Message us on WhatsAppCatalogueNatural Diam Srl is a supplier of natural rubies based in Milan, Via Giuseppe Mazzini 16. We supply certified rubies to jewelers, workshops, resellers, dealers and collectors across Italy and Europe, with offices in Mumbai and Bangkok as well.
If you are looking for a supplier of rubies in Milan or Italy, we work with certified stones from 2 carats. Every stone comes with a report from a recognised gemological laboratory, stating type, origin and treatment.
We work with reports from the leading gemological laboratories: Gübelin, SSEF, GRS and Christian Dunaigre. The report is the foundation of any wholesale purchase. It confirms the stone is natural, where it comes from and whether it has been treated.
For every ruby we state the origin and treatment clearly. In the online catalogue we separate unheated stones (No heat) from heated stones (Heated), so you choose with the right information in front of you.
We use the trade terms as the laboratories report them. Pigeon Blood is the description reserved for the most prized red in rubies, and Burma refers to Burmese origin, among the most sought after by the market.
We keep these terms in English because they are the ones used on reports and by dealers worldwide. If you need a specific colour or origin, message us and we reply with the stones available.
Heating is a common treatment for rubies and sapphires, and the report states it explicitly. An unheated stone and a heated stone can differ greatly in value, so the laboratory report is what establishes what you are buying.
That is why we never describe a stone in words alone: we show you the report. Ask for the report, photos and video of the stone you like, and compare origin, treatment and carat weight before you decide.
The process is simple. Browse the online catalogue, pick the stones you like and message us on WhatsApp with the stock number. We reply with the report, photos and video.
If you do not find what you need, describe the size, colour and budget: we search among the available stones and propose the closest alternatives.
We sell wholesale, not retail. The online catalogue shows the available stones with carat weight, origin, treatment and laboratory. For reports, photos and videos of a specific stone, message us on WhatsApp at +39 351 397 6900.
Tell us the size, quantity or carat weight you need and we reply with options. We work from Milan and supply customers across Italy.
