Healing Properties
Popular belief suggests that ruby can enhance the positive parts of your natural energy while diminishing the negative aspects. Ruby is supposedly a stone of love and nurture, but is also associated with knowledge, wealth, and honor, connecting primarily with the root and heart chakras. It acts to stimulate the Kundalini energy, providing a full-body energizing and cleansing experience.
How to Select
Buying a ruby involves careful consideration of several factors:
1.Color: The color greatly affects the value of a ruby. The most sought-after color is typically associated with specific regions.
2.Clarity: A ruby with fewer inclusions is more desirable. However, certain inclusions can form a beautiful star effect, enhancing the gem's value.
3.Cut: A custom cut that maximizes light return or enhances color adds to its value. Common choices include brilliant cuts, step cuts, and emerald cuts.
4.Carat: Gem-quality ruby above 1 carat is rare, and prices increase dramatically for larger specimens.
5.Treatments and Synthetic ruby: Lab-created ruby is chemically and physically identical to the natural one but costs less. Be aware of undisclosed synthetics and simulated ruby made of glass or plastic.
6.Origin: Although ruby is found worldwide, the trace minerals vary subtly by location, leading to misleading trade names based on implied origins.
Remember to purchase from reputable dealers and consider getting an independent appraisal to ensure you're buying a genuine ruby.
Usage
Ruby is one of the world's best-known and most valuable gemstones. It has all the qualities required of top-class gems; hardness, durability, clearness, and good color. For this reason, they have been collected for millennia and used for all forms of high-end jewelry. Ruby is also used in the manufacture of lasers; the world's first laser was made in 1960 using a ruby rod.
