A: The difference lies in the gold content. Both 14K and 18K gold are popular choices for jewelry, but 14K gold contains 58.3% pure gold and 41.7% alloyed metals, making it more durable. On the other hand, 18K gold consists of 75% pure gold and 25% alloyed metals, offering a richer gold color but may be slightly softer. Your choice depends on your preference for color, durability, and budget.

A: Proper care ensures the longevity of your jewelry. To clean most jewelry, use a mild detergent and warm water with a soft brush. Avoid exposing your jewelry to harsh chemicals or abrasive materials. For specific care instructions, refer to our care guide provided with your purchase. We also recommend periodic professional cleaning and inspection to maintain the beauty and integrity of your precious pieces.
