Gemstone Cutting

Our cutting factory doesn't just meet international standards - it sets them. Columbia Gem House developed equipment and techniques to cut curved, concave facets to increase brilliance in colored gemstones. This technique, first pioneered by master cutter Richard Homer of the United States, uses facets like lenses to focus light back to the viewer's eye. It had never been tried before in a large volume production setting, and its success has now become our trademark within the gem-cutting industry.

Moreover, our factory is a model workplace; with wages that are three times the minimum wage, room & board, paid vacation, overtime pay, medical, disability and unemployment insurance, and annual bonuses. Our factory has nearly a zero rate of attrition, thereby increasing the skills of the craftsmen to the highest degree of experience in the industry. 


Columbia Gem House Contract Cutting Service


In certain circumstances Columbia Gem House provides reliable high quality faceting and cab cutting service to some of our customers. Our decision to offer our cutting services is made on a case by case basis, determined by the customer’s specific needs, volume and regularity of cutting. We normally avoid small volume one time or infrequent cutting runs because they are inefficient for our cutting operations.


If you are interested in having Columbia Gem House consider cutting your gemstones, please email with your specific needs including if you’re interested in faceting or cab cutting, types of stones for cutting and the volume of the rough you expect to send for cutting. Other information considered is whether the cutting will be repeated with any regularity, the sizes and shapes that are expected from cutting and any other information specific to your needs. The more information provided about your cutting requirements, the better we are able to determine if we can help with your cutting needs.


Provided that after reviewing all information, Columbia Gem House determines we are able to help with your cutting needs, we will send pricing as well as our overall terms and conditions for our cutting service.
