Ion Plating

What is ion plating?

Also known as IP Plating, this is one of the newest surface coating procedures and also the most advanced till date. It involves adding a titanium nitride layer to the base metal, in a vapour form. The end result is a harder and more durable surface which offers greater brightness and sheen than the traditional methods of plating.

The process of Ion plating

The high chemical stability of titanium nitride, which forms the surface layer in this method, is what gives IP plated surfaces their resilience and durability. To begin with, a layer of titanium nitride is added to the base surface of tungsten alloy. Additionally a final plating metal is added to the surface; the thickness of this layer is no more than 0.3 urn. This top layer is what gives the plating its colour. The process is carried out in a vacuum environment as low pressure has to be created for the evaporation of solid metal. Electric ions are produced when the vapour is heated and bombarded with electrons. This plasma is accelerated by the magnetic field induced, as it covers the base metal. Given its durability and chemical stability, ion plating is rightly called “permanent” coating.

Sizing Information

Ring Sizing Tips

Please note that ring sizing is a matter of comfort, above all: finger sizes fluctuate throughout the day and with temperature.
Additional information on ring sizing is available here: we recommend you check the size of a ring you currently love to wear against our sizing. We recommend you print out the attached pdf if you need help determining ring size: we do not recommend attempting to size using a mobile device.

Please note that most of our rings are classified as:

Sizable up or down by up to two sizes in half size increments: if the size you need is not available and falls within 2 sizes up or down of a ring we do have, we can likely size it for you. Charges will apply: see additional information on our ring sizing service available here

Sizable up by a half size: we can size the ring only up and only by about a half size: generally this is due to the detail on the piece and/or the setting of the stone. Charges will apply: see additional information on our ring sizing service available here

Unsizeable due to material or design constraints, the ring cannot be sized: the listed sizes are all that are available.


Additional Ring Sizing Advice

Temperature is Important

Don't measure when your body temperature is either too cold or too hot. A cold finger shrinks while a hot finger expands causing an inaccurate reading. Only measure when fingers are at room temperature.

When Two Sizes Seem to Fit

If you hesitate between two sizes, always go with the larger one.

A Wider Band Needs a Bigger Size

If you consider purchasing a wide band, move up a size from your measurement, for comfort’s sake.

Don't Use Strings

When measuring your finger, always refrain from using a string, they tend to stretch, which can result in wrong size. ALWAYS use a paper strip about 1/2" in width.

Big Knuckles Can Affect Your Size

If your knuckle is a lot larger than the base of your finger, measure both the base of your finger and your knuckle and select a size in between the two.

For Best Results, Use a Plain Band

Extra wide band styles tend to run slightly small. If you're borrowing a ring for sizing and it has a narrower shaft than the one you wish to purchase, you may wish to order a ring a size larger than the normal size worn. Also, large stone rings may cause the shank to lift up when laid on its side on the display, slightly distorting the size measurements.

Is There a Difference Between Sizes for Men and for Women?

No: ring sizes range in a continuous scale used for both men and women.


Chain Selection

Our pendants are sold with a Metalsmiths Sterling™ chain with a secure lobster clasp and logo tag of quality - the price includes a chain selected to best coordinate with the pendant. For most pieces, the standard length is an 18" chain, but more petite pieces may include a 16" chain and larger pieces may include a 20" chain: you can select your preferred length for any pendant upon purchase.

As a general guideline, 16" chains are considered choker length - pendants on this length of chain tend to sit near the base of the throat: 18" is standard or classic length, and usually lets the pendant rest near the collarbone or clavicle, above the collar of most shirts. 22" - 24" chains tend to sit a little lower, but still above the chest. 28" - 36" chains usually result in the pendant resting below the bust line and make for a more dramatic statement. The actual fit will vary from person: this is only a general guide.
