The type of jewelry you own will determine the care and maintenance required. Generally, harder and higher quality materials, such as diamonds and platinum, will last longer and require less maintenance than softer, less expensive materials.
When it comes to repair or replacement, market and sentimental value come into play. With costume jewelry, it may be more cost-effective to buy a new piece instead of paying for repairs. Antique and high-end jewelry, on the other hand, will likely require professional maintenance and repairs.
