This is the lover's knot tiara once owned by the Maharajahs of Patiala. It's not clear exactly when the piece was made, or by whom, but the woman photographed wearing the tiara is Maharini Mohinder Kaur, the second wife of the Maharajah Yadavindra Singh. The two married in 1938; not quite ten years later, the couple saw the transition from British power to Indian independence. He became a diplomat and died in The Hague in the 1970s while serving as an ambassador; she's still alive today and is the rajmata, or queen mother, of Patiala.
This is speculation on my part, but I would suggest that it's possible that this lover's knot tiara was a twentieth-century piece inspired by Queen Mary's Cambridge version, given the strong ties between Britain and India. After all, it was Maharani Bakhtawar Kaur (mother of Maharajah Yadavindra Singh) who presented Queen Mary with the Delhi Durbar necklace in 1911 on behalf of the Maharinis of India.
