Buying the Right Size Ring

Buying the right size mens rings over the internet is actually simpler than it may first seem and we hope that this help page along with our 14 day returns policy gives you the necessary information and confidence to make a purchase  with us.

There are several ways to accurately measure your finger and several other tips to be aware of to ensure you purchase the right size ring:

Purchasing Tips

1. Some of the rings we stock on this website are described as “wide”. For such rings we suggest that you purchase 1 UK size bigger than your actual finger size for a comfortable fit.
2. Other rings on our website are described as “slightly tapered”. These are specifically designed for comfort and are sized at the narrowest point so you should order your actual finger size even if they are also described as “wide”.

Measuring your Finger or an Existing Ring

1. The first thing to be aware of is that your fingers change size with different temperatures, at different times of day and even humidity. For the best fit, we suggest that you measure at room temperature (not after showering, being outdoors in the winter, vigorous exercise, etc.) and toward the end of the day (when the fingers are typically largest).
2. If the finger joints are prominent, we recommend that you measure the widest part of the finger for a tight fitting ring.
3. If the measurement is between two potential sizes, choose the larger size to be sure it will fit
4. The best place to have your fingers measured is in your local high street jewellers, but often if you are buying for somebody else, particularly if it’s a surprise, this is not always possible even if your were buying a ring on the high street.
5. Alternatively, you can register on our website and e-mail us at This e-mail address is being protected from spambots. You need JavaScript enabled to view it   to request a free sizing guide along with your mailing details. We will be happy to send you the sizing guide in the first class mail, so it would be with you as early as the next working day. We will also post you simple instructions on how to use the sizing guide to either compare with an existing ring or to measure your finger accurately.
6. Some sites offer a print out of a sizing guide, however because these are typically printed on paper and not stiff card we regard these as inaccurate and advise you not to use them.

Sizes Not Currently in Stock

All our mens jewellery items are described as either “in stock” or “this product is currently not available” in the product details pages on the website and we aim to stock a minimum of 3 sizes of all rings at all times, so that we can at least offer small, medium and large options to our customers.

While we may have a ring in stock, you may find that we do not have the exact size you wish to purchase, in which case we suggest that you contact us by email or phone 01844-342500 to find out how long it will take to obtain the size you require. As an indication, it normally takes us less than 10 days restock from our suppliers and it’s quite possible that we are already in the process of restocking when you call and the time for delivery to you may be much shorter.

Some of our suppliers only manufacture 3 sizes of ring (small, medium and large) and other sizes are simply not available. In these circumstances, is advisable to purchase a different ring, or choose the closest ring size to your measured finger and return it to us within 7 days of purchase if it does not fit.

Size Conversion

All our rings which are currently in stock are listed on the website in both UK sizing (A-Z) and in EU sizing (mm of internal circumference). To convert these to international sizes please use the following table:

Caring for your Jewellery

Wear & Care, not Wear and Tear

With wear and tear, enamel may crack, diamonds may chip, chain links may snap and the highly polished surfaces of precious metals used in men's jewellery may scratch, so we recommend the following precautions and care for your jewellery, so that wearing it becomes as bright and fulfilling as the day it was new.


A popular misconception is that diamonds cannot be chipped or broken, but sadly that is not true. The hardest of all natural minerals, diamonds are almost completely scratch proof, but that doesn't stop them chipping or cracking when hit. It's therefore a sensible precaution to remove diamond rings and other mens jewellery during sports activities, manual work as a sharp impact may result in the diamond breaking.

Platinum and Gold are very hardy metals able to uphold to the rigours of normal daily use, however even with careful wear will inevitably become tarnished with small scratches to the surface and tiny dents. With hard wear the jewellery may even misshapen. We recommend polishing with a soft cloth but it is not recommended to use a silver polishing cloth as they are generally impregnated with abrasive powder.


Pure Silver metal is too soft for making jewellery, therefore sterling silver 925 is mostly used. Sterling Silver is an alloy of 92.5% pure silver and 7.5% other metals and due to the presence of the base metals, may oxidise over time and become blackened, especially as they come into regular contact with natural acids in your skin.

The oxidised blackening normally stops of its own accord after a while and then with continued wear the oxidised layer will gradually wear off itself. In the meantime you can polish it with a silver polish cloth (available from Thorn Jewellery on request) and or use a silver dip solution. If it still continues to oxidise, a technique is to rhodium plate or pure silver-plate the item.

Special finishes

Matt finishes are temporary and produced by scratching or pitting the surface of a metal in a uniform way, and whether they start polished or matt, with normal wear men's rings will end up looking the same after several months. Items can be re-finished to bring them back to life, so please contact Thorn Jewellery for more information.

