How to Choose an Orange Gemstone
When selecting an orange gemstone, consider the following factors:
Colour
Colour is often the most important value factor. Vibrant, evenly distributed orange hues are generally preferred, although softer peach and honey tones are also highly appreciated depending on the gemstone variety.
Durability
Harder gemstones such as orange sapphire and imperial topaz are better suited for jewellery intended for everyday wear. Softer gemstones may require additional care and protective settings.
Rarity
Some orange gemstones, such as fine imperial topaz and vivid mandarin spessartite garnet, are less commonly encountered and may appeal more to collectors.
Budget
Orange gemstones are available across a broad range of price points, from relatively affordable hessonite garnet to rarer gemstones such as orange sapphire and imperial topaz.

Independent gemstone testing can provide valuable information about a gemstone’s identity and characteristics.
