🌍 Welcome to MicroMineralsUK on Etsy!
Thank you for visiting! At MicroMineralsUK, you'll find beautiful and rare mineral specimens and natural gems, carefully sourced from classic and newly discovered localities around the world.

🚚 Worldwide Shipping & Secure Packaging
We offer worldwide shipping, and each specimen is carefully packaged to minimise the risk of damage. If your item arrives damaged, we will either replace it with a comparable specimen or offer a refund — just return it with tracked shipping.

Orders can be combined for up to 1kg of postage weight.

🔎 Important Information Before Purchase
Please check the size and photos carefully before purchasing. We use macro photography to show fine details important to collectors. This can make items appear larger than they are.

Photos are taken under artificial light, occasionally inside a display case. Colours may vary slightly under different lighting conditions.

Full-specimen shots are usually provided so you can see the complete piece in context - request if wanted and unavailable.

Micromount boxes contain small samples, and many crystals can only be seen clearly with a loupe or microscope - a loupe is an inexpensive handheld eyeglass for visual magnification.
