Chopard 'Happy Diamonds Bow Tie' Watch in 18K White Gold

Authenticating jewelry and watches requires nuanced expertise. Many thousands of pieces of jewelry and watches have passed through our hands for over 40 years from every era and every maker. This familiarity enables us to know what a piece should look and feel like and if it has the expected quality of material and workmanship, the accurate makers marks and the correct signature in all the right places. Indeed, one of the easiest ways non-experts can be fooled is to assume a designer piece of jewelry is truly by that maker as pieces by commercial manufacturers are often outright fakes or signed fraudulently by a third party.
In practice, we first look at the front and back of a bracelet, ring, brooch or watch, turning it over in our hands to see that the workmanship on the reverse is just as fine as the detail on the front. Using the jeweler’s important tool, the loupe, we look carefully at many different touch points including the precision with which diamonds are mounted in their settings, the manner in which gold or platinum links are connected to each other, the fineness of the material used, the flawlessness of the polish and the quality of the azuring - a difficult and refined aspect of metalwork.
If we have any doubts whatsoever as to authenticity, we submit the piece to the relevant firm, be it Cartier, Van Cleef & Arpels, Verdura, David Webb and others. We also request the original bill of sale, box and papers for those items most commonly faked such as Cartier Love brackets and VCA Alhambra pieces. And just as banks know their customers we, too, ensure we know enough about our clients to assure ourselves of their ownership and provenance.
Our team of GIA-certified jewelry experts has such a well-regarded reputation in the international jewelry industry that we are frequently called upon to advise auction houses, appraisers and other dealers in matters of authenticity and value.

We stand behind every piece we sell with complete documentation, relevant GIA certification, and the best return policy in the industry, a full money-back guarantee, no exceptions.

Quartz watches, such as some but not all models made by Cartier, Tiffany and Bulgari are remarkably easy to maintain as they typically only require a new battery from time to time. Some jewelers recommend proactively servicing even a quartz watch to check the gaskets, clean the case and bracelet and to replace the battery every one to two years as leaky batteries can require a more involved service.

Watch cases, if made of gold or other precious material should wear well over time, but as with all precious metals, it is wise to treat them gently to prevent scratching. When not on your wrist, always lay your watch down on its side to protect the crystal face which can be scratched if rubbed against the bracelet or other hard material. Humidity, moisture and direct sunlight all contribute to wear and tear so whenever possible keep your quartz watch dry and wipe the bracelet occasionally with a clean soft cloth to remove accumulated dirt and oil.
