INTRODUCTION

Some of these laboratory gemstones are very rare. They are generally used, for example, in laser equipment for satellites, missiles, or laser pumps in medical equipment. Its production and demand are very small and expensive, which also leads to a situation where we often face a shortage of supply.

They often use rare earth elements such as Thulium, cerium, praseodymium, neodymium, samarium, europium, terbium, dysprosium, holmium, erbium, and ytterbium.

Lasers have a wide range of applications, especially guidance, ranging welding, drilling, cutting, breeding, surgery, metrology and analysis, and have become a booming new technology.

PECULIARITY

Laser crystals are gemstones that possess properties that regular natural gemstones do not have, such as color, luster and reaction to ultraviolet rays.

Unlike natural gemstones, these laboratory gemstones are made from crucibles made of iridium gold and take many days to produce in an all-helium environment. The environment and temperature requirements are very demanding, which also makes them extraordinary quality.

Some of them are very rare, such as Cr3+:YAG known as cosmic laser, or CTH:YAG with its distinctive green color, or GAGG and LuAG with strong fluorescence.

Laboratory gemstones that have a natural counterpart (such as artificial diamonds, artificial rubies, sapphires, etc.) are not different from natural gemstones in terms of physical or chemical properties, and even have some properties. For example, in terms of gloss and size, laboratory gemstones can be more transparent and cheaper, which is beyond the reach of natural gemstones.But at the same time, we also sell many gemstones that have never been found in nature, such as laser crystals that can produce visible laser light under ultraviolet or neon lamp excitation, such as Nd:YVO4, Er:YAG, Nd:YAP, Nd:GGG, Nd:LMA, Ho:YLF, etc. Among them, Nd:YAG is more common, so they are also cheaper, which is widely used in various fields.

Yes, this is a question that very many people ask.
We have done extensive research on crystals that have been cultured in the lab. There are some crystals that are very toxic, but these are the ones that can be investigated.
We do not risk our own health by cutting toxic stones (either natural or lab grown) and obviously do not offer these types of stones for sale.
