Mineral Sizing Guide

Understanding mineral sizes can help you choose the perfect specimen for your collection. Below is our guide to the standard size categories we use:

Category

Size

Info

 Thumbnail

Up to 3 cm

Thumbnails are small but well-formed mineral specimens that are perfect for display in thumbnail cases.

Miniature

Up to 5 cm

Great balance between size and detail - larger than thumbnails but still compact enough for easy storage and display.

Small-Cabinet

Up to 9.4 cm

Small-cabinet specimens offer larger crystal formations while still being easy to handle and display.

Cabinet

Over 9.4 cm

Ideal for prominent display pieces in a collection. Larger crystal formations and structure.
