Vogue Singapore reported that the piece was created by the Singaporean jewelry brand Flower Diamond. Sabrina Ho, the brand’s marketing and communications manager, disclosed that Princess Azemah, Prince Mateen’s sister, had requested a tiara for her Jan. 2023 wedding that was "something simple, nothing too high or short, and something with a modern and lighter shape."

The princess also specifically requested the design to feature 838 large diamonds, all of at least VVS clarity and totaling over 132 carats, which were already owned by the royal family.

Flower Diamond’s creative director Roslind Ng then offered three designs to Princess Azemah, focusing on a modern and light aesthetic, as she revealed to CNA Luxury.

The creation of the tiara subsequently took eight months, involving meticulous planning and the crafting of bronze molds for fitting, to ensure a perfect finish. The availability of diamonds from the royal family’s collection expedited the process, which otherwise would have required additional time for stone selection, according to Flower Diamond representatives.

After its debut at Princess Azemah’s wedding, the tiara was adjusted to fit Anisha for her marriage to Prince Mateen, which was celebrated on Jan. 7-16.

This project stands as one of the most prestigious for Flower Diamond, reflecting more than 20 years of commissions from the Brunei royal family, as noted by the brand’s founder Belinda Chua. She also expressed her pride in being the first Singaporean jewelry brand to craft a tiara for a royal wedding, highlighting the significant trust the royal family has placed in her company.

Chua additionally remarked on the unusual occurrence of the royal family publicly acknowledging their jewelers, underscoring the commission’s uniqueness.

Anisha, a 29-year-old entrepreneur and University of Bath graduate who co-founded a tourism company offering cultural experiences, hails from a distinguished family closely connected to the Sultan of Brunei.

Her grandfather Pehin Dato Isa, an advisor to the Sultan, played pivotal roles in government during the 1960s and 1970s.

Her brother Danial Deen Isa-Kalebic is reportedly a close friend of Prince Mateen, and her sister-in-law Janetira Attaskulchai Deen is linked to Thailand’s Attaskulchai family, owners of the Betagen yogurt brand.

The ten-day wedding celebration of Anisha and Prince Mateen, 32, attracted approximately 5,000 guests, including international dignitaries.

Their first public appearance following the wedding was at the marriage celebration of Thai billionaire Aiyawatt Srivaddhanaprabha on Jan. 28.
