Mary of Teck bequeathed the Gloucester Tiara Collection, which includes the Teck Turquoise Tiara. Two generations of duchesses have worn the Teck Turquoise Tiara, which features an incredibly elaborate design that blends turquoise and diamonds. The Teck Tiara was once owned by Mary Adelaide of Cambridge and was a piece of turquoise-heavy jewelry.

The 1850-made outfit included three brooches, a necklace, and earrings. After Princess Mary received the set, she made the Teck Turquoise Tiara shorter. In 1912, E. Wolff & Co., a regular partner of Garrard, modified the Tiara according to Mary of Teck’s requirements.
