Diamond Time-Lapse
Origin
The journey of your diamond begins a billion years ago a hundred miles deep in the earth’s crust. The pressure is so intense that atoms of carbon crystallize into diamond, the hardest material on earth. Read about How Diamonds are Mined
Rough Sorting
Diamonds come in big lots of thousands of carat from the miner. On the receipt, every rough diamond is individually checked by the rough assort expert and evaluated based on its size, color, inclusions, etc.
Planning
The shape of a rough diamond is uneven and contains various types of inclusions. To get a sparkling diamond from an included rough diamond, it requires to be architected by an experienced and talented Artisan.
Laser Cutting
A diamond has to be cut in to various pieces according to the plan. The laser cutting expert gets the detail of the plan and takes up to 30 minutes to 2 hours depending on the size of the rough diamond to cut it.
Polishing
After the laser cutting, rounding and windowing, the polishing artisan has a clear picture of the inclusion and predetermined shape of the diamond. He then initiates the faceting on the diamond. The facets are so tiny that only a 10x or 14x magnification can help the artisan view them. Diamonds are faceted on a polishing wheel rotating at a speed of 3600 RPM.
Polish QC
The polish QC artisans evaluate the diamond based on their knowledge of the 4C’s and beyond. Around 60 parameters are checked by the artisans and then given the grade of a particular diamond. They also check for the changes and polish remnants left on a diamond while faceting.
Certification
Diamonds are polished and graded by the GIA. Their labs use high magnification instruments and test to determine that a diamond is of said quality and also check for any treatment on it. Authentication gives confidence and peace of mind to you, so that you know exactly what you’re purchasing.

We support the Kimberley Process but go beyond it by requiring an audited and transparent diamond supply chain.

Our tightly-controlled diamond supply chain also ensures we never sell any treated or synthetic diamonds. We double-check every single stone ourselves with the latest technologies available in our own office so we can guarantee that everything we sell is 100% natural. And, of course, buying direct from the source also means we can offer you excellent value without ever compromising on quality or cutting ethical corners.

Our Diamond Mine
We are partners in Lipari Mineraçao, which operates the largest diamond mine in South America, the Braúna mine in Brazil. We are proud to support the mine’s efforts to benefit its community and provide jobs, economic security, and productively reclaimed land for the people of Nordestina in Brazil. The mine is a showcase for responsible mining principles, so well run that it regularly opens its doors to the local community so that everyone can see first-hand how it operates.
The Beauty of Natural Diamonds

All the diamonds we sell are natural, ethically sourced diamonds with no enhancement or treatment of any kind other than cutting and polishing.

Diamonds that are made in a laboratory aren’t necessarily better for the environment because they consume large amounts of energy in the manufacturing process. They also provide much less employment than natural diamond mining and land reclamation. Our diamond sources always have their carbon footprint in mind when mining diamonds and believe wholeheartedly in land reclamation. For example, one of the ways they practice land reclamation is by planting trees to cover the area after mining is finished.

We’re hopeless romantics and love the miracle of a natural diamond: such breathtaking beauty, billions of years old from the fiery depths of the earth, unchanged by time. It seems such a fitting symbol of love.
