The Tevinskoye agate deposit is located on the eastern coast of the Shelekhov Bay of the Sea of Okhotsk, 120 km northeast of the Palana village in the western part of the Kamchatka Peninsula.

The deposit is represented by a series of agate-bearing fields associated with the Eocene volcanic rocks of the Kinkilsk complex.

The agate deposits referred to in Svetova et.al. are near the mouths of both the Mainkaptal and Eltavayam rivers that flow into the Seaa of Okhotsk..

Coordinates are for the approximate centre of these two agate localities.
