Let's not complicate things. This perfect sunburst pendant necklace is exactly what you are looking for. 

Details: 

• 18 Karat Gold Filled Sterling Silver 925
• Length: 15.7 inches (40 cm) 
• Pendant Diameter: 16 mm 

  Care: 

• To clean, gently buff the gold-plated item with a soft microfiber cloth.
• The added metals in sterling silver make it an incredibly durable material — it's even stronger than gold. In addition to its light weight, this quality makes it an ideal choice for jewelry that will be worn daily, but does require extra care.
• Do not wear in the shower, while swimming, sweating, or sleeping.
• When not in use, store in a dry area. (Not in the bathroom.)
• Wait to put on until after you have applied perfume, lotion, and makeup. Substances like oil, nail polish, nail polish remover, perfume, or chlorine can react with the sterling silver, causing it to tarnish more easily.
