FREQUENTLY ASKED
What is gold-plated?
There is no standard metal or gold thickness when it comes to gold-plate. You can find gold plate in a variety of thicknesses and on a range of varying metals and alloys. With gold-plating, there is the high likelihood of the gold finish wearing out and chipping over time as the gold coating is very thin.
What is gold-fill?
Despite its somewhat misleading name, “gold-fill” jewelry is not actually filled with gold— it’s really the opposite. To make gold-fill jewelry, multiple layers of solid gold are pressure-bonded to a core of high-quality jeweler’s brass using extreme heat. (Industry standards dictate that your piece must be 5% solid gold by weight.) The result is a thick layer of real gold and a durable, long-lasting product.
Gold-fill jewelry is a great alternative to solid gold, as it offers the ideal balance of quality and value.
When it comes to deciding what type of gold you want for your piece, it really comes down to two main factors: how much you want to spend, and how long you want your piece to last.
Solid gold pieces will last virtually forever, but they are the most expensive option when it comes to gold jewelry.
Gold-fill pieces are just a step down from solid gold. For many customers, they offer the ideal balance of price and quality.
Gold-plated pieces are typically the least expensive option, but offer lower quality. These pieces could easily chip or flake and there are few standards about what base metal can be used. In rare designs where we find gold-plated to be necessary, we only use quality Sterling Silver as the base metal.
Gold-Fill:
Though gold-fill can naturally tarnish over time, it’s easily cleaned! We include a polish cloth in our packaging which we recommend using only when your piece is dull or tarnished—not for everyday cleaning purposes. It should be used “lightly” and not pressed hard against the metal to remove tarnish, as it could rub off the gold on your piece over time.
Rose Gold-Fill:
Rose gold fill is more prone to tarnishing than gold-fill because of the small amount of copper alloyed with the gold that gives it its beautiful pink color. but the same care tips that apply to gold fill also apply to rose gold-fill.
To prevent rose gold and gold-fill tarnishing:
- Avoid getting any product on your jewelry
- Clean it with mild soap and warm water and thoroughly dry it after wearing
- Store it in the storage we provided because it has added with extra felt protection to prevent oxidized.
- Avoid exposure to humidity
