Sapphire is dried sieved cannabis also known as “kief”, referring to the granular/powdery accumulation of trichome heads, which are the resin glands where cannabinoids and terpenes live. It’s the dry sift process that separates the trichome heads from the plant, minimizing the amount of plant material in the end product. Kief has many different uses – you can sprinkle it onto your bowl, add it to your joint, cook with it, press it into hash or heat press it into rosin.
