Loyal to the finest Italian goldsmith tradition, Pomellato creates top quality jewellery in a constant quest for the perfect mix between creativity, stylistic consistency, innovative technology and craft skills. Pomellato jewels are made in yellow, white and rose gold, and alloys have a 750/1000 title. Pomellato Argento jewels are made using natural untreated silver, and the silver alloy used has a 925/1000 title.
The term ‘hard stone’ is improperly used to designate semi-precious stones, so as to distinguish them from more precious stones like sapphires, rubies, diamonds, etc. All gemstones are classified according to different indexes, one of which is the hardness index, specifying the level of resistance to scratching and chipping. Gemstones traditionally used in jewellery generally have a high hardness index, but it goes without saying that, as hard as a gemstone may be, it is not necessarily indestructible, and a gemstone set in an item of jewellery will still be delicate. Even small knocks, though not deliberate or direct, may scratch or chip a gemstone. Diamonds themselves, which are famous for being the hardest stones in nature, are not immune to breaking. For all of its jewels, Pomellato chooses exclusively natural gemstones carefully selected by expert gemmologists according to strict quality standards that Pomellato applies as a guarantee to its products.
Each Pomellato jewel is made exclusively with 100% responsible gold, sourced via Kering Responsible Gold Framework, extracted from certified mines that comply with international laws on the transparency and traceability of raw materials (RJC certification), or coming from production chains engaged in important projects to improve environmental sustainability.
All diamonds used in Pomellato Collections are purchased by RSJ certified suppliers: the goal of RJC is to define a responsible supply chain respecting human rights, protecting environment and attending correct management practice. White diamonds have clarity VVS-VS and G-H color, while for black, brown and icy diamonds it is not possible to apply 4C quality standard. In such cases color ranges of materials, clarity level, shining and cut are defined by the Company. All black diamonds have been subjected to heating treatments, to obtain a solid color. Such treatments are not considered dangerous for health and safety of our customers.
Every Pomellato jewel is made to be worn every day and on every occasion. This is why no extraordinary maintenance is needed, especially if it is delicately handled and cleaned. Nonetheless, being a precious object, it deserves to be treated with care. It is normal for both silver and gold jewelry to lose their shine with wear and over time. The natural phenomenon of darkening, due to oxidization, is also very common to all silver or gold alloy jewelry and it can be easily cancelled by a professional cleaning if the oxidation stage is advanced. We do not recommend any kind of do-it-yourself cleaning, especially in case the item is set with precious stones, diamonds or enriched by enamel or with leather. Professional help is also required to restore surfaces such as rhodium plating or burnishing. Stones set on a piece of jewelry are intrinsically delicate, meaning that even accidental or unnoticed bumps, as well as thermal shocks, could damage or break them. If you want to preserve the shine of Pomellato jewelry, we recommend you to store it in a clean, dry place away from any heat sources.
A jewel in natural untreated silver, worn even every day with care, will only occasionally need exceptional maintenance, especially if it is delicately cleaned from time to time and put away appropriately. Normal everyday use and external agents such as atmospheric humidity, temperature, pollution levels, contact with cosmetic products and perspiration may dull the lustre of silver surfaces, or alter the original appearance of the surface finish present in some items. The phenomenon whereby silver lustre is dulled and the surface becomes darker and more opaque, scientifically known as "tarnishing" and commonly called oxidation, is well known in metallurgy. The extent and speed of this phenomenon cannot be predicted, since they depend on a number of factors. To keep the oxidation problem under control and reduce it, the general rule is to prevent silver jewels from coming into contact with detergents, creams, fragrances and water, in particular swimming pool water (chlorinated) and sulphur springs, and it is advisable to regularly wipe the jewel surface gently with a soft cloth, being particularly careful with the finish and gemstones, if present.
Damage from contact with mercury, caused for instance by the accidental breaking of a thermometer, is the most severe damage a jewel may suffer – and, unfortunately, in most cases it is irreversible. Mercury creates an amalgam with gold, and often jewels cannot be repaired. In order to restore the original state of a jewel, as a first step it is fundamental to remove mercury. This can be done only with a high-temperature process which is highly toxic, since mercury vapours are extremely toxic. At the end of the treatment the jewel surface becomes extremely porous, making it unlikely for the original appearance of the jewel to be restored. Moreover, the colour of the alloy will differ from the initial one, since it is very difficult to remove mercury completely.
Jewels in white gold may tend with time to turn yellow. It is a well-known phenomenon, characteristic of white gold alloys, that in some cases may be accelerated by reactions to external agents. However, since it is only on the surface, it can be avoided or easily overcome by periodical cleaning with purpose-made products. However, if the jewel is rhodium-plated, the yellowing may be the result of the loss of lustre of the cold component of the rhodium-plating process and thus the emerging of the warmer colour, characteristic of the natural white gold alloy. In any case, also rhodium-plating is a surface treatment that can be easily restored.
Sandblasting, like rhodium-plating, is a surface finish that tends to alter with wearing. Sandblasting, in particular, is a treatment that enhances the superficial roughness of objects, creating peaks and troughs that can be seen and felt when touching. Wearing a jewel will tend to smooth out these peaks and troughs over time, and the surface becomes more glossy. However, the sandblasted finish can be easily restored.
For fabric cords and bracelets it is advisable to ensure as little contact as possible with water, spa water, soap, cosmetics, perfumes, detergents, chlorine and other similar substances which might fade their colour or cause a deterioration of the fabric to the overall detriment of the object itself. It is also advisable not to put fabric components to excessive strain which may cause them to break, by stretching them or attaching additional charms for which they are not intended.
