Anatomy of a Ring

The beauty of fine jewellery is in the detail. Even the smallest feature in your bespoke design is important to us, and to help you in the process of designing your dream ring, we’ve broken things down for you.

Centre Stone – Fairly obvious this one!<

Head/ Setting –The structure at the top of the ring (usually featuring a Centre Stone)

Claw/ Prong –Arms used to hold a stone in place

Side Stone – Stones positioned to the side(s) of a Centre Stone

Accent Stone(s) – Gemstone(s) set elsewhere in the design

Peek Stone(s) – Gemstone(s) set beneath the head, hidden from the down view

Gallery Rail – Discrete support bars to add to the setting

Bridge –Support beneath the Head to improves how the ring sits and fits on the finger

Shoulder – The upper section of the Band either side of the Head

Band/ Shank – This is the body of the ring that enables it to be worn

Sizing Area – Base section of the ring which is kept free of any design to facilitate resizing

Why Is It Important?

We at Durham Rose want to increase your education on ring knowledge. In doing so, when you are ready to design your forever piece, you can do so feeling empowered and ready to let your creative vision take centre stage.

Setting Styles

Your Forever Piece, Set In Style

What Is A Prong/ Claw Setting?

The term ‘Prong’ is utilised by American jewellery retailers and ‘Claw’ within the U.K jewellery sector. Prong or claw settings are the most common and popular way to show off your gemstone. The claw grips the stone around its girdle and hold it securely into place whilst showing off as much of the gemstone as practically possible, raising it above the shank becoming the focal point of your engagement ring. This setting is perfect for a delicate design piece.

4 Prongs/ Claw

Popular in contemporary jewellery, 4 Claw provides a simple but secure support for a gemstone.

6 Prongs/ Claw

Suitable for larger gemstones or to give an antique feel to a design, 6 Claw is secure and balanced style of setting.

Double Prong/ Claw

Creating a design feature from the Claws can add interest, while increases the contact area between the claws and the gemstone add security for larger stones

Bezel/ Rub Set

A narrow wall of metal to wraps around the stone, before being pushed over the very edges of the stone to hold it in place. Simple structure and clean lines make this style are popular with contemporary and Art Deco designs

Partial Bezel/Rub Set

Cutaways from the Bezel create a dynamic setting which can add shape and interest

Rex/ Crown

Popular with antique style jewellery 6-8 claw, tapering Rex settings resemble a crown from is where the name originates (coming from the Latin word for King)

V Claw

Recommended for gemstones with a point such as Pear and Marquise cuts. The V Claw firmly holds the corner(s) of a gemstone, securing them in place while protecting the delicate extremities of a gemstone

Ring Sizing

Fine jewellery should always fit well, too small and the ring won’t go on or will cause discomfort, too large and it will easily become lost or damaged. If you’re planning a surprise proposal then getting the correct ring size upfront can mean you’ve got to get creative! A reliable indicator is if you can measure a ring your partner already has (you can try it on your own hand and get that finger measured or take the ring itself to be measured by a jeweller), just remember to take note of which finger they wear it on and whether it fits!

If you’re absolutely stuck it can be helpful to know that the average UK ring size for a woman is and L – N and for a man is a S – T but averages are only useful up to an extent and your ring will quite likely need to be resized after your proposal. We offer one free resize on our bespoke rings but it is important to be aware that resizing is not possible for every design and in most cases a ring can only be adjusted by a maximum of two sizes up or down.
