Canadian star Allie MacDonald wears 75 carat diamond piece to TIFF.

A 75 carat Ontario rough diamond necklace, worth $1 million, made its world debut on the red carpet last week.

The necklace, which was created by designer Reena Ahluwalia, was worn to the Opening Gala of the 35th Toronto International Film Festival (TIFF) by Canadian star Allie MacDonald.


The piece was commissioned by Crossworks-HRA Group in collaboration with iconic Canadian jeweller Birks and took one year to complete. It was mined, designed and manufactured in Canada and incorporates 27 un-cut, un-polished clear rough diamonds from the De Beers Victor mine in northern Ontario.

Ahluwalia said: “When I was commissioned this necklace, I wanted to design a statement necklace with an understated natural elegance. Rough diamonds were the perfect choice – understated, pure and just the way nature intended them to be.

“The necklace’s spiral design is inspired by the historic Mace of Ontario (Ontario Legislature)… I chose spirals for the beauty in their symmetry and what they conveyed – growth, advancement, energy and evolution. The spiraling form secures the rough diamond gently and is intended to portray social responsibility, signifying the diamond mine and the natural riches of Ontario.”

She added: “The raw brilliance of these rough diamonds is unmatchable. They are organic, inherently one-of-a-kind and make a strong statement about one’s identity, desire to return to nature and of course, diamonds conflict-free origin. To be able to hold these diamonds in your hand, as pure as a dewdrop and to know that they came from your backyard, is incredibly inspiring.”
