Dear Customer

This short text explains how my company Diamonds & Jewelry Calandrini 1977 is structured


Underlying this is a strong passion for jewelry, precious materials and the pursuit of our Customers’ satisfaction.

Handling every request is Marco Calandrini son of art and master goldsmith with specialization in goldsmithing and metals, precious gems, especially diamonds, a passion handed down since 1977

On the other hand, for about 15 years we have been permanently based in Antwerp Belgium (where we can also receive you), the international and European headquarters for the import and export of IGI GIA and HRD certified diamonds, the only three gemological institutes that attest without any doubt anywhere in the world the quality of diamonds and precious gems such as sapphires, emeralds and rubies


Thanks to our Belgian location, we avoid any extra commercial steps for our customers which allows you lucky buyers to have any quality, quantity of diamonds at the best market prices

Once you have selected the gemstone(s) of our/your jewelry Calandrini designs, plans and realizes the masterpiece of your desires
Everything starts from a study and to a symbiosis of experience and needs of our Clients.

Having found the balance between demand and supply, the classic design on paper is transformed thanks to our designers into a cad design, which allows for single casting in any metal, yellow, white, pink or platinum gold.


Our goldsmiths have a minimum of 10 years of experience, and Diamonds & Jewelry’s three main goldsmith locations are located in Valenza Pò the world capital of jewelry making and creation and high jewelry.


Casting workshop, goldsmith finishing, microscope setting and laser polishing enable us to deliver you an elegant, refined and durable piece of jewelry complete with every guarantee.

In total there are as many as seven Diamanti & Gioielli goldsmith workshops, as many as twenty employees in diamond offices in all major diamond trading venues such as Honk Kong, Singapore, New York, Tel a Viv, Israel, Dubai etc….and each gemstone can be quickly viewed in our jewelry store or be conveniently delivered to your door by insured carrier by appointment according to your needs.

Diamonds & Jewelry works with passion to make your ideas unique or to make each of its jewelry special at the best market prices without sacrificing the certified high quality of the jewelry available or those to be made together according to your requests.

Calandrini Marco is present at every step of this process including the terminal part of the delivery with related pre-delivery quality control either for online sale at www.diamantiegioielli.it or in our jewelry store or upon delivery to your home.
