Types of Lab Grown Gemstone
The lab grown gemstones produced by our company mainly include the following types:
Lab Grown Zambia Emerald
Its charming green color is due to the presence of chromium or vanadium elements. Zambian emeralds have excellent quality, and the quality of high-quality ones can be comparable to Colombian emeralds.
Lab Grown Columbian Emerald
Oval shaped Lab Grown Columbian Emerald often have high transparency and bright colors, especially pure emerald green which is the most precious, with bright, uniform, and dazzling colors. The interior of emeralds often contains several minor flaws, but the flaws in high-quality emeralds do not affect their overall beauty and luster.
● They are identical to natural gemstones
The chemical and physical properties of lab grown gemstones are identical to those of natural gemstones. Properties such as sparkle, hardness, etc. are identical to those of natural gemstones, and lab gemstones may even be superior in terms of color. Lab grown gemstones can be controlled for color balance, clarity, etc.
● Less risky to buy
Lab grown gemstones can control the quality as well as the appearance of the stone because they are grown under human controlled conditions. This also means that your purchase of a lab gemstone is a low-risk affair, with small chances of purchasing a poor quality gemstone.
Inexpensive
Lab grown gemstones are sold at a cheaper price than natural gemstones because there is no need to incur expenditures such as labor to mine the minerals, thus reducing costs. This can give more people the opportunity to own beautiful gemstone jewelry.
High customizability
Lab gemstones can be customized to produce colors that are very rare in natural gemstones, allowing you to get more distinctive jewelry.
Conflict-free and reduced environmental impact
Lab grown gemstones are made for laboratories, in line with the concept of ethical sustainable jewelry is more environmentally friendly and ethical. This is very friendly to those seeking to protect the environment and ethics.
Synthesis Technology of Lab Grown Gemstones
CVD method of lab grown gemstones
In the CVD method, a high-quality gemstone seed is positioned within a chamber. The chamber is subjected to heat, and gas is introduced. Within this environment, carbon atoms in the gas are disassembled, combining with the gemstone seed to generate additional crystals and ultimately form a gemstone.
HPHT method of lab grown gemstones
The HPHT method, in use since the 1950s, involves placing a gemstone seed on a carbon material. The seed undergoes high temperature and pressure, replicating the natural gemstone formation process beneath the earth's surface. This results in the creation of gemstone crystals, which, upon cooling, coalesce to form a gemstone. Over the years, advancements in this method have accommodated the escalating demand for lab-grown gemstones, facilitating the production of gemstones on a large scale and in less time.

● Avoid contact with chemicals: Chemicals such as cosmetics, perfumes and detergents may damage the surface or internal structure of some gemstones. It is advisable to remove gemstone jewelry before applying cosmetics, detergents or performing household activities.
● Avoid violent impacts: Even the hardest gemstones (e.g. diamonds) can break or crack after a strong enough shock.
● Regularly check your jewelry: Make sure the gemstones are securely set to avoid loss, and if necessary, take them to a professional jeweler for inspection and repair.
● Separate storage: When storing gemstone jewelry, it is best to use a separate jewelry box or wrap it in a soft fabric and keep gemstone jewelry separate to avoid them scratching each other.
● Gentle Cleaning: Most gemstones can be cleaned with warm water and mild soap, then gently brushed with a soft bristle brush, and finally dried with a soft cloth.
● Do not expose to high temperatures: Exposure to high temperatures or strong light may cause changes in the internal structure of lab grown gemstones, cracks or discoloration. Therefore, do not place your gemstone near a heat source or expose it to sunlight for long periods of time.
