1, material: decorative earrings are usually made of some low-cost materials such as alloy, plastic or glass. These materials have low strength and oxidation resistance, which easily lead to skin allergy or discoloration. Gold earrings are made of pure gold or alloys containing a certain proportion of other metals. These materials have good strength and oxidation resistance and will not cause irritation to the skin.
2. Cost: The production cost of decorative earrings is relatively low, so the price is relatively cheap, generally ranging from tens to hundreds of yuan. The production cost of gold earrings is high, so the price is relatively expensive, generally ranging from several thousand yuan to tens of thousands of yuan.
3. Quality: Due to the limitation of materials and manufacturing process of decorative earrings, their quality is often poor, and they are prone to breakage and drilling, and skin allergies are also prone to occur. However, due to the advantages of materials and manufacturing technology, gold earrings have high quality and long service life.
