Sayyid & Najjar Co.

Sayyid & Najjar Co. is a private diamond and luxury asset house established in Dubai in 1983. It specializes in rare diamonds, coloured gemstones, precious metals, fine jewellery, exceptional watches, and collectible luxury goods. The business operates as a trading house rather than a retailer, with no showroom or seasonal collection.

The company buys six specific categories: GIA, IGI, HRD, Antwerp, and AGS certified diamonds; unheated coloured gemstones from Burmese, Mozambican, Thai, and Madagascan origins; gold and bullion bars from recognized refiners like PAMP and Valcambi; signed jewellery from makers like Cartier and Van Cleef; luxury watches including Patek Philippe references; and high fashion items in sizes 25 through 40.

There is no fixed percentage applied to the asset. Instead, the price is determined by the international wholesale value of the specific item and the demand from someone in their network who wants exactly what the client holds. A GIA-certified diamond in strong demand may realize 50–70% of its original retail price, while a classic Hermès Birkin can frequently exceed its new cost.

The main office is located at Almas Tower in Jumeirah Lakes Towers, Dubai, United Arab Emirates. The trading desk operates from Sunday to Thursday between 09:30 and 18:30 GST, with private appointments available outside these hours by arrangement.

The process begins by sending a photograph and a certificate number, which is usually enough to start. The company provides an indicative range normally within 24 hours based on documentation and current market levels, followed by a physical inspection if required.

Assessment, authentication, and the written offer are all free of charge and carry no obligation. The company covers the cost of independent laboratory certification for qualifying items, such as origin determination on a coloured stone, and the client receives the report regardless of whether they sell.

The company trades under Kimberley Process certification and Responsible Jewellery Council principles. It is also a member of the Dubai Diamond Exchange and operates in compliance with UAE AML regulations.

The business maintains correspondent desks in Antwerp, London, Geneva, Mumbai, Hong Kong, New York, Singapore, and Istanbul. These locations allow them to arrange broker relationships and inspections internationally without requiring the client to travel to Dubai.

Clients need to provide details about the piece, such as carat weight, colour, clarity, cut, laboratory report number, maker, provenance, and condition. If all else is missing, a photograph taken on a telephone is acceptable to start the process.

After a physical inspection, the company makes a firm written offer. If the client accepts, funds are wired the same day. The entire process is confidential, and the client is under no obligation at any stage to proceed with the sale.

Founded in 1983 by two families already trading in the Gulf gem markets, the business has operated continuously through major economic cycles including the Asian crisis of 1997, the collapse of 2008, and the shutdown of 2020. The headquarters moved to Almas Tower in 2005.

Photographs in natural daylight, original boxes, papers, receipts, and service records are highly beneficial. Any laboratory certificates from GIA, IGI, HRD, GÜBELIN, SSEF, or AGS are also welcome to assist in pricing the item accurately.

A large share of the business is transacted internationally, and they can usually arrange broker relationships in London, Geneva, Antwerp, Mumbai, Hong Kong, Singapore, New York, and Istanbul. They also arrange insured shipping that they pay for if a physical inspection is needed.
