Every week a reseller asks me the same question on WhatsApp: "Patrícia, how do I explain to the customer that this piece is different from the one she saw at the mall?" Here is what I answer. Five signals. You need no microscope or scale. You need a trained eye, and a trained eye is built by looking.
1. The weight in the hand
Pick up the piece and feel it. Well-made semijewelry has a base of brass or 925 silver, materials that have weight. Zamac bijouterie (a zinc alloy) is too light — you feel it is metalized plastic. If the piece is light without being delicate, suspect.
Even the finest pieces at Herreira have presence in the hand. It is on purpose.
2. The solder at joints
Look closely where two parts meet. In well-made semijewelry, the solder disappears into the metal — no line, no drop, no color shift. In a poorly made piece, the solder is visible, sometimes even gray or yellow because of the wrong material.
Bracelets with open links tend to give it away the most. Each link has to look fused, not glued.
3. The clasp
The clasp is where the piece suffers most. A lobster clasp must open and close firmly, with no halfway hitch. A buckle must catch the right hole without excessive force. An earring back must hold — if it is loose from the factory, it will fall at the first party.
I learned years ago to buy European clasps precisely because the national ones do the job, but the European ones do it for longer.
4. The reaction to touch
Run the piece across the back of your hand, the side of your neck. Well-applied plating is smooth, continuous, no roughness. If you feel grain, micro-bubble, any unevenness, the plating was poorly applied or is too thin — in a few weeks it will start to come off.
This test is tricky because a piece can look perfect to the eye and fail under touch.
5. The behavior after fifteen days
This is the most honest test. A good piece does not change in the first week, in the second, in the first month. If the customer comes back in fifteen days saying it darkened, lost shine, stains the wrist — it is thin plating or the wrong alloy in the base. No conversation: the piece has already told its story.
When you sell Herreira, this test plays in your favor. The customer comes back in fifteen days to buy something else.
The closing line I use with the customer
"You can wear it every day, in water, with perfume, with cream. I guarantee the piece. If anything happens in the first two years, it is my problem, not yours."
That sentence can only be said by someone who trusts what she is selling. That is the sentence Herreira has given me the right to say for eighteen years, and the sentence I want you to be able to say too.
