Chain Styles

FAQs (Frequently Asked Questions)

What if I don’t like my birthstone?

If you don’t like your birthstone, no need to worry. No rule requires you to love it or wear it. Any jewelry item should make you feel good, so no need to be afraid if you favor alternative or ancient gemstones over the modern versions. 

If you aren’t a fan of your birthstone, you can get whatever gemstone you prefer. A person born in September can still wear tanzanite. There is no rule against it. Any jewelry piece should make you happy. Even if your preferred gemstone is another month’s birthstone, choose one that certainly speaks to you. What is crucial is that you enjoy wearing them.

What should I do if my birthstone is too expensive?

If you like how your birthstone looks, but you cannot afford it, you may consider finding other cheaper alternatives. Many precious stones share the same quality as others. For example, if your birthstone is diamond, you may opt for more affordable gems, such as cubic zirconia, moissanite, white sapphire, white zircon, white topaz, spinel, or colorless beryl.

You can also save if you pick smaller stones and cheaper supporting metals. One example is sterling silver, which is a budget-friendly alternative for white gold.
