Characteristics of Investment Gemstones

A gemstone is characterized by the factors of naturalness, beauty, and rarity. This sequence can be also regarded in ascending order as increasing in value.

Investment gemstones must be natural.

The beauty of a gemstone is defined by its cut, color, clarity, and carats (the "4Cs"). Its rarity is directly correlated with its geological rarity. The better and more rare each of its 4Cs is, the higher its investment potential.

Certificates are likewise an absolute must for investment gemstones.
