How to Choose the Right Karat for You?

When choosing the right karat for your jewellery, consider budget, lifestyle, skin sensitivity and aesthetic preference. Higher karat gold is more valuable and pure but softer and more prone to damage. Lower karat gold is more durable and affordable.

Purpose of the Jewellery

Consider the purpose of the jewellery. For everyday pieces like engagement rings or bracelets, 10K or 14K gold may be more practical because of its durability. For special occasions, gifting to newly wed or heirlooms, 18K or 24K gold may be preferred for its beauty and value.

Caring for Different Karat Levels

• 10K and 14K Gold: More durable, daily wear. Clean with mild soap and water, avoid harsh chemicals.
• 18K and 24K Gold: Softer and more prone to scratches. Handle with care, avoid abrasive materials, store properly to prevent damage.
