How to buy wholesale at Tucson, Denver and Quartzsite

The big buying season runs from January into February in Arizona, at Quartzsite and then Tucson, with a second season in Denver in September. For 2027 the show-guide publisher Xpo Press lists Tucson shows running from January 4 to February 20 [1], Quartzsite's main rock and gem shows in January and February [2], and Denver's showcase in September [3]. Some shows sell only to the trade, and the guide advises having "a resale license" ready for them [3]. This page gives the 2027 dates as published, explains wholesale-only shows and what to bring, and covers budgets, minimums, checking stock and getting it home.

The 2027 calendar

Dates below are as Xpo Press listed them when read on October 22, 2026. Shows change dates and venues; confirm with each show before you book travel.

Tucson (late January to mid February)

Tucson is dozens of shows at once, spread across hotels, tents, warehouses and the convention center. Xpo Press lists 2027 Tucson-area shows starting as early as January 4 and ending as late as February 20 [1]. A selection, chosen to show the range:

Sources do not always agree on dates. The events site Tradefest lists the G&LW show as January 28 to February 5, 2027 [4], a day shorter than Xpo Press's listing. Check the organizer's own site, which Tradefest gives as glwshows.com [4].

The Tucson Gem and Mineral Society's own show, held at the Tucson Convention Center with retail dealers in the Exhibition Hall and Ballroom, had not posted 2027 dates when its site was read; it said "Updated information coming soon" [5].

Quartzsite (January and February)

Xpo Press does not say which Quartzsite shows are wholesale or retail [2].

Denver (September)

Xpo Press describes the 2026 Denver Gem and Mineral Fall Showcase as 11 shows from September 7 to 20, 2026, and for 2027 lists the Denver Expo Gem Show for September 9 to 19, with other shows' dates still to be confirmed [3]. It names three Denver shows as wholesale-only: the JK Stone show, the Colorado Independent Warehouse Show and InterGem [3].

Wholesale-only shows and what to bring

Some shows and dealers sell only to businesses buying for resale. They want evidence that you are one, and the usual evidence is your sales tax registration. Xpo Press advises having a resale license ready for Denver's wholesale-only shows [3], and links to a separate Tucson admission requirements page from its Tucson listing [1]. Requirements differ by show and change, so check each one before you go.

Bring:

• Your sales tax permit or resale certificate, in your business name. A seller's permit "lets you buy wholesale inventory without paying sales tax," as one vendor puts it [6]. Whether an out-of-state resale certificate is accepted, and what Arizona or Colorado require of buyers and sellers at shows, are covered on sales tax, resale certificates and show permits.
• Business cards with the same name.
• Photo ID.
• A way to pay that the dealer accepts; ask ahead for large purchases.
• Your stock list, so you do not buy what you already have too much of.
• A loupe, a small flashlight and a magnet for checking stock; see the next section.

Budgets and minimums

Wholesale dealers often set minimum orders. One vendor's 2026 article says wholesalers typically set "$500 to $1,000" minimums [6]; that is their estimate, and individual dealers vary widely. Plan the budget before you arrive:

1. Decide what you need from your sales records: which stones sold, at what price, in what sizes.
2. Set a total budget and a per-dealer limit.
3. Price backward. If you price on cost, you need to know your retail price before you agree a wholesale price. The method, and channel fees, are on what to charge.
4. Hold back a reserve for the find you did not expect.
5. Count shipping in the cost of every lot.

Checking stock before you pay

Show floors are where dyed, coated and imitation material moves in quantity. Before you buy a lot:

• Ask the dealer directly whether the material is treated, dyed, coated, heated, stabilized or reconstituted, and get the answer on the invoice. One vendor notes that "Reputable wholesalers disclose heat treatment, irradiation, and dye jobs in writing" [6].
• Look at a sample under a loupe for dye concentrated in cracks, coating wear on edges, or bubbles in "natural" glass. What to look for, stone by stone, is on dyed, heated, coated and lab-grown stones.
• Ask where it came from. Country of origin for imports; locality and land status for U.S. material. Material collected under a hobby allowance on federal land cannot be sold (43 CFR 8365.1-5(c) [7]); a dealer who cannot say where U.S. material came from is a risk. The records to keep are on what makes stock lawful.
• Watch for fossils and artifacts in mixed lots. Their sale is restricted; see can you sell fossils? and arrowheads and other artifacts.
• Get an itemized invoice with the dealer's name and contact details, the stone, the origin, any treatment, the quantity and the price.

Getting purchases home

Arizona in February and Denver in September are kind to specimens; a parked car is not. Do not leave specimens in a closed car in the sun, since heat and temperature swings can crack crystals; see heat and thermal shock.

• Ship heavy lots rather than carrying them. Ask each dealer whether they ship, at what cost, and with what insurance.
• Pack fragile pieces yourself if you carry them, wrapped individually; the method is on packing and shipping specimens.
• Keep invoices with the lots, and photograph each lot as you pack it.
• Unpack and rehouse on arrival. Wholesale packing is not storage; see keeping stock in sellable condition.

Choosing who to buy from

The show calendar tells you when to go; the harder question is which dealers to trust with your budget. How to check a supplier, the written disclosures to ask for and the origin and labor questions buyers raise are on who to buy from.
