Pure CBD Crystals: 500mg

Discover one of the key ingredients behind our success!

CBD is a compound found and extracted from specific hemp strains. Contrary to THC, it has no psychotropic or hallucinogenic effects. Harmony CBD Crystals are the purest CBD extract you will find.

From Hemp to CBD

After hemp oil is removed from the plant, it can be further refined to isolate only CBD. To isolate our pure CBD crystals, we extract hemp oil to put it through a ‘winterisation’ process or slowly heated to remove fats and lipids. Then, we use a machine called a rotary evaporator to remove any remaining plant traces. The final product is decarboxylated through another meticulous heating process to activate the cannabinoids, making them bio available for consumers.

CBD extraction from hemp

How to use the CBD crystals:

CBD crystals give consumers more versatility than oil. Like hemp oil, you can add them to food, dissolved in drinks or swallow them whole. But unlike oil, crystals can also be ‘dabbed’  like cannabis concentrates (a manual vaporization method) made into an E-liquid, or sprinkled over a cigarette or joint.

    Hi! I would like to know if this cristal are like critalized or dust.. I’m asking that because i wanted it to make some ejuice with it but i need know better the product before i get in to it. My question is if i dissolve it in 20ml of ejuice would it have a ratio of 250mg/ml or if i put it in 10ml i will get the straight 500mg/ml since its the quantity of cbd in this product. I would be glad if you could help! ty

    • Clara

      Hello Andre! Thank you for the interesting question 🙂 Our Pure CBD crystals are crystallised as they are sold in the purest form possible.
      Concerning the dosage, you are actually totally right! By dissolving 500mg of Pure CBD Crystals in 20ml e-liquids you will have a ratio of 25mg/ml or 2.5% CBD. On the other hand, if you get straight 500mg Pure CBD Crystals in 10ml e-liquid bottle, the ratio goes up the 50mg/ml or a ratio of 5% CBD! Let us know if we can help you more! Have a wonderful day!

    can your Pure CBD crystals be added to liquid to consume/ingest?

    • Clara

      Hello Homey, thank you for your interest 🙂 CBD crystals have a broad spectrum of uses as mixing with a carrier oil or baking for ingestion. it is important to remember that CBD is not water soluble and therefore, it all starts with the butter! Have a great day!

    This product is amazing. I havent much experience with other vendors but Im amazed on how it works. It wont get you high (havent tried high dosages).

    How I used it:
    1x 500mg in 30ml of my own juice (so it was 16.6mg/ml) And it worked since day one, as I have fallen asleep after some vaping. The following days wasnt that way though, I was 100% anxiety free while in public and vaping it.

    And another way I tried:
    I though I could potentiate the cbd of my hemp buds. What I did was:
    Dissolve 1x 500mg in 10ml (50mg/ml) in preheated(for faster dissolving) PEG400 (not PG) and then sprayed over my EU-legal(<0.2thc) hemp buds. Worked as expected (actually better – THOUGH I DONT RECOMMEND THIS METHOD before someone from the harmony team approves it).

    My next order Im planning will be for 3 grams of this (2x 3packs, maybe more) and will use the last method I mentioned.

    Btw, thanks for the gift and the lolipop <3

    Very nice option to have, with these crystals you can fill your eliquid with more CBD for a stronger effect or mix em with your own eliquid

    How much E liquid can I make with 500mg of cbd?

    • Clara

      Hello Jamie! Thank you for your interesting question 🙂 It is hard to give an accurate answer since it will all depend on what CBD concentration you wish in your e-liquid and what’s the e-liquid countenance. As a reference, if you put the whole Pure CBD base (500mg) in a 10ml e-liquid you will obtain a CBD e-liquids with 5% CBD. If you put 250mg in two 10 ml e-liquids you will obtain 2 CBD e-liquids with 2.5% CBD and so on…Hope it will help you 🙂 Have a great day

    What is the recommended concentration prescription for cbd eliquid ? If i make a 5% concentrade CBD liquids do i have to put some drops in my favourite eliquid or i’ll have to take it directly ?
    thank you for answering ! 🙂

