"Everything in this World is ephemeral. Except for diamonds. Some of them are more than 3.5 billion years old. After they are formed under tremendous heat and pressure, they rest in the Earth’s crust for another several million years. Then, they are pushed to the surface by violent, volcanic ruptures. Only the toughest, most enduring diamonds survive the dramatic journey. Natural diamonds are a piece of Eternity, and so is your love. Let your precious diamond be handled with excellence”.

The Provenance of the Diamond

Some years ago, we lost our hearts to the diamond. Completely. Unequivocally. The natural diamond has incredible optical properties. It is a superior material, tout court. However, there is more than strength & endurance, glitter & sparkle to the diamond.

There is stillness.

The diamond connects us to the deepest part of our existence. To the Earth – beyond time and form.

We help our customers express true love with the diamond, and sometimes: ONLY diamonds will do.


It is our absolute privilege to source and select only the most stunning diamonds for our clients. At Betsey Sook, clients do not need to have prior knowledge about diamonds, just as you do not have to be a sommelier to enjoy great wine.

When you choose fine jewelry from Betsey Sook, you buy diamonds from a certified diamond grader with the prestigious Diamond Grader's diploma from the Gemological Institute of America, your guarantee of the highest level of diamond knowledge and professionalism.

At Betsey Sook, we cater to clients, who seek premium quality.

We can provide classical round diamonds as well as a palette of fancy cuts such as oval, marquise, cushion, princess, radiant, emerald, pear, and rose cut diamonds. We can also procure rare diamond cuts such as old European cut diamonds and old mine cut diamonds, kite-shaped diamonds, and trillion cut diamonds.

At Betsey Sook, we have a highly advanced security system in place to thoroughly check the quality of each individual diamond. To the best of our knowledge, all our diamonds are natural, unheated, untreated, uncoloured and ethically sourced.
