There are a group of young guys who work very hard on “diamond”, they keep pursuing their diamond dream with passion & enthusiasm.
Yes! They are going to conquer the world with the revolutionary “diamond” just like their ancestors who took adventure through the black ditch from Tang Shan to Taiwan for their dream and bountiful future.
This dreamy team is led by Dr. Chih-Shiue Yan, the first person in the world to develop white CVD diamonds. They devised high-tech equipment and take advantage of the local natural resources: Mountain, Water, Sunshine, High-tech and Time to produce the glow diamond. We called it Alishan Diamond.
The profile of Dr. Chih-Shiue Yan:
from Carnegie Institution of Washington USA
the writer of “cow dung can grow diamond”
the first person to grow white CVD diamond
Forest、plant、animal… produce CH4
Hydrolysis produce H2
CVD-chemical vapor deposition
Solar generate electric power
Alishan Diamond will terminate the tragedy of blood diamond. Such as the ethical problems of squeezing & extort the labors, the conflicts and the murder …etc those cause from mining diamond for century.
Our Revolutionary new diamond technology will benefit our environment with Great friendliness and responsibility for good.
To make a continuous reproduction breed in an endless succession for our mother earth is our beautiful Vision
We define A-li-shan New diamonds as : Bountiful, Commitment, Deluxe & Everlasting !!
What is "synthetic diamond"? What is a "laboratory-grown diamond"?
And what are the difference with "natural diamond”?
Since hundred years ago, human beings are tried to synthesize diamond. After countless failures, they finally successfully synthesized diamond in the laboratory in last century.
Currently there are two methods to synthesize gem-quality of diamond, one is high temperature and high pressure (HPHT) and the other one is chemical vapor deposition (CVD).
However synthetic diamond or growing diamond is just another synonym of laboratory growing diamond.
Laboratory growing diamond and Natural diamond
Their appearance , components, physical and even the chemical properties are completely the same, excepting the method of how they grow.
Natural diamond is mined from the ground, yet laboratory-grown diamond is cultivated in laboratory. We can simulate the environment conditions of how natural diamond grew. Actually it is impossible to distinguish their difference with naked eye or with traditional instrument or methods. The way to identify them is only high-resolution of instruments can be. Their difference maybe only The clarity ”, Laboratory growing diamond is more “perfect", and its price is more “ affordable".
How to distinguish between "natural diamonds" and "laboratory grown diamonds"?
How to distinguish between "natural diamonds" and "laboratory grown diamonds"? Lab-grown diamonds have the same chemical and physical properties as natural diamonds, so they cannot be distinguished by the naked eye and only be identified using inspection instruments.
There are a number of instruments used to detect diamond. UV-VIS Spectrometer, FTIR and Raman Spectrometer. The following is an introduction to the above three instruments.
In UV-Vis spectroscopy ultraviolet and visible light illuminates a diamond and the absorption of certain colours is analysed. The UV-Vis spectroscopy data can be used to analyze the impurities (ions) of diamonds, further distinguishing between natural and laboratory diamonds. This method is not sensitive to white diamonds and often requires liquid nitrogen to cool the diamond.
FTIR is based on the vibration of molecules, and the absorption spectrum can be analyzed which functional groups are contained in the sample. Infrared absorption spectrometers can distinguish the amount of nitrogen in the diamond (Type I and Type II), and can also distinguish between natural diamonds and CVD diamonds by the absorption peak position of hydrogen. If the diamond is too small, the surface is too rough, or the color of the diamond is too dark, the signal is always too weak to judge the source of the diamond.
Raman spectroscopy is a spectroscopic technique used to observe vibrational modes in sample, and also to observe the fluorescence caused by the impurity defect. Raman spectroscopy has the advantage of distinguishing between natural and laboratory diamonds: diamonds do not need to be polished, diamonds size are not limited, diamonds do not need to be cooled, etc.

Do you know the laboratory-grown diamond can preserve value?
To count the greatest significance of diamond value in your life, We believe that laboratory diamonds are better than natural.
A couple will buy 1 carat of natural diamond with $10,000 USD
B couple who will spend $3,000 USD to buy 1 carat of laboratory diamond, and they got some balanced of budget for their honeymoon and for their investment.
Valuation of price list
Laboratory grown diamond as well as natural diamond are real diamond. Both of them can preserve the market value.
However, the mechanism of producing and marketing for laboratory-grown diamond is not like the natural diamond has been deliberated planning and hype, that lead to the rarity and monopoly.
Currently laboratory grown diamond isn’t like natural diamond has the value for resale, that’s because the mechanism of producing and marketing for laboratory-grown diamond is still immature.
As soon as the mechanism of its marketing has completed, the value of laboratory-grown diamond will be established for sure.
Inestimable pricelist and Irreplaceable preservation value:
The affordable price is the essence of laboratory diamond. Personalization and customization are the characteristics of laboratory-grown diamond.
The price is affordable, it makes Joy and happiness easily be carried out. It doesn't cost you lots of money to owned a deluxe diamond. It’s not like natural diamond so unreachable. Especially it is customized for consumers and who can create unique and individual value as your wish. It is remarkable and distinct from natural diamond.
Laboratory grown diamonds make your diamond priceless!
What are the advantages of laboratory grown diamonds?
Conflict free diamonds
Not to be a slaughter to squeeze & extort the labors in the area of mining diamond, Comply with the standard of eco-friendly and ethical. Minimizes the environmental degradation.
Value beyond what it is worth