    • Clara

      Hello Kessas! Thank you for your message! The good CBD dosage is hard to determine since it deeply varies from person to person. When trying to determine the correct amount of CBD dosage you need it’s best to start small. With CBD, you can easily scale up just a few milligrams at a time to meet your personal needs. Harmony Pure Base only contain CBD and PG therefor you need to mix with your favourite e-liquids to be able to vape it! If you make your own CBD e-liquids and if it contains PG AND VG then you will be able to vape it directly 🙂 Let me know if it is clear to you! Have an amazing day!

    I seriously think meetharmony is the best supplier of all CBD products on the market. I’ve tried so many different oils, concentrates, edibles, etc and nothing leaves me more satisfied than just using the Super Lemon Haze vape oil, and sometimes I add some of these CBD crystals to it to help me sleep! I use CBD every day and am so glad to have found this company to guide me to where I need to be to be who I need to be! You’ve literally changed my life in so many ways so all I can say is… THANK YOU SO MUCH!!!!

    • Clara

      Hello Ash! Thanks a lot for your amazing feedback, we seriously think you are one of our best users 😀 We sent you a little surprise on your emailbox to thank you for your kindness! Have an amazing day!

    hello, i d like to know if i can mixed the crytal with some CBD oil like the Mango kush or any other ?

    • Clara

      Hello Sebatien! Thank you for your message! Indeed, it is totally possible to add Harmony CBD Crystals to Harmony Super Lemon Haze e-liquid for a higher CBD ratio 🙂 Just make sure to shake well and wait a bit that the CBD crystals are well dissolved before vaping!Hav a great day!

    Is it legal in every country? I know it doesn’t have THC in it, but I ask this, since it’s made out of actual cannabis.

    • Clara

      Hello Barry! Thank you for your message! CBD is not legal in every country. Each country applies its own specific legislation about CBD products. We can ship Harmony’s product in most of the countries as we are extracted Harmony’s CBD from Hemp and there is no trace of THC 🙂 If you have any further question, please don’t hesitate to ask! Have a great day

    Frist of all CBD crystals never dissolves directly into pg/VG mixture. Some thread says heat the PG and dissolves your crystals then add flavor and then your VG. I tried this method and got crystallization. So I been searching right way to mix cbd crystals in VG/PG but can not find the right thread. Flavor is another issue. Some people say use oil-based flavor only. So Is that true? The regular flavor which we use for nicotine base eliquid doesn’t work?
    Any explanation will be appreciated!

    • Clara

      Hello Rick! Thank you for your message! Making your own CBD-based e-liquid is just like baking cupcakes. You need the basic ingredients (CBD, PG and VG) and add the flavour to your taste. Indeed you shouldn’t mix CBD directly into PG/VG but first mix CBD with PG to then add VG. We recommend that you use a relatively low amount of VG (30% max) to ensure the solubility of CBD in the blend. Then add the flavour, starting with low amount and increment to reach the level that suits you. You can use concentrates or premixes (again, with low VG content). On another side, you can also use nicotine base to make your e-liquid that won’t altered the CBD. We hope it helps and wish you an enjoyable vaping experience!

    I need to know the weight of the jar that contains the crystal so I can weight it without taking the crystals off. Thank you in advance.

      Hello Paloma! The weight of the jar that contains the crystals is 5.70g 🙂 Let us know if you have any other question. Have an amazing day!

    Which Harmony CBD can i Vape direct & Which Harmony CBD did i have to mix with my e juice

    • Clara

      Hello Mike! Thank you for your message! All Harmony CBD e-liquids Classics (Hemp, Strawberry, Mint) and Originals ( OG Kush, Super Lemon Haze, Mango Kush) are ready to be vape! Only Harmony Pure CBD Base need to be mixed with another e-liquids as it only contains PG and CBD 🙂 Don’t hesitate to ask if you have any further question! Have a great day

    Love the crystals on my night tea before going to sleep! If I’ve had a very stressful day I might as well just do sublingual and crash on my bed. great product, and beautifully packed!

