Tips for Searching the Site

The large green search field at the top of every page can be used to find products by full name, partial name, brand name or 7-digit item number (with or without the dash). This search returns results in Product Categories, Brands and individual products by name and it displays its results with images and price ranges.

If you know Gesswein's 7-digit item number, use the "QUICK ORDER" form on the homepage. Type in your item number (with or without a dash) and a quantity and press "Add to Cart" (or just hit the enter button on your keyboard). The item's full name will display in your cart as a link to the page it's on. Just press the "Checkout Now" button to order quickly and easily.

The A-Z Index at the top of the page allows you to search by full or partial product name and brand name. It returns results in product categories and brands.

The Product navigation bar at the left side of every page is a convenient way to browse through product categories. Select the "BRANDS" tab at the top and you can browse through all the famous brands names Gesswein carries.

International Shipments
We ship via UPS and Fed Ex International. We will contact you upon receipt of your order to discuss shipment and delivery options. At the same time we will advise if there is a more economical method of shipment.

Out of Stock Items
Most of the products we sell are in stock at all times. However sometimes a backorder situation can occur. If any item on your order is out of stock, you will be notified by email or phone. Please make sure your contact information is up to date. (To update your info, go to "My Account" at the top of the page.)

If overnight delivery is urgent, please phone in your order: 1-800-243-4466 or 203-366-5400, Monday through Friday, 8:30 am to 3:00 pm EST.

Hazardous Shipping Fees
All carriers charge a hazardous shipping fee for items they identify as hazardous such as flammable liquids, acids, some plating solutions, etc. The fee is usually $27.50 in the USA, more for international shipments. Often there is a separate fee applied to each hazardous item in the shipment. This fee is indicated on the page for any product to which it applies and will automatically be added to your cart as a separate fee at time of purchase.

UPS and FedEX regulations restrict our hazardous items to ground transport only. Both carriers limit the quantity and type of hazardous items that may be shipped in one carton. Most trucking firms charge per shipment. USPS (US Mail) does not accept hazardous items. Internationally, hazardous items can be shipped via air freight or ocean freight only. DHL does not accept hazardous shipments.

If we feel that your order has an undue amount of hazardous shipping charges, we will contact you to suggest more economical shipping options.

Both UPS and Fed Ex permit only authorized hazardous goods shippers to ship hazardous items. They will not permit returns of hazardous items by anyone who is not an authorized hazardous goods shipper.

Common Carrier (Truck) Shipments
Some items, due to their size or weight, must be shipped by common carrier/truck. This information appears on the product page. These shipments require a separate shipping charge which will not be charged to your card until we have contacted you with a quote and received your approval. We have negotiated lower rates with selected carriers and will choose the most economical carrier for your shipment. We will contact you prior to shipment to arrange delivery.

If the trucker will have to off-load your shipment to a smaller delivery truck (i.e. limited access to your door – narrow alleyway) there may be a delay in delivery. Please make us aware of any special needs so we can take steps to minimize such delays for you.

We will telephone you the day the shipment is picked up at our facility in Bridgeport CT and provide you with the PRO (tracking) number and estimated delivery date.

Truck Shipment Charges – in addition to the Freight Charge
The following services can generate extra charges above the normal trucking rates:

Residential delivery
Liftgate service
Inside delivery
Hazardous goods surcharge
Redelivery due to customer unavailability
Telephone call notification by trucker prior to delivery
Any changes to the shipment after pick up from FOB point

Charges & Fees
Our UPS and Fed Ex shipping charges include an insurance fee for protection against loss and damages during transport. If your package or item is damaged, please refer to the "Shipping Damage" section of this guide.

If you have a Gesswein open account and you choose to charge freight to your own UPS or Fed Ex account number, the shipping fee charged to your account by UPS or FedEx may vary slightly from what is shown on our site and on the receipt generated by the site. Please use the shipping charge shown on the site as an estimate only.

Sales Tax
For domestic (USA) sales, we are required by law to collect state sales tax for certain states. If you have a valid sales tax resale-number and/or tax exempt number, you may not have to pay state sales taxes. Please fax your Sales Tax Exemption form to Gesswein at 1-203-366-3953.

Return Policy
If for any reason you wish to return merchandise, use the Return Form on your packing slip. All returns must be shipped prepaid, be in unused condition and in the original packaging. Be sure to package your return properly to avoid shipping damage, insure it, and use a carrier with tracking capability; we suggest UPS or Fed Ex. If you choose USPS please ship by Express Mail which includes tracking.

We do not accept collect or COD shipments.
We reserve the right to charge a restocking fee for catalogued items returned after 30 days.
Non-stock items ordered specially for you are subject to a restocking fee.
Items made to your specifications are not returnable.
Returns will be credited in the same manner as they were paid.
Hazardous items can be returned only by authorized hazardous goods shippers.

If you require assistance, please call one of our friendly Customer Service Associates at 1-800-544-2043 or 203-366-5400, Monday through Friday, 9:00 am to 5:00 pm EST. Please have your packing slip and/or invoice at hand.

Shipping Damage
If you see any obvious damage to the outside of the package (such as a hole, ripped or damaged cardboard, crushed corner — even if the damage appears slight), point it out to the carrier and write "Damaged" on the carrier's delivery sheet next to your signature. Do not sign the delivery sheet without a notation about the damages. If upon opening the box, you find the item(s) are damaged, please call us at 1-800-544-2043 or 203-366-5400 or email us at custserv@gesswein.com so that we may assist you in both getting a replacement quickly and arranging for return/pickup of the damaged item. Be sure to save all cartons and packing materials.

If the box appears to be in good condition but you discover that the item inside is damaged, you should promptly contact Gesswein or the carrier. (This is classified as "hidden damage" and can occur when a box is dropped but lands flat causing no visible damage to the box itself.) Save all shipping cartons and packing materials for inspection.

Gesswein will not assume any responsibility for any losses that occur due to your failure to follow these steps.

ISO Ring Size Standard 8653

1. Scope and Field of Application
This International Standard specifies the method for measuring the size of rings for the purposes of designating ring-sizes to be used in jewelry.

2. Definition
Ring-size: The inner circumference of the ring expressed in millimeters.

3. Measurement
The inner circumference of the ring should be measured using a tapered ring-gauge (ring-stick) with the following characteristics:

a) length of the measurement scale: 160 ± 0.5 mm

b) minimum ring-size: 41

c) maximum ring-size: 76

d) material: metal, or material with equivalent wear resistance.

4. Designation
The size of the ring shall be designated by the number of this International Standard followed by the inner circumference of the ring expressed in millimeters rounded to the nearest millimeter. Example: Designation for a ring with a ring-size of 43mm measured in accordance with this International Standard : Ring-size IS0 8653 - 43
