The reason is the quantity of elemental silver in the 925 alloy which holds a higher vibration than the base metals used to make 14k gold-fill. Additionally, gold-fill is a high maintenance metal that can loose it's luster if not cared for properly (please see faq "gold & silver" & "basic care" for more information). Every package is tracked and fully insured.
Luxury gift packaging available by request. This item is made of prehnite and stone, silver, gold.
