Our specialization is in Emeralds from Colombia, Rubies from Burma, Sapphires from Siam and Ceylon and fine Gemstones from Africa as Spinel, Tsavorite, Tanzanite, Garnet, Aquamarine and others.

We are cutting significant stock of high quality gemstones in order to offer a large choice of variety in color, sizes and shapes, pairs, sets and calibrated series.
While looking for new gemstone cuts our company was able to develop the innovating ”Double Rose Cut”.

A graduated gemologist F.G.G. guaranties the quality control and certification of each single stone.
Before being sold the gemstones pass a three step system: Identification, Grading and finally Evaluation.

The intensive relationship with customers from all over the world gives us constant motivation to improve our know how and professional skill, based on Italian creativity and German precision.
