Our Story

The business started in the 19th century, when a young Dalsukh Das Tank first stared trading in rubies and natural pearls in the bustling markets of Calcutta. With each successive generation of entrepreneurial Tanks the business spread quickly, including offices in Bombay in the late 1800's to finally settling Jaipur in the 1905 and setting the stage for our greatest leader - Rajroop Tank.

The House of Tanks, as it is known today, has its origin in the 160-year-old establishment called Heeralal Chhaganlal Tank. Based in Johari Bazaar, Jaipur, our family-run jewellery firm has seen many industry pioneers, including the legendary Rajroop Tank and Dulichand Tank. The family’s legacy of dealing in exceptional quality coloured gemstones, including Emeralds, Rubies, Sapphires and Natural Pearls, has withstood very test of time.


His son, the stalwart Dulichand, carried the name Tank onto the international market by starting widespread export of cut and polished gemstones in 1956. Dulichand worked tirelessly towards revolutionizing the trade by bringing the world to Johari Bazaar. Together these two men imbued the name Tank with a trust, prestige and unwavering faith that lingers to this day.

Dulichand, like Rajroop before him, was highly involved in the growth and development of Jaipur and the Gem and Jewellery trade. Dulichand held offices like the President of the Jaipur Chamber of Commerce and Industry and board member of the Gem and Jewellery Export Promotion Counsel. 


Tank Fine Gems continues to procure raw material directly from the source, and manufacture this ethically mined and sourced rough within the in-house factory. The team of cutters and polishers have truly embodied the spirit of the House of Tanks. They strive for excellence with unwavering determination to deliver gemstones of the highest quality.

The firm is now onto its sixth generation and is currently being headed by Dulichand's son Dharmendra Tank. Dharmendra, an industry veteran in his own right, started his training under his exceptional grandfather at the age of seven, and today carries the same zeal towards his trade as his path breaking forefathers. He has provided the firm with the balance of modern machinery and traditional craftsmen-centered techniques that propelled them to the twenty-first century.
In addition to business, Dharmendra is also associated with various trade bodies and working for the enhancement of the gem and jewellery industry. He served on the Executive Committee of the Gem and Jewellery Export Promotion Council of India (GJEPC), was a member of the Board of Directors of the International Coloured Stone Association (ICA) and has been a part of the Valuations Panel for Coloured Gemstones for Indian Customs for the last 20 years.

A teacher extraordinaire, Rajroop  (affectionately called Chacha Sahab by his students), single-handedly trained thousands in the art of gem and jewellery, and thus remains revered by many within the trade. Being a man of many talents, Rajroop wrote a book on Indian Gemology and was also highly involved in state politics. He was also a true philanthropist as he helped establish many organizations like a school for the visually impaired as well as an all-girls school, one of the first of it's kind in Jaipur.
