Look at the engraving
Tiffany's silver jewelry will be engraved inside, usually with the words TIIANY&CO 925 printed on it and the name given to it by the designer. If it is not engraved, almost 99% can be judged as a fake.
outer packaging
Tiffany's outer packaging is very delicate. Besides a special box, a flannel bag and ribbons are also included. Although some high imitations can imitate the packaged bags, Tiffany's unique colors can't be imitated, so after receiving the physical objects, you must first compare the colors, check the packaging and analyze them yourself.
Look at the technology
As a world-famous luxury brand, Tiffany's manufacturing technology is naturally very top-notch, so we can see many gaps when we look at the polished metal, and the genuine products are finely polished without unnecessary scratches. The imitation goods are prone to uneven polishing, and the workmanship alone will not pass.
