Faceted Ruby Semi-Spheres

Designed for beauty as well as function our semi-spheres add surface area and heat retention to any set up! All sizes fit in every insert we offer from 18mm-22mm, the Puffco Peak, Puffco Peak Pro, and they also work exceptionally well as a valve cover for Terp Slurper style nails. 

Experience next level dabbing with sapphire (and ruby) inserts!

When used as directed, our inserts last a lifetime - no replacements needed. Sapphire will never fog, crystallize, or "chazz" up and your gem insert will forever look the same as the day you bought it.

Unparalleled heat retention

Optimize your material for extended use, creating a more efficient sesh with less waste. Maximize savings with minimal waste - it's like putting money in the bank!

Exceptional durability

Unlike glass, sapphire is highly impact resistant. If dropped, your gem is guaranteed to never shatter.

Perfection is our goal

We maintain a strict tolerance level and prioritize quality control. Each insert is carefully inspected by our manufacturer, on arrival, and prior to shipping to guarantee superior product quality.
