Is Diamond CBD Legit? A Public Records Check

In short: Diamond CBD is a real online seller. The address on its Better Business Bureau profile, 3531 Griffin Road, Fort Lauderdale, matches the address on a March 28, 2019 FDA and FTC warning letter to PotNetwork Holdings, Inc. Trustpilot showed a 4.0 score from 197 reviews when this page was opened on October 29, 2026. The potency certificates posted on product pages are real lab sheets, and several of them do not match the milligrams in the product title. This guide did not buy anything.

This page is for adults 21 and older. It is a records check, not a medical review and not a taste test. Purchase links go through the Hub's click log. The Diamond CBD buyer hub is the Minnesota-oriented catalog. A head-to-head with two other hemp sellers is in Diamond CBD vs cbdMD vs 3Chi. Evergreen checks that are not THC products: THC-free CBD oil, CBD dog treats, and THC-free sleep gummies.

How this page was checked

On October 29, 2026 the Hub read the FDA warning letter, the BBB business profile, the Trustpilot page for diamondcbd.com, Diamond CBD's lab-reports page, its FDA disclosure page, and its where-we-ship page. It also opened product pages and the certificate images those pages display. Nothing was ordered. No effect claim below is a Hub test. Where a product page uses wellness language, that language is identified as the seller's copy.

Seven records, and what each one says

Is Diamond CBD a real company?

The FDA letter is addressed to PotNetwork Holdings, Inc., attention Gary Blum, President, at 3531 Griffin Road, Fort Lauderdale, FL 33312. A copy line names Richard E. Goulding as CEO at the same address. The letter says FDA reviewed www.diamondcbd.com in September 2018 and found orders being taken for products claimed to contain CBD, including Liquid Gold Gummies and a blue CBD crystals isolate. Source: the letter linked above, read October 29, 2026.

The BBB profile read the same day lists Diamond CBD at 3531 Griffin Rd STE 100, Fort Lauderdale, FL 33312-5444, phone (305) 615-1194. Trustpilot's company block lists Griffin Road 3531, Fort Lauderdale, the same phone, and support@diamondcbd.com. Those three public records use one street address. This guide did not pull a current Florida corporate filing, so it does not say whether the 2019 parent name is still the legal owner.

The site's own where-we-ship page, read October 29, 2026, says consumable hemp products are federally legal and permitted to ship over state lines, and it defines hemp as cannabis with a delta-9 THC concentration of 0.3% or less by dry weight. That sentence is the seller's summary of the older federal line. It is not the text of the 2025 and 2026 amendments. Those dates are in the federal hemp changes guide.

Did the FDA warn Diamond CBD?

Yes. The March 28, 2019 letter is a joint FDA and FTC warning. FDA said website claims made certain CBD products drugs under the Federal Food, Drug, and Cosmetic Act because they were intended to cure, mitigate, treat, or prevent disease. The letter quotes pages titled "WHAT IS CBD?", "CBD in the Treatment of Cancer," and "CBD Shows Potential in Treating Alzheimer's Disease." It names epilepsy, autism, PTSD, diabetes, arthritis, and cancer among the claims FDA said it saw. FDA also said the cited products were not generally recognized as safe and effective for those uses, and that CBD was excluded from the dietary-supplement definition because it is the active ingredient in Epidiolex.

The FTC portion says it is unlawful to advertise that a product can prevent, treat, or cure human disease without competent and reliable scientific evidence. The letter asked for a written response within 15 working days. This guide did not find a closeout letter in the public letter itself. The letter is evidence of what the agencies said in 2019. It is not a finding about a 2026 product page.

The site footer read on October 29, 2026 says these statements have not been evaluated by the FDA and that the product is not intended to diagnose, treat, cure, or prevent any disease. That is the seller's current disclaimer. It does not erase the 2019 letter.

What customers report

The BBB profile, read October 29, 2026, says Diamond CBD is not accredited and carries a B rating. The rating reasons line says 19 complaints were filed against the business. The complaints page says 19 total complaints in the last 3 years and 8 complaints closed in the last 12 months. One listed complaint is dated February 4, 2026 and typed as a product issue, status answered. BBB customer reviews on the reviews page averaged 1.89 out of 5 from 19 reviews. Those are BBB's numbers, not a Hub survey.

Trustpilot's diamondcbd.com page, opened October 29, 2026, showed a TrustScore of 4.0 labeled Great, from 197 reviews. Trustpilot says it does not fact-check reviews. The company-written blurb on that page calls Diamond CBD a manufacturer of hemp-based CBD oils, vapes, edibles, gummies, and creams "with no THC." The live catalog the same day included delta-9 seltzers, THCA flower, delta-8 gummies, and THCP vapes. The blurb and the catalog do not say the same thing. Trustpilot reviews are opinions. This guide does not treat a star score as a lab result.

Are the lab reports real?

The lab-reports page exists at diamondcbd.com/lab-reports. Individual product pages display certificate images. The sheets this guide opened are Certificates of Analysis from Express Test Labs, 916 NW 6th Ave, Suite A, Fort Lauderdale, FL 33311. They name an analytical chemist, Dhruv P., a method of HPLC-VWD, and a signed date. They are not blank templates.

They are also narrower than the phrase "lab tested" often sounds. On the sheets read October 29, 2026, the icons for mycotoxins, residuals, terpenes, water activity, microbials, moisture, pesticides, and heavy metals say NOT TESTED. The test named on the sheet is potency. A green PASSED mark on those sheets is the potency result. It is not a pesticides or heavy-metals panel. The customer line reads "Order Center Co," not "Diamond CBD." The batch line often repeats the product name or is blank, so a shopper cannot match a future jar to that sheet by a lot code printed on the certificate.

