Lab Grown Diamonds Description
Lab grown diamond (synthetic diamond) is a kind of diamond crystal
synthesized by scientific method to simulate the crystallization
conditions and growth environment of natural diamond artificially.
Look from the product attributes, lab grown diamond and natural
diamond are crystals of pure carbon, has exactly the same physical,
chemical and optical properties, transparency, refractive index,
dispersion, etc as natural diamond, in brightness, luster, color,
flashing fire completely the same as the natural diamond jewelry
features such as lab-grown and natural mineral diamonds are real
diamonds, Different in nature from the imitation of diamond mossan
(carbon silica) and water diamond (cubic zirconia).
Characteristics Of Lab Grown Diamonds
| The Difference Between Lab Diamond And Natural Diamond |
| Attribute | Lab Grown Diamonds | Natural diamond | Distinction |
| Chemical composition | C(carbon) | C(carbon) | No |
| Refractive index | 2.42 | 2.42 | No |
| Relative density | 3.52 | 3.52 | No |
| Dispersion | 0.044 | 0.044 | No |
| Hardness value | 90 GPA | 90 GPA | No |
| Thermal conductivity | 2*103 W/M/K | 2*103 W/M/K | No |
| Thermal property | 0.8*10-6 K | 0.8*10-6 K | No |
| Light transmittance | DEEP UV TO FAR TR | DEEP UV TO FAR TR | No |
Resistivity | 1016 OHM-CM | 1016 OHM-CM | No |
Compressibility | 8.3*10-13 M2/N | 8.3*10-13 M2/N | No |
From a scientific point of view, cultivated diamonds are exactly
the same as natural diamonds, the only difference being where they
are formed.
Prospects And Advantages Of Lab Grown Diamonds
1. More and more recognized by the market
Lab grown diamonds have appeared in the global jewelry consumer
market from 2012 to 2015, but the product quality is poor and the
price advantage is not obvious. DE beers and other international
jewelry giant cultivating diamond jewelry market, overlay the
federal trade commission (FTC) for factors such as diamond justify
promote cultivation, lab grown diamonds in industry organization to
establish, specification development, synthesis and evaluation
technology promotion, production scale and market share increase
obvious progress, lab grown diamonds is recognized by the public.
2. More consistent with the trend of environmental protection
Lab grown diamonds has only one-seventh the environmental impact of
mining them. In terms of surface environment, the impact of lab
grown diamond on surface environment is only 1/1,281 of that of
diamond mining. In terms of carbon emissions, lab grown diamonds is
only one and a half billion times less than natural diamonds. In
terms of water resources, growing diamonds uses only 6.9 billion
times less water than natural diamonds. In terms of energy, the
energy consumption of lab grown diamond is only 1/2.1 of that of
natural diamond. In general, lab grown diamonds is in line with the
promotion of the concept of sustainable development in the current
society, and more in line with the pursuit of low-carbon and
environmentally friendly lifestyle of the young generation of
consumers.
