Offcanvas Section

You can publish whatever you want in the Offcanvas Section. It can be any module or particle.

By default, the available module positions are offcanvas-a and offcanvas-b but you can add as many module positions as you want from the Layout Manager.

You can also add the hidden-phone module class suffix to your modules so they do not appear in the Offcanvas Section when the site is loaded on a mobile device.

The biennial ICA Congresses are organized in member countries spanning the globe.

Many industry experts share their knowledge and insights with an audience of trade peers, industry professionals and ICA members.

Experience the ICA's Mining Tours to some of the world's most fascinating gemstone mines in member countries.

Networking is an important part of being a member of the ICA. The Congresses, trade shows, receptions and many other events are surrounded by social gatherings that foster business opportunities and professional relationships.

These events are an opportunity to gain broader and deeper knowledge, improve innovation, establish B2B partnerships and to advance careers.

Every two years, in coordination with our Congress, the ICA has an international poster competition. The winning design will be used for many communication and marketing efforts by the ICA worldwide to promote colored gemstones.

Participation in the competition has steadily increased over the years, accounting for more than 35 countries submitting designs with approximately 150 entries in total.
