Q: What is the Nickel Release Content for your rings?
In the UK, for rings, it is currently 0.28 micrograms per square centimetre per week (0.28 µg/cm²/week) and the standard is BS EN 1811:2011 . All of our White Gold rings have been tested to the new standard and we have certificates of proof should our customers require them.
Q: Can I wear 9ct and 18ct Gold rings together?
It should be noted that 9ct and 18ct Gold should not be worn together as the 18ct will damage the 9ct. So, if a person has a 9ct and 18ct Gold wedding ring they should not be worn on the same or adjacent fingers.
Q: Can you do Two Colour in mixed metals, e.g. 18ct Outside and 9ct Centre?
No, we do not mix metals. But we do carry a wide selection of two colour rings of 18ct or 9ct respectively.
Q: Can you do 18ct Rose Gold plain rings?
Yes, but it may take 2-3 Weeks and costs an extra £40.00. See here our selection of 9ct rose Gold plain rings.
Q: What is the difference between re-rhodium and re-polish?
Rhodium is used to electronically plate (cover) White Gold to make it appear whiter. Only a White Gold ring would need to be re-polished, which removes the original rhodium plating, then re-rhodiumed to bring it up to 'showroom' standard.
Yellow Gold, Platinum and Palladium wedding rings only need to be re-polished to bring them up to 'showroom' standard.
Q: What is the content of your Platinum rings?
All Platinum Wedding Rings at Elma Jewellery, are made of 95% Platinum, 2.5% Copper and 2.5% Ruthenium, our Casted Rings (rings made from metal poured into a mould) are made up of 95.1% Platinum and 4.9% Palladium.
Q: Can you Diamond Cut on Platinum?
Yes, as you can see here our Platinum diamond rings. But, there is a limited range. As it is very difficult to Diamond cut on platinum.
Q: Can I wear Platinum and Palladium rings together?
Platinum and Palladium should not be worn together, like 18ct and 9ct Gold, one will damage the other. So, if a person has a Platinum and a Palladium ring, they should not be worn on the same or adjacent fingers.
Q: Is the 950 hallmark still valid if not in a 'house' shape?
When they are hallmarked by Sheffield (see Hallmark Section of Product Guide), due to the size of punch used, the 950 mark will NOT be in a 'house' shape but is still valid. This type of hallmark is known as a Convention Hallmark. In this case, the diamond shape around the scales indicates the ring is Platinum.
Q: What is the content of your Palladium rings?
Q: Can you Diamond Cut on Palladium?
Yes, We do offer a stunning selection of Palladium diamond rings, but there is a limited range, as it is very difficult to Diamond cut on Palladium.

Diamond can be set in rings starting from as small as 4mm, using the smallest diamonds - 2pt Diamond (0.02 carat) - and up.
Q: What does a 'D' prefix on a ring reference mean?

Yes. Please see this link for full explanation:
Titanium & Other Metals --
Q: Are all of your Titanium rings made from the same grade?
Yes, all of our Titanium rings are made from the same grade of Titanium - TA2.
Q: Does a Titanium ring with a Gold Band require a hallmark?
If the weight of the ENTIRE ring is more than 1 gram and is described as Titanium and GOLD (of any colour), then it MUST be hallmarked.
However, if the weight of the ENTIRE ring is more than 1 gram and is described as Titanium and YELLOW METAL, then it DOES NOT need to be hallmarked.
The hallmark MUST go on the precious metal.
Q: What is the composition of your Argentium Sterling Silver rings?
ARGENTIUM AG 960‰ PROFESSIONAL FOR CASTING
Argentium Sterling silver is a modern sterling silver alloy which modifies the traditional alloy (92.5% silver + 7.5% copper), by replacing some of the copper with the metalloid germanium. As it contains at least 92.5% silver content of the traditional alloy, these silver rings and jewellery are still referred to as sterling silver.
Argentium silver 960 is a high purity jewellery alloy that meets the hallmarking requirements for the U.K. standard.
Q: What is the composition of your Tungsten rings?
Our Tungsten wedding rings are a composition of roughly 86% Tungsten, and 14% Cobalt.
Hallmarking and other Tests --
Q: Which Assay Offices do you use?
Elma Jewellery uses the Assay Offices in Birmingham and Sheffield to test and measure our wedding rings content.
Q: Can you sell a ring without a hallmark?
No. It is illegal to sell a ring without a hallmark.
Q: Can you sell a ring with 2 hallmarks?
It is illegal to sell a ring with 2 hallmarks that are the same, that is if a Gold ring was stamped with 2 x 375 marks, it would be illegal to sell it. However, if a ring is made up of 2 precious or semi precious metals, for example Gold and Silver, then the hallmarks for both metals would appear on the ring.
Q: If a Product is made of Gold and Silver what hallmark is used?
The product receives two hallmarks, one for the Silver (which is first) and one for the Gold (see above too).
Q: Is a Hallmark valid if the Fineness (Purity) Mark (e.g. 375 for 9ct Gold, 950 for Platinum) is not in its
appointed symbol (e.g. gold is a rectangle, Platinum is a house-like shape)?
Yes, if the hallmark has its ‘Common Control Mark’ (the symbol with the scales), then the Fineness (Purity) Mark does not have to be in their appointed symbol.
Q: How is a Mixed Metal Ring hallmarked?
If a mixed metal ring weighs more than a gram and contains any colour of Gold, no matter that the Gold weighs less than a gram, the ring will require a FULL hallmark and must also be marked + metal on the Gold. If the ring has another mark inside, for example, Titanium, then the + metal mark won’t be required as the Titanium mark will suffice.
If a mixed metal ring weighs more than 7.78 grams and contains Silver, no matter that the Silver weighs less than 7.78 grams the ring will require a FULL hallmark and must also be marked + metal on the Silver. If the ring has another mark inside, for example, Titanium, then the + metal mark won’t be required as the Titanium mark will suffice.
The same principle applies to the other precious metals and their minimum weights - 0.5 grams for platinum and 1 gram for palladium.
However, if a customer does not want to hallmark the ring, as long as the two metals are distinguishable and the description is either, White, Yellow or Rose metal against the precious metal element, no hallmark is required.
