Calderoni: Certified diamonds to give as gifts
Calderoni was founded in 1840 on Via della Lupa, today’s Via Torino, in romantic Milan under the rule of the Habsburg dynasty.
The brand has always enhanced the qualities of Italian craftsmanship in creating elegant jewellery, through the careful selection of the finest stones and most precious materials, with exclusivity, creativity, and tradition: for Calderoni, creating a jewel has always been a challenge towards perfection, towards the ingenious, so much so that it has won the Diamonds International Awards, the World Oscar of jewellery, four times.
The house boasts nearly 200 years of experience in jewellery and in selecting the finest diamonds, further strengthened by the almost century-long experience of the Damiani group, of which it is now a part.
