Frequently Asked Questions (FAQ)

About Products and Materials

Question: What materials are INTERO jewelry made of?

Answer: The INTERO collection is crafted from high-quality materials: a stainless titanium steel base with three layers of genuine 18-karat gold and sparkling cubic zirconia crystals. Our manufacturers guarantee that all INTERO products are nickel-free and safe for your skin.

Question: How are INTERO jewelry plated?

Answer: Our manufacturers use advanced PVD (Physical Vapor Deposition) technology to gold-plate the INTERO collection. The 18-karat gold is vaporized in a vacuum chamber and deposited on the stainless steel surface. This method, used by our manufacturers, creates a durable, scratch-resistant gold layer with a thickness between 0.03 and 0.05 microns on all INTERO jewelry .

Question: Is the gold in INTERO jewelry real?

Answer: Yes, at INTERO we use real 18-karat gold. Our manufacturers store this gold in thin sheets and rigorously inspect it for quality and purity before it is used in the gold plating process of INTERO jewelry .

Question: What is the difference between INTERO products and regular gold-plated jewelry?

Answer: The difference lies in the technology our manufacturers use. We use PVD technology and a neutron plating process that permanently fuses the gold to the steel. This makes INTERO jewelry much more scratch-resistant and durable than traditional gold plating.
