We’re where the raw material is mined

We directly select the most beautiful raw natural stones in their places of origin. Stones are then processed in Sanda’s Italian and Southeast Asian cutting factories. Our volumes are at such a level to guarantee excellent buying conditions and continuative provisioning. This is the reason why we have become reliable suppliers searched by the most important brands of the Italian and international jewellery sector. Our selection around the world of raw materials is extremely rigorous and allows us to provide our clients with an extraordinary range of natural and synthetic stones: corundum, spinel, beryl, tourmaline, garnet, aquamarine, and all the quartz, cubic zirconia, hydrothermal quartz and semiprecious stones of all types with customized cuts.

Natural Stones

Today they represent our pride, from the finding of the raw to the cut. We are able to offer our customers a wide variety of materials, which we cut and combine according to their indications. We are always looking for new materials to continue pushing towards innovation without ignoring the power of tradition. We work alongside the style centres of the companies we serve, making our know-how on materials and trends available to designers and always trying to discover new finishes. In recent years we have promoted the use of doublets, combinations of stones that enhance the materials and introduce new colours, thanks to daring combinations.

Lab-Created Stones

Since the advent, during the last century, of more accurate methods for the study of the properties of minerals and crystals used for ornamental purposes, scientist made many attempts to artificially produce exact copies.

Synthetic gems must have the same chemical composition as natural gemstones of the same species. Furthermore, to have commercial importance, they must be obtained in crystals large enough to be cut and cheaper than natural materials.

The methods used for the synthesis and growth of the crystals are numerous, from the methods based on the simultaneous use of high temperatures and high pressures, to the growth from a molten material having the same composition as the desired crystal, to the crystallization from a solution which can be watery, as in the hydrothermal method used for the creation of synthetic quartz.
