What are lab-grown stones?

Lab-grown stones are synthetic minerals grown in the laboratory, which have the same characteristics as natural stones in terms of chemical composition, crystalline structure, and physical properties.

How are they made?

The realization takes place through the use of cutting-edge technologies that simulate geological processes.

The development process of synthetic stone can take place in several ways. In some cases, scientists simulate the same conditions the mineral finds underground; in others, the development will occur via the deposition of hydrogen and other carbon-containing gases.

compared to the synthetic one.

Jewelry made with lab-grown stones is highly appreciated in the fashion world because they represent a more convenient alternative for the customer. However, the duration of the jewel compared to that made with natural stone is undoubtedly different.

Understanding the difference between synthetic and natural is very difficult, even for experts in the sector. Therefore, when you make a valuable purchase, it is always good to ensure that the shop you buy from is not a retailer but a specialized jeweler. They will be able to issue the guarantee containing the stone's data and indicate whether the gem is natural or lab-grown.

Since 1871

The history of Biscioni Gioielli started in 1871, and it's a tale about tradition and craftsmanship, intertwined to form a design whose contours are the same as the Florence skyline.

Jewels are the opportunity to hold a dream in your hands, wear it, and recognize it in the admiring gaze of those who see it—a hidden yet full of meanings treasure.