Rhodium, Gold, Platinum and Pure Silver plated finishes are created by a process of bonding a micron layer of the precious metal to a surface. All of these types of plating are susceptible to wear and tear and replating is an effective method of returning the item to its former beauty.

Cleaning of stone set jewellery

Your diamond and other hard stone jewellery should be soaked in hot soapy water for ten minutes and then cleaned with a soft toothbrush under warm running water. However, this is not the case with pearls, or any other porous stones, such as opal, lapis etc. These should instead be cleaned with a soft cloth and regularly re-oiled using natural oil. It is also advised that this group of gems are not left in strong sunlight for long periods of time as this can lead to drying out and cracking.


Cufflink Backs Guide

Swivel Back Cufflinks

Of all the cufflinks back styles the swivel back (toggle) is currently the most popular, as it is easy to fasten and holds the cuff tight. The swivel back cufflinks feature a designed front plate with a rigid fixed bar soldered to the back. This rigid bar is pushed through the double-cuff of a dress shirt and at the opposite end of the fixed piece is a moving "swivel" bar which twists to right angles to secure the cuff.

Chain Cufflink Backs

The traditional chain cufflink has front and back plates, often of similar sizes with a short chain that connecting front with back. The thin back plate it pushed through the double-cuff of a dress shirt and holds the cuff secure similarly to a standard button. This style of cufflink is often personalised with engraved initials on the cufflinks back plate. Thorn Jewellery do offer an engraving service if it is required for any of our purchased items.

Fixed Cufflink Backs

The fixed or stationary cufflink has a solid fixed back which is an integral part of the design of the cufflink and which is often engraved, enamelled or cast as well. It is secured by pushing through a tight buttonhole and rotating.


Glossary of Terms used by Thorn to Descibe Mens Jewellery


Carat (ct)
Carat is a unit of weight for precious stones. It is important not to confuse this with ‘karat’, which is a measure of the purity of gold. ‘Carat’ is abbreviated to "ct." One carat is equal to 1/5 of a gram (200 milligrams). Stones are measured to the nearest hundredth of a carat. There are a hundred points in a carat, so that a .10 carat stone can also be described as a 10 point stone.

refers to diamond shape and/or quality of cut

Enamel is produced by fusing coloured powdered glass ‘paste’ to metal to produce a glass-like, decorative surface. The colour of the enamel and its transparency depend on the metal oxides in the glass and the temperature at which the glass melts and coheres to the surface. In some cases, the enamel may be translucent with fancy engraving on the metal underneath, which produces guilloche enamel.

This is gouging out a design in metal with graver's tools, or embellishing metal or other material with patterns using a stamping tool or drill. This was fashionable in mid-Victorian jewellery. The resulting depressions were often filled with coloured enamel.

Gold Purity
Gold Purity is expressed in karats ('K'). Gold is alloyed with other metals such as silver, copper, zinc, or silicon to produce varying colours and purities less than 24 carat. Typically the finest gold used in jewellery is 18K (75% pure).

This is a stamped mark applied to items of jewellery and silverware by the Assay Offices of Britain as a guarantee of authenticity. The mark consists of four components: The sponsor (or manufacturer) mark; the standard mark, which denotes the precious metal content of the item; the Assay Office Mark (Assay Offices are found in London, Birmingham, Sheffield and Edinburgh) and the date letter which shows the year in which the article was hallmarked.

An Inlay is when a space is formed or routed out of the metal and a contrasting material is fitted into the created space.  The Stephen Webster Sex Drugs and Rock n Roll Ring with Onyx Inlay is a fine example of this technique in craftmanship.

Karat is a measure of the purity of gold. The ratio of gold to other metals is measured in 24 parts, called ‘karats’.  Hence pure gold is 24 karat gold, while 18 karat gold used in Jewellery making is 18 parts gold and 6 parts other metals.

Pave is a multiple small set of gemstones as closely together as possible in two or more rows

Sterling Silver (925)
The Sterling Silver standard used extensively in mens jewellery has a minimum millesimal fineness of 925. Meaning that Sterling silver is an alloy containing 92.5% Silver and no more than 7.5% other metals.


What are colour treated diamonds?

Used extensively by Jess Canty in the Idol Collection to create depth of colour and by our other mens jewellery designers often with black diamonds in a pave setting, colour treated diamonds are natural diamonds that have been irradiated to alter their colour. This treatment creates a highly stable, permanent colour change to the stone. Harder than any other stone the diamond is perfectly suited to jewellery that is worn every day.
