These are very heavy gold plated Brazilian Charms. These are known as Brazalian Gold-Filled Charms. These have 7 or more layers of gold on these.
Please keep in mind that not all things can be made in gold-filled due to the nature of how gold-filled is made. So if you are looking for certain charms that cannot be made in gold-filled and since plain gold-plated is not a good option as the plating can wear off then these heavy gold-filled charms are an ideal choice. These are fairly inexpensive. We have lot more items in this heavy gold plating material and will be listing those here soon.
