Precision Cutting

G.M.G. Sasportas’ reputation for accuracy and quality is based upon its decades of experience in the precision cutting of diamonds for fine watchmakers and jewelry designers whose expectations are only surpassed by our own.

According to Plan

All G.M.G. Sasportas custom-produced precision-cut stones are hand-manufactured in Israel, where customers’ technical plans dictate the cut and polish of stones – whether into matching stones, measured lines or atypical shapes, in all sizes. Precision cutting of baguettes is the company’s flagship service, which has earned the brand and its clients their reputations for outstanding quality.

Per Parcel

G.M.G. Sasportas also offers large-scale production of precision stones in standardized sizes between 0.01-0.70 carats, enabling customers to maintain inventory for production of larger volumes of product.



Actively involved in the process, from start to satisfaction…

G.M.G. Sasportas produces superior-quality precision diamonds from rough stones to the final polishing touches and project assignment.

The company is one of the largest manufacturers of Baguette-shape stones in Israel, responding rapidly to customer orders as they are received. In addition, its inventory of “Per Parcel” diamonds is produced outside the country at hand-picked manufacturing facilities, whose teams share the company’s standards for accuracy and elegance.

At all G.M.G. Sasportas production sites, diamond cutting and polishing experts operate the latest engineering software and manufacturing equipment available to produce an impressive collection of precisely sized and shaped stones, so accurate in their creation that they may be purchased in bulk and used with exacting precision on randomly-selected projects.

Each stage of the production process is subject to a rigorous quality control procedure to ensure that the precise weights, shapes and finishes for each stone are achieved.
