Cutting models with a laser has big advantages on making it with a worker.
With the lasers help we cut all the models that exist in the market, like: Hearts, Emerald, Hexagon, Oval, Pears, Marquise, Stars of David, Stars, Trapez, Triangle, Square and more…..

Cutting with a laser enables you to build the stone by the customer’s needs, with the help of the advanced optical system, defects in the diamond can be spotted, (for example Gletz, Pikes, bubbles) and then we can mark the wanted model of the stone while neutralizing the problems.

In all the new laser systems you can see the diamond on a LCD screen on the system’s computer, in a huge resolution, and in that way you can set the stones model with a micron precision on the diamond surface.

Thanks to the high precision and the perfect symmetry, of the computer system, you can get to maximum exploitation of the diamond and creating a perfect model, a fact that allows us low and minimal loss percentage.

Of course that the computer systems offer you the option, to create perfect couples with a micron precision and as well a whole set of identical stones in its structure, arches, length and width.

As well, it is possible to cut a big amount of stones in less time, while keeping the security of the diamond.

Cutting models can be done on Raf stones, on opened stones, and also on polished stones that the customer wants to change its models, or to fit it for pairs.

The laser saws in a micron precision, while keeping low and minimal loss percentage, the sawing is done smoothly through the whole sawing surface.

Each stone that gets to the factory goes through a check up with a professional Polarization tool, which was specially imported from Germany, The Polarization tool gives us important information, if the stone has unexplained pressure inside,we can see where is the pressure with the human eye, and in this way it permits us to decide decisions, which will keep the structure of the diamond and will prevent damages to the diamond.

The company’s laser services have unique protections, which avoid damage to the stone during its manufacture.

The size of the hole or dimple can be set with a micron precision.

These holes and dimples are used to fit diamonds in a peace of jewelry, or combining diamonds with each other.

The sawing of the hole can be done in polished stones or Raf stones.

NesCut Lasers – Complex Diamond Models with Maximum Accuracy and Safety

By Rachel Lieberman

Nessi Shimony is a second-generation diamantaire. His father, Amos, is a veteran member of the Israeli Diamond Industry who handed the management of the company’s manufacturing department over to his son. About a year and a half ago, Nessi opened the company’s laser department.
Why a laser department? When Nessi, a computer engineer by profession, first set out to manufacture complex diamond models, he noticed that there was a dire need in the industry for such intricate and meticulous work. As someone who learned all about diamonds on his father’s knee and is well acquainted with all of the stages of diamond polishing, he decided to specialize in laser. Armed with all of this knowledge, as well as extensive technological skills, he built two unique laser systems specifically for sawing highly complex models.

“In addition to my training as a computer engineer, I am also a certified diamond setter and a graphic artist. Thanks to my comprehensive vision, from the beginning of the manufacturing process up to the actual setting, I am able to advise clients on the most profitable way to cut their diamonds. Through the use of the sophisticated technology that I developed, I help diamond manufacturers and jewelers to construct complex models with the utmost accuracy.”

Nessi describes the process: “The jewelry item’s planning is based on special graphic and design software. With this software it is possible to build a mosaic of diamonds for mounting in the jewelry piece. I meticulously cut the diamond model, which is composed of precise angles and arcs that complement each other in the mosaic. The stone can be cut in its rough or polished form. In addition, the stones can be cut in pairs or as highly accurate series.”

Nessi works mainly with diamond manufacturers, watch manufacturers and local jewelers, and just recently sent his first project overseas. He intends to expand his business abroad.

Some companies hesitate to go into complex models due to the high costs of developing models and adapting them to laser systems. Nessi stresses: “I handle the development of the models and their adaptation to the laser system absolutely free of cost.”

In addition to its specialization in complex models, the company also offers standard laser services in the industry such as laser sawing, holes, depressions, cleaving and marking.

Nessi summarizes: “My company is very dynamic. I can state with great satisfaction that to date I have always been able to meet all of my customers’ diverse specifications in the area of laser with great success, and I promise there is much more to come…”
