Diamond cutting as an art form goes back as far as the 14th century, but the first true diamond faceting technique was developed in the 16th century with the development of the Rose Cut.
In the early 18th century, diamonds saw an increase in popularity and production mostly out of Brazilian mines. The Old Mine Cut was developed in this time period and maintained it's popularity all the way through the late 19th century when industrialization really started to impact the diamond cutting industry.
In the mid to late 19th century, diamond cutting truly became a modern industry. There was a diamond rush into various regions of Africa and diamonds saw an unprecedented surge in popularity. With this industrial age of precision and steam machines came the 58 facet European Cut. This cut included a round girdle (which gives it the round top view) and rather than coming to a point, the European Cut was cut flat on the bottom, which is called an open culet.
Over time, the European cut evolved and slowly became more "ideal" until it became what we know today as the standard Brilliant Round Cut in 1947. They essentially just improved upon, some would say "perfected," the old design until it was the best that it could be. Unfortunately, the cut design itself doesn't truly reveal how much a diamond could sparkle and catch the eye. That's why in 2017, 70 years later...
The Jocelyn Diamond is the next great evolution in diamond cutting. A Jocelyn Diamond stands out in a crowd because of it's precisely cut faceting that gives the fire of the diamond new life.
The Jocelyn cut was born out of decades of jewelry and lapidary knowledge. Master craftsman from all corners of the world have pooled their wisdom into releasing the true potential that laid dormant in diamonds for so long.
