Ruby is a kind of tourmaline with deep red and deep pink, especially the tourmaline with high color saturation and medium-dark tone, which has collection value. Red spinel is a ruby-colored spinel. The richer the color, the higher the value.
When judging which is more collectible, you can refer to the following aspects:
1. carat number: Generally speaking, the greater the carat number, the rarer the gem, and the higher the collection value. A 7-carat ruby is larger than a 2.5 1 carat red spinel. From this perspective, ruby may have a higher collection value.
2. Color: Color is one of the important factors that determine the value of gemstones. Ruby and red spinel are beautiful in color, but which color is more popular depends on personal preference.
3. Transparency and purity: The transparency and purity of a gem also directly affect its value. The higher the transparency and purity, the better the quality of gems and the higher the collection value.
4. Rarity: Rarity is also one of the important factors that determine the value of gems. If the output of a certain gem is scarce, its collection value will increase accordingly.
To sum up, to judge which is more collectible, we need to consider many factors, not just one factor. It is suggested that more consideration should be given when buying gems, so as to find the most valuable gems.
