Can I bring Grandma's ring?
You are more than welcome to bring any old jewellery, metal and stones, that you may have. We will have a look at it and discuss our offer with you. Offers are usually cash or credit and don't worry, we are not stingy.
How do I choose a metal?
Sterling Silver (hallmarked: 925 or SIL) consists of 92.5% fine (pure)silver and 7.5% copper. The copper is added for strength since the metal in its pure form is too soft for the production of jewellery. Fine silver is a pure white metal and tarnishes slowly. Sterling silver tarnishes slightly faster in an oxygen rich environment due to the copper content and exposure to household chemicals, but can easily be cleaned and restored to its former lustre. Sterling Silver generally requires no plating, although some manufacturers do add a layer of Rhodium or Fine Silver to delay tarnishing.
9K Yellow Gold (hallmarked 375, 9ct or 9K) consists of 37.5% fine (pure) gold and 62.5% other metals (usually silver and brass). The other metals are added for strength due to the extreme softness of fine gold and 9K lends itself rather well to designs with stones set in claws due to its higher resistance to general wear and tear. The colour of the metal is a slightly lighter yellow than 18K and tarnishes ever so slightly with time due to the copper content and exposure to household chemicals, but as with silver it can easily be cleaned and restored to its former lustre.
18K Yellow Gold (hallmarked 750, 18ct or 18K) consists of 75% fine (pure) gold and 25% other metals (usually silver and copper). The higher gold content means that the metal is more expensive and softer than 9K, but it does not tarnish at all and has a deeper yellow colour.
White Gold 9K and 18K:
White gold is a mixture of fine (pure) gold and white metals (usually silver and palladium, but may contain nickel in mass produced pieces) which are added to lighten the colour of the alloy. Its alloys consist of the same gold content as that of yellow gold and are also hallmarked in the same way. Due to the nature of the alloy, the metal is never quite perfectly white and therefore it is covered with a layer of Rhodium plating to make the item appear perfectly white. This Rhodium plating, though considered the norm in the retail environment, eventually wears off exposing the grayish or sometimes yellowish colour of the metal underneath and therefore needs to be redone from time to time. We use an alloy with a higher palladium content than that of the alloys typically used in mass produced jewellery and therefore our white gold has a lighter colour and could be used without the plating, depending on the personal preference of each client.
Palladium (hallmarked: Pd or PAL) is a metal in its own right and is part of the platinum group. It is a white, sometimes slightly grey metal, usually alloyed with 5% ruthenium or copper (995 Pd), with a generally lower price per fine ounce and a lower specific gravity (meaning the weight per volume of the metal) than that of platinum making it more affordable and preferable to white gold because of its colour and the fact that it requires no plating. The metal is brittle when worked with by hand and so the preferred method of manufacture is through 3D CAD design and casting, but delivers a product with much the same properties as platinum at a lower price.
Platinum (hallmarked: Pt or PLAT) is the most expensive metal widely used in the physical manufacture of jewellery items. It has a higher specific gravity than most metals (about double that of silver) and thus the metal weighs more per volume than items manufactured in other metals and because of the generally high price per fine ounce, the input cost on the metal alone is quite high. Platinum is also an extremely difficult metal to work with since it contaminates easily and requires more labour intensive finishing due to its high density. It is extremely versatile and malleable, is like palladium usually alloyed with 5% ruthenium or copper (995 Pt), has a white or slightly grey colour and high polish and requires no plating of any sort since it does not tarnish at all. Due to its density it is more resistant to wear than gold, and is thus preferred for claw settings.
Titanium is not a precious metal but has none the less become very popular in jewellery as a metal for especially gents wedding bands due to its unique properties. There is a general misconception that titanium does not scratch. This is a fallacy. Titanium is highly resistant to scratching, due to its toughness and high strength-to-weight ratio, but it does scratch, albeit not as deeply or as quickly as precious metals. The colour of the metal is a darkish grey but it can be coloured through heat treatment or anodizing to produce a layer of brightly coloured oxidation in a wide range of colours. This is a tricky process and takes a practiced hand to produce accurately. Titanium combusts when it is heated to melting point in an oxygen rich environment, and therefore all casting and rolling of this metal is done in industrial factories under controlled conditions. For the manufacture of jewellery titanium can be milled or pierced from a solid, but it cannot be soldered at all and bending it poses problems due to its tendency to want to return to its original shape. For this reason our titanium rings are custom made to the exact size and, as with all titanium rings, needs to be replaced if the finger size changes.
