Each important jewel tells a story, which can be even more precious than the jewel value itself.
Quattrocolo Jewellery accompanies every jewel purchased by you, both antique and contemporary, with an expertise of authenticity and a gemological certificate with detailed origin and characteristics of each single gem.
This certificate not only guarantees you the authenticity of precious stones, but also provides you with important information on the gems mounted on your jewel (name, cut, size, number of gems, origin and carat weight).

EXPERTISE SERVICE. We also offer, by appointment, expertise service carried out by one of our expert consultants in our store on all jewels both antique and contemporary.

Our goldsmith workshop personalizes the jewels, rings, bracelets by engraving a name, a phrase or a date in different languages based on the space available and the existing technical constraints.
The engravings can be canceled or replaced by others.

We also perform threading services for necklaces and bracelets both simple or knots with one or more threads, of pearls and hard stones both own and purchased in our shop.

How many times do we leave a part a ring that has become tight or a necklace with a hook that no longer works, at the bottom of a drawer, giving up putting them?

CLEANING SERVICE
Our jewels are affected not only by the action of time and atmospheric agents, but often also by our habits. For this reason we thought of a jewel cleaning service, to give your jewels all the care they need, guaranteed by our qualified staff, who will treat them with the most suitable tools such as ultrasound washing machines.

To preserve the beauty of the jewels, it is recommended to follow our use and maintenance advice.
What we are going to suggest to you concerns only GOLD and DIAMOND jewels.

The jewel should be cleaned regularly, washing it with mild soap and water, using a soft bristle brush, then rinsing it with warm water.
It is very important that these simple steps to clean gold and diamond jewelry do not apply in any way to other precious and semiprecious stones (pearls, corals, amber, etc.) as in these cases they must be cleaned in a different way.

If you often wear PEARLS, have the thread checked once a year.
Avoid vaporizing perfume on pearls and do not use body creams.
Clean them with a damp cloth without soaps or detergents.
Place them separately in a case.

The most common problem of SILVER jewels is their oxidation, which is a natural process, but with proper maintenance and care it can be prevented. Specific products are available on the market that restore brightness to your silver jewel.
It is also advisable to remove the jewels before going to sleep, avoid storing them together because contact can cause scratches.

Remove the jewelry before practicing any sport, when washing your hands or using corrosive products. Avoid contact with perfumes, alcohol, cosmetics, ammonia and chlorine.
Where possible, we recommend that you bring the jewel once a year to your trusted jewelery store, to have it checked, cleaned and revived.

These services are carried out by expert jewelers who, in addition to their knowledge of the subject, have specialized machinery available.
It will also be an opportunity to check the solidity of the frame thus avoiding the possible loss of the stones as, over time, due to small impacts, especially if it is jewelry that is worn daily, the brands that support the stones may loose.
