gemstone enthusiasts.


The 4 C’s- Cut, Clarity, Colour and Carat- are all important elements to take into account when purchasing your diamond eternity ring. Here’s a brief recap on what each one means:


Carat refers to the weight of a diamond. Diamonds are all weighed in metric carats rather than grams or ounces. This is a standard industry practice around the world.

Diamond is expressed to the hundredth of a carat. Carat weight of less than a carat is expressed in points. So, for example, a 0.75ct diamond will be 75 points. Most jewellers will refer to carat weight in this terminology.

Another way to explain this would be using pounds, 100 pence equals 1 whole pound. Therefore 50pts will be 0.50ct and so on.

A common misconception is that it refers to the physical size of a diamond, which is incorrect. The diamond weight does not govern the size of stone.

We always recommend trying a range of carat weight on to determine which will be best for you. This way you will also be able to assess the visible size.


When searching for your perfect diamond, one of the C’s to consider during this process is the Colour.
Usually, people tend to choose a diamond with the least amount of colour, as it shows the purity of colour and rarity of quality.

The diamond colour grading system is based on an alphabetised system, starting from ‘D’, meaning the diamond is completely free of any colour, all the way to ‘Z’, meaning there is a visible tint of colour in the diamond.

To see a difference in colour between two diamonds, you usually have to compare at least three colour grades
(i.e, E Colour and a H Colour).


This will determine the number of natural inclusions that are inside the diamond. The higher the quality (such as VS1 or VVS1) will mean there are less inclusions, and the light is able to refract out of the diamond better than a lower clarity (such as SI2 or I1).

The way the diamond is cut will determine the sparkle and brilliance of the diamond. An excellent cut will reflect the optimum amount of light that enters the diamond. Lower quality cuts, such as good or poor, won’t reflect as much light and lack lustre.


The metal you choose should suit not only your partner’s style, but also showcase the diamond. Yellow Gold is a traditional choice and warming to most skin tones.


Platinum has become one of the most popular metals to be used in diamond eternity rings. Platinum is a naturally white coloured metal, meaning it will not tarnish and lose its brilliance. Platinum is also a very rare metal that is only mined in a few select areas of the world, making it a more expensive metal in comparison to Gold and Palladium.

Platinum will also enhance the colour of a diamond and its natural sparkle.

Platinum is usually hallmarked at ‘950’, meaning it is 95% pure platinum with the remaining 5% usually being palladium, iridium ruthenium and other alloys. Platinum is also a great choice for those who have contact allergies, as the purity of the platinum reduces the likelihood of any irritation during wear.

As with all metals, Platinum can scratch, however with proper care the wear should be minimal and can be polished again to return the metal to its original look.

18ct Rose Gold

This pink hue gold originally gained popularity in the 1920’s, then made a big comeback in the 2010’s. The unique blush tone of Rose Gold is created by mixing gold with copper. As all our gold eternity rings are 18kt gold, the composition will be 75% gold, with 25% copper. A Rose Gold diamond eternity ring gives an elegance that not all metals can achieve.

18ct White Gold

White Gold is still an incredibly popular choice of metal for diamond eternity ring settings. White Gold has the same overall appearance as Platinum, however it has a brighter ‘white shine’ and is less expensive than Platinum.

White gold is naturally an off-white colour, usually with a slight yellow tint. This is because white gold is usually mixed with palladium or magnesium.

To give white gold the trademark brightness, it is plated with rhodium or iridium. This plating will wear over time and return to its natural colour, however can be polishing and replated to return the metal to its former glory.

18ct Yellow Gold

Yellow Gold is a classic and timeless metal choice for any diamond eternity ring. For thousands of years, yellow gold has been used in jewellery for its warmth in colour and its resistance to erosion. The colour of the gold is determined by what other metal alloys are mixed with it, such as copper and zinc.
