A Complete Guide to Star Ruby Gemstones
Star rubies are a truly mesmerizing variety of ruby gemstones. Renowned for their captivating six-rayed star effect, these gems are highly prized by collectors and enthusiasts alike. Let's delve into the fascinating world of star rubies.
What is a Star Ruby?
A star ruby is a type of ruby that exhibits a unique optical phenomenon known as asterism. This phenomenon creates a six-rayed star pattern on the surface of the gemstone when it is properly cut and polished. The star effect is caused by the presence of rutile inclusions within the ruby crystal structure. These needle-like inclusions align in parallel planes, reflecting light to form the star.
Formation and Origin
Star rubies, like other rubies, are formed deep within the Earth's crust under intense heat and pressure over millions of years. They are a variety of the mineral corundum, with the presence of chromium imparting the characteristic red coloration.
The most famous source of star rubies is Mogok, Myanmar. However, they are also found in other locations, including Thailand, Sri Lanka, and Madagascar.
Value and Factors Affecting Price
The value of a star ruby is determined by several factors:
Color: The most desirable color for a star ruby is a vivid, rich red.
Star Effect: The sharpness and clarity of the star are crucial. A well-defined, centered star is highly valued.
Clarity: While some inclusions are necessary for the star effect, excessive inclusions can diminish the gem's value.
Carat Weight: Larger star rubies are generally more valuable.
Origin: Star rubies from renowned sources like Mogok tend to command higher prices.
Care and Maintenance
Star rubies are relatively durable gemstones, but they require proper care to maintain their beauty:
Avoid harsh chemicals: Clean your star ruby with mild soap and warm water.
Store it safely: Keep your star ruby away from other gemstones to prevent scratches.
Have it professionally cleaned and inspected periodically.
