Caesarstone Ltd. (Hebrew: אבן קיסר, Even Qeysar), is a publicly traded company that engages in the production and marketing of quartz surfaces used for kitchen countertops, vanity tops, flooring, wall cladding and general interior design.

Caesarstone Ltd. manufactures quartz surfaces in three different sites, two in Israel – Kibbutz Sdot Yam and the Bar Lev Industrial Zone near Karmiel, and in its new plant in Richmond Hill, GA, USA, since May 27, 2015 and sources products from third party facilities located in China.

Common uses of Caesarstone's products include quartz surfaces for kitchen countertops, vanity tops, wall-cladding, flooring and interior design of commercial spaces such as offices, restaurants, hotels, museums, and more.

The company was established in the wake of development work performed jointly by members of the kibbutz and additional parties such as Professor Moshe Narkis of the Technion.

After changing the focus from sale of floor tiles to quartz surfaces and establishing itself in the domestic market, the company started to export its products to different countries around the world.

In 2008, the company began establishing subsidiaries in its main markets: Australia (2008), Canada (2010), USA and Singapore (2011) and UK (2017) along with activity conducted through distributors in approximately 50 countries.

[23][24][25] In late October 2023, Caesarstone has launched an Australian ad campaign to oppose a ban on the product, which is linked to silicosis, a deadly lung disease.

Trade unions and politicians have condemned the ad as a “disgrace” and a “misinformation” campaign, and have compared Caesarstone to James Hardie, the company notorious for its asbestos liabilities.
