A carat is a unit of weight for diamonds. 1.58 carats means the diamond weighs 1.58 grams. Generally, the higher the carat, the larger and more valuable the diamond.
Yes, a diamond pendant can be worn daily, but it should be taken off during strenuous activities to prevent damage. Silver settings may require periodic cleaning to maintain their shine.
Silver is a durable and affordable metal for diamond settings. However, it is softer than gold or platinum, so it might wear over time.