    • Clara

      Hello Lucas! Hopefully, stressful days are scarce and CBD flows in abundance! Thank you for your good words <3

    i used this but found i got recrystallization mixing at 50vg/50pg, is there a way to thicken my juice without having to use vg as vg seems to be the problem. i mixed at a higher pg ratio but its too throaty and too watery. any help would be greatly appreciated as i rate this product highly.

    • Clara

      Hello! Thank you for your message and good words! The recrystallization of your base is due to the fact that CBD doesn’t dissolve in VG that is too thick. We recommend that you use a relatively low amount of VG (30% max) to ensure the solubility of CBD in the blend. You can first mix Harmony CBD Crystals with PG, then wait a few hours to make sure it dissolved well to then add VG. You can see the whole process here. We hope it helps and we wish you an enjoyable vaping experience 🙂

    Hello! i buy and is excellent product for vaping, but i have a question: it’s possible take under tongue only the crystals?

    • Clara

      Hello Emiliano! Thank you for your good words – much appreciated 🙂 We don’t recommend the sublingual use of Harmony CBD Crystals. What you could do is to mix the Pure CBD Crystals with a small amount of carrier oil that you can drop directly into your mouth or eat with a small piece of bread! Don’t hesitate to ask if you have any further question! Have a great day!

  19. Rated 5 out of 5


    and mix with which oil? olive no? 🙂

    • Clara

      Hello Emiliano! You can mix Harmony CBD Crystals with the carrier oil you prefer! It could be olive oil but also coconut oil or hemp seed oil for example 😀

    Nathan Scott

    HI, I love this product!

    Can this product be added directly to the 0mg CBD OG Kush Terpines?
    As this is 10ml 80/20 pg/vg, therefore 50mg added to 10ml would yield 5%?


    • Clara

      Hello Nathan! Thank you for your nice words! ​I have a great news for you, you can indeed add Harmony Pure CBD Crystals direclty into Harmony OG Kush – 0mg. 50mg of CBD added into 10ml base will give a concentration of 5mg/mL or 0.5%. You will yield a 5% CBD concentration by adding 500mg CBD into a 10ml base or the full Harmony Pure CBD jar 🙂 If you have any further question, please don’t hesitate to ask! Have a great day

    I have a question about the CBD Cristal… how do you mix with drinks ?? example Tea? ..how much for a Teacup? and when is about cold drinks? and for how long I can save this?

    • Clara

      Hello Cesar! Thank you for your message! When it comes to mixing Harmony Pure CBD crystals into drinks, the most important to remember is that CBD is non-water soluble and therefore always need to be mix with some kind of fat ( milk, coconut oil..). Watch our video “How To Make Delicious CBD Hemp Tea” explaining the simple steps for the best hemp tea 😀 This main rule also apply to cold drinks that can be saved up to 2 weeks when opened!

    Absolutely worth the purchase. I read a lot of CBD products good, so I decided to order and make this vape fluid. I made a 30ml liquid and put 500mg of CBD crystal into 16.6mg / ml. The problem was that the crystals did not melt into the finished liquid, but 60 degrees Celsius under water under the bottle, and with stirring the crystals melt. At my point I use 2ml of fluid throughout the day, keeping the breath 10 to 15 seconds. This fluid works very well, a couple times when I take it i start feeling calm and stress free myself, and other things in mind go away so I can continue my studies or my normal life in peace. I will buy more in the future, but I have to think a bit about how much I can put money as a student because my income is limited. Good to know that the substance works for me! I rate this product 5/5 and buy more future.

    Sry bad english 🙂

    • Clara

      Hello Pruuno! Thank you so much for your good words and for sharing your great experience! One of the reasons why the crystals didn’t melt might be a high VG e-liquid ratio. As a trick, you can note that CBD doesn’t dissolve in VG and therefore always need to be mixed with PG first.
