CBD Extracts: Shatter, Crystals, Moonrock and CBD Isolate

What CBD Extracts are and how they are made

CBD extracts are concentrated cannabinoid products derived from hemp, where the active compounds are extracted and refined into a denser format than the original flower. While a CBD flower typically carries 8% to 18% CBD across the inflorescence and the leaves, an extract concentrates the cannabinoid load into a smaller mass. That concentrate form can appear as a CBD shatter sheet at 99%, a CBD crystals isolate at 99.8%, or a moonrock-style flower coated in extract to increase the overall percentage.

The end product still comes from the same Cannabis sativa L. variety as our CBD flower catalogue, but the format and the concentration sit at the high end of the cannabinoid scale.

The extract category on Justbob runs across four product families: clear-glass-style shatter, crystalline isolate, cannabinoid-coated flower (moonrock and icerock), and high-CBD Boost extracts. Each one serves a different purpose. If you have already explored the flower catalogue and would like to try a denser format, the extracts are a natural next step. If you are new to CBD altogether, the standard flowers are the gentler starting point and the extracts can be considered later.

How extracts are made: from flower to concentrate

The extraction process starts with a flower or trim batch that has already passed our standard cultivation and curing protocol. The plant material goes through a CO2 supercritical extraction in an EU facility: a pressurised stream of carbon dioxide pulls the cannabinoids and terpenes out of the plant and deposits them into a separator.

From there, downstream steps split the output into different product families. A short purge produces shatters, a chromatography step yields the CBD crystals isolate, and a re-coating step over a flower base produces moonrock or icerock. The CO2 system leaves no butane, ethanol or propane behind, which is why the Justbob extracts read clean on residual solvent screen.

Why pick an extract over a flower

The reason customers order cbd extracts instead of flowers usually comes down to concentration. A small jar of cbd isolate at 99.8% carries more CBD than a much larger jar of standard flower, and the price-per-mg of cannabinoid drops accordingly once you do the maths.

Customers chasing a specific cannabinoid load find the extracts more efficient than the flower equivalent. There is also a textural element: shatter, crystals and moonrock present differently from a whole bud, and some shoppers choose them for the visual experience as much as the cannabinoid content.

Concentrated CBD with less plant matter, all kept under the EU-harmonised compliance threshold.

Our 8 CBD extract products in detail

The current selection on Justbob runs to eight cbd extracts products, grouped here into four families. Each one draws from the same selected EU hemp partners and the same lab-tested batches as the rest of the shop. Live prices and gram formats are listed on each product card.

SHATTER CBD LEMON, GORILLA and BLACK around 99%

The Justbob shatter line includes three variants, each around 99% CBD purity and named after the genetic backbone the extract derives from. SHATTER CBD LEMON has a citrus-leaning aromatic profile carried over from the Lemon-family terpenes. SHATTER CBD GORILLA features the earthier Gorilla profile and is one of our consistent best-sellers in the extract range. SHATTER CBD BLACK sits at the dark end of the shatter aromatic spectrum, with a denser visual appearance. All three present a near-isolate purity ,with a glass-like consistency that breaks cleanly into fragments. The CBD comes from certified Cannabis sativa L. extractions, and THC stays under the 0.3% EU harmonised threshold across every batch.

CBD CRYSTALS: 99.8% isolate purity

CBD CRYSTALS is the purest cbd isolate in the catalogue. The product is a crystalline cbd isolate at 99.8% CBD, isolated from biomass of Cannabis sativa L. through certified EU laboratory processes. Every other component of the plant has been removed: no terpenes, no minor cannabinoids, just CBD in a crystalline lattice. Customers who want a single-cannabinoid product, or who want to combine CBD with a different terpene profile than the original strain provides, choose the crystals over shatter or the moonrock variants. Cbd isolate as a category sits squarely on this product on Justbob: there is no separate isolate listing, the crystals are the isolate.

MOONROCK and ICEROCK: cannabinoid-coated flowers

MOONROCK and ICEROCK are the two cannabinoid-coated flower extracts in the catalogue. The base is a CBD flower; the coating is a layer of cannabinoid extract that significantly increases the overall CBD percentage beyond that of the flower alone. MOONROCK reaches up to 75% CBD, while ICEROCK can reach up to 90%. Visually, they maintain the shape of a flower, but feature a much denser, sparkling coating, created by a combination of the flower’s natural trichoms and the added cannabinoid resin. The result is a unique format that sits between traditional CBD flowers and highly concentrated extracts, which is why some customers choose them as a transition product when stepping up from the flower catalogue without going straight to a 99% shatter.

