Sending Stones to Lambert

Rough stones can be packaged in plastic bags and placed in a small box or padded envelope. Be sure to enclose

(1) a packing list (if you don’t know what kind of gemstone will appear from your rough stones, that’s OK)
(2) any cutting specifications or special instructions, and
(3) either an email address or telephone number where you can be contacted if we have questions.

Lambert has no minimum order size, and we suggest that you send more rather than less if you are unsure if your rough stones can be cut.

Most of the rough stones that Lambert receives are sent by regular registered mail (for example, Australia Post, Canada Post, or the United States Postal Service) requiring a signature. FedEx and DHL are quite expensive and will charge all taxes back to the sender for incoming packages; therefore, we do not suggest these methods.

When shipping rough stones, clearly label the package “Mineral sample, no commercial value” (remember, most rough stones have little or no commercial value—you are not estimating how much the cut gemstones may be worth on the customs form, only the value of the actual rough stones). However, if you choose to insure your package for the assumed value of the cut gemstones, be sure that the value is not on the outside of the package or the Government of Thailand will charge a 30% incoming duty on this written value. Lambert will add this to your bill and contact you if this charge is over US$50.00. If you must put a value on the outside of the package as required by some countries, Lambert suggests a nominal value of US$25.00.

Lambert uses Thailand Post for returning cut gemstones. They are shipped by registered insured airmail with a signature required. In our experience, it is an extremely rare event for a parcel to go missing. Our return postage charge is US$19.00, and express mail is US$65.00.

Unsolicited praise for our gem cutting service says it better than we can: “The size and shape of each stone had determined the final cut…” “There was no way, as a novice, I could have executed such a wide variety of cuts or even worked with the small sizes of some of the stones.

“So how did they look? Well, to put it simply, they looked great. I even had one piece returned that was deemed unsuitable for cutting. I was also impressed with the professional invoice that came with my gemstones…” “I figured I saved myself about $400 (Australian) by getting them cut in Thailand.” “So, to all of you who thought the Lambert Industries classified advert urging you to get your stones cut in Thailand was too good to be true, your wrong.”
