購入購 Ruby 宝石(1)
It would be very difficult to find a gemstone with more prestige and fame than the ruby. In the language of the ancient Hindus, Sanskrit, it was known as Ratnaraj, 'the king of precious stones' and sought after by kings, emperors and maharajahs throughout history.
As soon as you hear the word ruby the color red will pop into your mind. Not just any old red but an intense deep red that inspires passion and desire.
A ruby has to be red otherwise it is NOT a ruby but the color can range from a deep blood red to an almost orange-red with purple, brown or pink shades found in some examples.
Which is the best color is a matter of personal preference but the purer the red the more valuable the stone.
Rubies are the red variety of the mineral corundum. Corundum can also be blue, yellow, green, orange, in fact just about any color you can imagine but if they are not red they are sapphires.
There are also Star Rubies Ã¢â‚¬â€œ created by rutile inclusions which have a star-like display on the surface of a cabochon cut stone.
What are the spiritual benefits of Rubies
To ancient Vedic astrologers ruby represented the sun and was one of the most powerful medicinal gemstones. Others referred to rubies as the Stone of Love. A few of their powers and virtues include:
- Power and Leadership
- Courage and Strength
- Passion and Energy
- Sexuality and Fertility
Ruby and the Chakras
The Chakra philosophy was developed in India thousands of years ago and linked energy centers located around the body to good physical and emotional health. Each spot has a dominant color. The Root Chakra is red and ruby is the most powerful red gemstone so they make a perfect team.
The main factor in the price of a ruby will always be its color. The color of a ruby is determined by the hue, tone and saturation.
The hue is the actual color of the gem as well as any underlying color Ã¢â‚¬â€œ too much orange or too much purple can devalue a ruby.
The tone is how light or dark the gem is. Too dark will affect the ruby's brightness and too light can make the ruby appear pink.
The saturation is vividness or intensity of the color Ã¢â‚¬â€œ a deeply colored, vivid ruby is a real find. Some rubies can fluoresce Ã¢â‚¬â€œ glow under ultra violet light Ã¢â‚¬â€œ which can enhance the intensity.
The perfect colored ruby has been described as pigeon blood red, usually found in Myanmar (Burma), but these are extremely rare.
The general rule with any colored gemstone is the bigger the stone, the bigger the price. Of course there are factors like clarity, the quality of the cut and the intensity of the color to consider but carat size will always be important.
Finding a quality ruby over 1 carat is not easy and as they increase in size, they increase in value significantly. A 2 carat ruby will be a lot more expensive than simply twice the price of a 1 carat ruby gemstone and a 5 carat ruby will be likely to be 25 times the price of a 1 carat gem all things being equal with color and quality.
It is very difficult to show an accurate price guide for such a diverse gemstone Ã¢â‚¬â€œ heavily treated stones can be snapped up for as little as $15 a carat while heated rubies can be $250 - $10,000 per carat according to the size and color. A 25 carat untreated ruby sold for over $1m per carat recently!
Rubies are usually heat treated in one way or another to make them presentable for sale to the gemstone market. Without these treatments being available there would not be enough rubies to satisfy the demand. It is estimated that untreated rubies that are acceptable enough to be sold are so rare that they make up only 1% of the worldwide ruby market.
Traditional heat treatments are generally accepted in the world of gemstones and are not controversial in any way so long as it is disclosed openly Ã¢â‚¬â€œ we at GemSelect always state clearly any treatment one of our gemstones has received.
Other treatments include fracture filling, flux-enhanced heating, glass-filling and the like. This is not the time or place to discuss the ethics of such treatments other than to stress the importance of full disclosure.
No gemstone has been revered more than rubies since humankind first started appreciating the beauty and power of precious stones. The ancient Hindu texts known as the Vedas mention their virtues and the bible uses the ruby as an example of something of great value.
Until modern scientists could study the chemical and mineral make up of rubies, it was quite difficult to tell one red gemstone from another. It was likely that many gems identified as rubies were spinels or garnets, but only stones of the highest quality.
Where are Rubies found?
Historically Burma (now known as Myanmar) has been the source of the finest rubies including the famous pigeon blood colored stones especially the Mogok valley in the central highlands.
Thailand was also the origin of many high quality gemstones but both these countries have dwindling stocks and have been overtaken by countries such as Madagascar, Tanzania and Mozambique as suppliers to the world.
The traditional sources of Myanmar, India and Thailand still have the esteem that can add value to a ruby but the countries of eastern Africa are catching up.
What jewelry is Ruby suitable for?
Rubies have a rating of 9 on Mohs hardness scale. This durability means that they can be used for any type of jewelry and can be worn daily without any concerns about chipping, scratching or breaking.
