300mg Blackberry THC Seltzer - D8 & D9 Nano - Fresh
Crack the chill and let lush blackberry bubbles carry you into an easy, elevated groove.
Meet the Fresh Blackberry THC Seltzer, a crisp, sparkling drink crafted for clean flavor and a smooth, dialed-in experience. This refreshing blackberry seltzer blends nano-emulsified cannabinoids for fast onset and a consistently balanced vibe, powered by Delta 8 and Delta 9 with 300mg total cannabinoids.
- Delta 8 – Smooth, mellow relaxation that takes the edge off while keeping you clear, social, and in the moment.
- 100mg Delta 9 – Classic, mood-lifting euphoria with a bright, upbeat headspace to elevate any occasion.
The flavor lands bright and juicy—ripe blackberry up front with crisp bubbles and a lightly tart finish. It’s refreshing without heaviness, making it an easy sipper for after-work decompression, low-key hangs, or setting the tone before a night out. Thanks to nano-emulsification, the cannabinoids are finely dispersed for great consistency and a faster kick-in than traditional edibles or drinks, so you can find your flow and keep it there.
Whether you’re swapping out your usual beverage or leveling up your weekend lineup, this seltzer is built for smooth sailing and good company. Enjoy it chilled straight from the fridge or over ice when you want that extra sparkle—either way, the experience stays clean, balanced, and delicious.

Frequently Asked Questions
Is Delta 8 safe?
Yes! Delta 8 is entirely safe. While were still learning more about this novel cannabinoid every day, what we do know is that it is safe and that it causes a smooth but subtle high. (Its legal too!) Because delta 8 thc comes from hemp it will not harm you. Moreover, because Diamond sends all of our products through a rigorous third-party testing process, you can feel comfortable knowing you're using only the best delta-8 thc.
How long does Delta 8 stay in your system?
Delta 8 THC is very much like delta 9, or cannabis. Depending on how often you use it, and which type of product you use, it can be detected in your system anywhere from 5 days to upwards of thirty. One time users will be delta 8 free after about a week while frequent users will need 30-90 days for a clean drug test.
How does Delta 8 compare to Delta 10?
Delta 8 is more potent than delta 10 by a matter of degrees. Delta 8 THC is used by people who want to relax, while delta 10 thc is used by people looking for energy, focus, and creativity. Delta 10 will give you an awesome burst of energetic, explosive creativity unlike anything else in the hemp world.
