Lost Jewellery Recovery Service - Jewellery Reunited

posted by admin at 11/26/2019

Jewellery Reunited is a service run by The Guild of Jewellery Designers to help reunite lost or stolen jewellery with its rightful owner

The idea of a service to reunite people with their loved jewellery came about following a month of desperately retracing steps and turning our house upside down while frantically searching every room, twice sometimes three, with no luck. Finally resigned to the despair of losing my engagement, eternity and wedding rings ( I hasten to add, not even a year old, as we tied the knot in April).

However while getting ready for a change of hair colour, imagine my elation (well my husbands elation as he didn’t need to purchase them again), at finding all my rings inside a hair dye box (don’t ask). The following morning while lying in bed, dreamily admiring my rings back on my finger, I wondered if I could have them engraved with my phone number to enable them to be returned in the future, should I be unfortunate enough to lose them. (Luckily my husband is a fantastic laser engraver) Pondering if this would be feasible, a eureka moment occurred, why not enable rings to be engraved with a unique number registering them to their owner… and the rest, as they say, is history.

Can a Titanium Ring Be Cut Off?

posted by admin at 08/14/2018

There are 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. Titanium on the other hand is relatively soft in as much as it can be easily cut and marked, but has a high tensile strength which means that if you put it over your knee and had the strength to bend it, it would bend without breaking.

Tensile strength, in a nutshell, is resistance of a material to pulling force before it shears or pulls apart. Paper has low tensile strength, cake has very low tensile strength and Titanium and Titanium alloys have high tensile strength.

On a side note, an alloy, for those of you that don’t know, is a combination of different materials. For example Aircraft grade Titanium (Grade 5 or Ti/6Al/4V) is an alloy of 90% Titanium, 6% Aluminium and 4% Vanadium and has higher tensile strength than Grade 2 CP Titanium which is not an alloy but the element in its pure form.

Getting back to the original question, ‘Titanium Ring Removal – Can Titanium rings be removed in an emergency?’.

The simple answer is ‘yes they can’ and the process is exactly the same as for precious metal ring removal utilising the same tools.

Quite probably the main consideration when cutting off a Titanium ring is that the blade is brand new or very little used and preferably Tungsten Carbide.

A dull blade will struggle to cut the ring and will heat up the ring quite quickly. Lubrication is quite important too.

There are various different materials used for wedding rings, this article examines each material and its wearability rate.

1. Silver – A relatively inexpensive semi-precious white metal, reasonably soft and ductile and popular with men both as a fashion item and less so as a wedding ring. It does not resist scratching well and has a tendency to wear thin in time.

Another feature of silver is its reactivity with the acid in human sweat which tends to turn it black, although this tarnishing effect is easily removed.

2. Gold. 9 carat gold – fast becoming out of vogue with consumers in the UK in favour of 18 carat gold due to its low content of pure gold (37.5%). The low gold content also accounts for its paler yellow colour and in the case of 9 carat white gold, its whiter colour is due to the addition of silver or other whitening materials.

As with silver, 9 carat gold is prone to tarnishing but is arguably harder and more durable than 18 carat gold. Even so, it will not resist scratching well and, like silver, 9 carat and 18 carat gold will wear thin in time.

22 carat gold is also an alternative for wedding rings and is heavily favoured by Indian and Asian cultures.

3. Titanium. A recent newcomer to the wedding ring market, especially to the UK, Titanium is fast becoming the material of choice for the male market. Contemporary, modern designs coupled with strength and durability make rings from this metal the choice for discerning jewellery buyers.

Often mistaken as an indestructable metal, Titanium is in fact quite soft but extremely tough. It will take on small rub marks quite quickly but will resist deformation due to abuse or accidents and will not wear thin like precious metals. As with the majority of metals, with perhaps the exception of Tungsten, Titanium rings, if polished, will dull down, if satin, will brighten up and in time both finishes will meet somewhere in the middle.

4. Stainless Steel – Not as popular a metal worn as a wedding ring but still gaining recognition. About twice the weight of Titanium, and a highly durable material also. High resistance to deformation and wearing thin over long periods of time but, as with all metals will show signs of scratching.

5. Zirconium. Also a newcomer. As the sister metal to Titanium, Zirconium has all the same qualities – hypoallergenic, lightweight, strong, but with the added advantage that, when heat treated, forms a silky black, ceramic like, sapphire hardness oxide coating, Although extremely resistant to scratches, because of the soft material under the coating, dents will appear on the ring. The coating will resist chipping but you should be aware that scratches will eventually appear on the ring in time.

6. Tungsten Carbide. Yet another newcomer. Very hard, scratch resistant and durable and should retain its appearance for many years. The major disadvantages being that resizing is only possible by making the ring larger by remachining the bore using very specialist equipment and in the event that the ring has to be removed in an emergency, breaking the ring off is the only option and so destroying the ring.

7. Palladium. Not a newcomer but originally popular just after the 2nd World War. Palladium is in the same group of elements as platinum with practically the same look and whiteness but at a fraction of the cost. Durability wise – about the same as Titanium. The main disadvantage at the moment is the shortage of manufacturers producing rings from this material.

8. Platinum. The wedding ring equivalent of Royalty. Extremely expensive at the moment of writing but has gained a lot of popularity of late. Probably the whitest of all the wedding ring materials with the durability, once again, of Titanium.