One COA line, quoted

The 100 mg Berries THC seltzer page is titled 100 mg. The certificate image on that page, sample ID "100mg Nano D9 Seltzer Berries," analysis date January 2, 2026, lists delta-9 THC at 52.14 mg per unit and total cannabinoids at 103.30 mg per unit. CBD is 16.44 mg per unit, CBN 15.94, and CBG 18.78. Delta-9 THCA is not detected. Source: the certificate image linked from that product page, read October 29, 2026.

That is the concrete mismatch. A shopper who reads only the title sees 100 mg. The potency sheet's delta-9 line is about half of that. The total-cannabinoid line, 103.30 mg per unit, is close to 100. The page does not say which number the title means. This guide will not guess.

A second mismatch is on the 25 mg full spectrum CBD, THCV, and CBDV gummies. The product page lists 20 mg full spectrum CBD, 2 mg THCV, and 3 mg CBDV per gummy. The posted certificate, sample name "FS 20mg+CBDV 3mg+THCV 2mg," analysis date March 11, 2025, lists CBD at 10.68 mg per unit, THCV at 2.52 mg per unit, and CBDV at 3.12 mg per unit. Delta-9 THC is not detected. The THCV and CBDV lines are near the page. The CBD line is not 20 mg.

Does Diamond CBD use synthetic cannabinoids?

The catalog read on October 29, 2026 sells delta-8, THCP, THCA, and delta-9 products alongside CBD. The seller's Chill Plus brand page says delta-8 products are made from hemp. It does not, on the lines this guide read, print a conversion method. Whether a cannabinoid was synthesized outside the plant is a legal question under the new federal definition, not a fact this guide can see on a potency sheet. Delta-8 THC and THCP both appear as measured lines on Express Test Labs sheets for specific products. That shows the lab reported those cannabinoids in the sample. It does not show the manufacturing route. The is THCP synthetic page covers the November 12 and December 11 split.

Will a Diamond CBD product show up on a drug test?

This guide cannot answer that for a person. A potency sheet with delta-9 THC not detected is not a promise of a negative drug test. The berries seltzer sheet above reports 52.14 mg delta-9 THC per unit. The broad spectrum gummy sheet below reports delta-9 THC not detected and still reports other cannabinoids. The CBD and drug test guide is the page for how hemp THC and drug tests interact. It is not a Diamond-specific clearance.

What Minnesota shoppers should separate

Diamond CBD's site footer, read October 29, 2026, says: "We do not ship THCA products to the following states where THCA is restricted or illegal: Florida, Hawaii, Idaho, Minnesota, Oregon, Rhode Island, Utah, and Vermont." That is the seller's shipping rule. It is not a Minnesota statute. Licensed flower in Minnesota is a different aisle. Use the dispensary directory for adult-use and medical stores.

Minnesota's own hemp edible limits, read the same day on the Revisor of Statutes, are not the federal 0.4 mg line. Section 342.01, subdivision 50, includes a non-beverage path of no more than 5 milligrams of delta-9 THC per serving and a beverage path of no more than 10 milligrams of delta-9 THC in a single container. Section 342.62, subdivision 2, paragraph (f), says a package of multiple servings of a non-beverage lower-potency hemp edible must not contain more than 50 milligrams of delta-9 THC. A 100 mg or 200 mg seltzer is outside those beverage lines. A product that might sit closer is discussed in the best Diamond CBD products roundup, which is ranked from public pages only.

Adult-use cannabis in Minnesota also carries the state's cannabis excise tax. That structure is the subject of the Minnesota cannabis tax breakdown. A mail-order hemp order is not a dispensary purchase, and the labels do not use one math.

If you still want a product

If the certificate for the exact batch matches the label, and your state allows that product, Diamond CBD can be a place to shop. If the 2019 letter or the label gaps matter more, read the cbdMD review beside this one. cbdMD is a different seller, with its own pages and its own limits. This guide did not find a reason to call Diamond CBD fake. It also did not find a reason to treat a product title as the lab result.

FAQ

Is Diamond CBD a registered Fort Lauderdale business on the BBB site?

The BBB profile read on October 29, 2026 lists Diamond CBD at 3531 Griffin Rd STE 100, Fort Lauderdale, and says the business is not BBB accredited. The same street address is on the March 28, 2019 FDA letter to PotNetwork Holdings. This page does not include a separate Florida Division of Corporations printout.

What did the 2019 FDA letter accuse the diamondcbd.com site of doing?

FDA said claims on the site made named CBD products drugs because they were presented for disease treatment, including cancer and Alzheimer's pages quoted in the letter. The FTC portion questioned whether those advertising claims had the scientific support the FTC Act requires. The letter is dated March 28, 2019.

Do Diamond CBD certificates include pesticide and heavy-metal results?

Not on the Express Test Labs potency sheets opened October 29, 2026. Those icons are marked not tested. The reported test is potency by HPLC-VWD. A passed potency result is not a full safety panel.

Why does a 100 mg seltzer certificate show about 52 mg of delta-9 THC?

The berries nano seltzer certificate dated January 2, 2026 lists 52.14 mg delta-9 THC per unit and 103.30 mg total cannabinoids per unit. The product title says 100 mg. This guide reports both numbers and does not pick a silent definition for the title.

Does Diamond CBD ship THCA flower to Minnesota?

The site footer read October 29, 2026 says THCA products are not shipped to Minnesota, along with Florida, Hawaii, Idaho, Oregon, Rhode Island, Utah, and Vermont. Licensed Minnesota flower is listed in the flower guide, which is a different seller set.
