EMERALD

Emeralds have been always among the most expensive colored minerals and the market's need for high-quality analogues of emeralds has resulted in elaboration of the materials, which possess all the physical, chemical and optic properties of the natural stone. Such crystals are internationally referred to as created gems.

RUBY

Ruby is a red variety of corundum.
At all times red color has been associated with strong emotions, passion and love, power, fire and blood. Therefore, the flame- red ruby is the most popular stone since ancient times.

SAPPHIRE

RG Crystals offers created Sapphire, which is produced using the Czochralski method. Only this method enables creation of the large and pure crystals of recrystallized sapphire.

SPINEL

With some degree of irony, spinel can be considered as one of the "youngest" gems. The naked eye finds it difficult to distinguish spinel from a ruby and red spinel was long considered a ruby before science established a clear distinction between these two types of minerals. 

YAG

Yttrium Aluminium Garnets (YAG) belong to a group of specially developed materials, which have been used in quantum electronics equipment and laser technology since the mid-20th century. Yttrium-Aluminum Garnet is the Y3Al2(AlO4)3 oxide, which has a cubic crystal structure of natural garnet.

OPAL

Lab-grown opals are synthetic gemstones created in a controlled environment to mimic the dazzling beauty of natural opals. These man-made opals are composed of similar mineral components as their natural counterparts, such as silica spheres and water content.

BERYL

Patented advanced technology of RG Crystals enables customers to not only acquire an emerald but also a complete range of other beryl colors such as red or pink bixbite, pale pink morganite, green beryl of any color saturation as well as blue-green aquamarine.

CUBIC ZIRCONIA

Cubic zirconia is one of the most common and well-known materials in the jewelry market. Zirconium oxide is a mineral that is extremely rare in nature, but is also extensively synthesized. As for its chemical properties, cubic zirconia is a zirconium dioxide (ZrO2) with additive compounds of the yttrium oxide.

QUARTZ

Quartz is the most common mineral on the planet and the palette of quartz colors is very diverse. Apart from colorless or pure quartz, it can be a purple, orange, yellow, smoky, pink or black color. There is also a unique polychrome quartz, which is a crystal painted with two or more colors turning into each other.
