How to Choose a Brown Gemstone
When selecting a brown gemstone, consider the following factors:
Colour
Colour is often the most important value factor. Rich, evenly distributed brown tones are generally preferred, although gemstones displaying secondary golden, reddish, or greenish hues can also be highly desirable.
Durability
Harder gemstones such as brown diamond are better suited for jewellery intended for everyday wear. Softer gemstones may require protective settings and additional care.
Rarity
Some brown gemstones, such as fine andalusite and dravite tourmaline, are less commonly encountered and may appeal more to collectors seeking something distinctive.
Budget
Brown gemstones are available across a broad range of price points, from affordable smoky quartz and tiger’s eye to premium brown diamonds.
Certification
Independent gemstone testing can provide valuable information about a gemstone’s identity and characteristics.
