On the face of it, sizing a finger should be a fairly simple task. However, with the introduction in recent years of the comfort fit, which is the curved interior of a ring, and the fact that a ring stick can be measured 3 different ways by a jeweller (leading edge, centre, back edge), the process can be plagued with errors.

Ideally, the gauge used to measure a finger should be an exact replica of the ring being purchased i.e. have either a straight bore or a comfort fit bore and be the same width. There are variations to the comfort fit that can upset the apple cart in as much as the radius of the fit can be quite shallow, heavily domed or anything in between, hence the reason to use a gauge that has the same profile as the ring being bought.

Can Titanium rings be cut off in an emergency?

There seems to be a lot of myths and legends concerning this topic so I will try to put the record straight. Titanium is a material that is not particularly hard but is very strong and has a high tensile strength. Many people are unsure as to the difference between hardness and tensile strength and often get them confused. Let us consider diamond, the hardest material currently known to man. If you had a rod of diamond that was 25mm in diameter and 1 metre long, you wouldn't easily scratch it or mark it but if you try to bend it over your knee, you would probably find that it would snap like a carrot.

 

A laser, which is an acronym of Light Amplification by Stimulated Emission of Radiation, is a highly focused controlled beam of single colour light and can be used either to discolour the surface of a component or to vaporise material by laser ablation to produce a deep engraving. The laser parameters and position can be precisely controlled to provide high contrast marks in the form of barcodes, data matrix codes and logo graphics. If a surface is painted or anodised then the laser can be used to precisely remove the surface to give a contrast. By choosing a contrasting colour translucent substrate, a graphic can be backlit for night and day readability for example on car dashboards and aircraft cockpit controls.

What materials can be marked?

All metals (both precious and non-precious), most plastics, glass and many ceramics can be marked or etched.

Uses:

As the demand for more personalized items of jewelery has increased, many jewelers are appreciating the benefits of lasers and their engraving capability.

 

Zirconium - facts and fun by GETi.

Facts AND fun? I'm not so sure about the fun bit for this article. Having researched this on the internet all I seem to come across is a load of boring facts and figures, but here goes.

 

Titanium is the 22nd element in the periodic table and the first element in the group of metals known as Transition Metals. It was first discovered by clergyman William Gregor in 1791 who, basically didn't know what it was until in 1795, Austrian chemist Martin Heinrich Klaproth identified it as a new element, gave it the number 22 and named it Titanium after the Greek Gods - The Titans. 

 

This is a question that gets raised quite frequently.

Many Titanium-ring suppliers give a warning about taking care with getting the size right as it can't be altered in the future - this isn't strictly the case as it all depends on different factors.
