Tec-9 | Red Quartz is a Restricted-tier pistol finish, part of The Train Collection and dropped from the DreamHack 2013 Souvenir Package.

The float range for this finish is restricted to 0.00–0.40, so Factory New, Minimal Wear, Field-Tested, and Well-Worn are the only obtainable conditions on the open market. Battle-Scarred examples are not produced, so the most worn copies still retain a relatively clean appearance.

A Souvenir version is available, dropped exclusively from cases collected during Major Championship matches and stamped with that tournament's stickers. Active listings for Tec-9 | Red Quartz are tracked across 18 marketplaces, with prices spanning $0.29 to $249.98 depending on wear, variant, and seller.