CRITICAL SUPER BOOST and OG SUPER BOOST extracts

CRITICAL SUPER BOOST and OG SUPER BOOST are the two Boost-line extracts cross-listed in this catalogue. CRITICAL SUPER BOOST is a glasshouse-grown product reaching up to 55% CBD content, with the Critical genetics behind the aromatic profile. OG SUPER BOOST is the indoor-grown counterpart, reaching up to 60% CBD, with the OG Kush family driving the earthy backbone. Both belong to our Boost Weed line, exclusive to Justbob since 2017-2018, in a high-CBD format that sits between a Boost flower and a refined CBD isolate. Customers who want a high cannabinoid load on something closer to a flower than a shatter end up here.

CBD shatter vs CBD crystals vs moonrock: understanding the differences

Picking between the four families depends on the format you want and the cannabinoid concentration you are looking for.

CBD shatter and CBD crystals sit at the high-purity end of the catalogue. The shatter is a glass-like sheet at around 99% purity; the crystals are the absolute 99.8% cbd isolate choice for customers who want a single-cannabinoid product without the carrier texture.

Moonrock and icerock combine flowers with extract layers and keep the visual presentation closer to a bud. The Boost extracts apply our cultivation protocol to the input material and sit in the middle, with a flower-like format and a denser cannabinoid load than a standard flower.

Across all four families, the cannabinoid percentages we publish on each product card are batch-specific, derived from the lab analysis of the most recent harvest. As plant-derived products, every batch may show minor variation, and the lab number is the authoritative figure: the percentage we list represents the upper end of the recent batch range. Whichever cbd extracts family fits you best, the live prices and lab data are displayed on each card at the top of this page.

How we extract from hemp to product

The Justbob extract production runs in EU facilities under documented, audited quality protocols. The hemp biomass goes through a CO2 supercritical extraction system, where pressurised carbon dioxide acts as a solvent to extract cannabinoids and terpenes from the plant material, with no butane, ethanol or propane residues in the workflow. Throughout the process, the CO2 is continuously recycled, helping to maintain a clean residual solvent profile while also reducing the environmental footprint of the production line.

From CO2 extraction to shatter, crystals and moonrock

Once the cannabinoid-rich oil leaves the extraction chamber, downstream processing splits it into the different extract families. A short purge under controlled vacuum gives the shatter sheets, where the consistency is shaped by the temperature and timing of the purge.

A chromatography step separates pure CBD from minor cannabinoids and produces the crystalline cbd isolate (CBD CRYSTALS at 99.8% purity). For the moonrock and icerock products, a separate step coats a CBD flower base with the extract under controlled conditions, then a fine kief layer is added to bind the coating.

Each step is documented and signed off, with the batch traceable from biomass to the final pack.

Hemp sourcing and EU cultivation network

The hemp behind every Justbob extract comes from selected EU growing partners. The varieties are registered in the European Common Catalogue under Regulation (EU) 2021/2115, the seeds are certified, and the cultivation method is documented from seed to seal. Indoor, greenhouse and outdoor protocols all feed the extract pipeline, with the cannabinoid load shaped by the cultivation environment. We don’t source hemp from non-EU producers: every extract batch is European hemp end-to-end, and the production happens in EU facilities.

Quality, lab tests and EU compliance

Every cbd extract batch follows an independent lab quality control workflow. Once a batch leaves the extraction facility, samples go to independent EU-certified laboratories for the cannabinoid profile (CBD, CBG, THC), the terpene composition where relevant, the residual solvent screen, and the heavy metal screen. Certificates of analysis are available on request: contact us at to info@justbob.shop with the batch code printed on the inner packaging and we will send you the lab report.

The non-negotiable standard for cbd extracts is the THC content, which remains below the 0.3% threshold harmonised across the European Union. The check happens daily on every batch that leaves our facility. The Court of Justice of the European Union confirmed in the Kanavape ruling of November 2020 that hemp-derived CBD products meeting this threshold can circulate freely within the European Union under the harmonised hemp framework. CBD extracts on Justbob are sold for technical, scientific, ornamental and collector purposes, in line with these requirements.
