| Customers ordering multiple items will pay full shipping on the item with the highest posted rate in their order, and will receive $2.95 off the posted shipping rate for each additional item (which works out to $1.00 S/H for additional items with a $3.95 shipping rate). S/H cost is a flat rate to CANADA and USA. We will combine purchases for a period of 14 days however to qualify for combined S/H discounts ALL items must be paid for within the same invoice. Further S/H discounts will apply to large volume purchases. S/H is usually a flat rate to International locations. Those items where the rate is not listed must be treated on a case by case basis and customers should contact us for the rate to their specific location. All questions are always welcomed. |

Measurement Conversion Page
Northern Stones uses both inches and millimeters in its sizing of products. The following
chart compares millimeters to the nearest 1/32-inch, and commonly used inch measurements to
the nearest half-millimeter. This chart is a nearest approximation because the two units do
not exactly align.
For sizes not on the chart, simply add appropriate sizes together.
For example, 2 5/8" is equivalent to 1" + 1" + 5/8" = 25mm + 25mm + 16mm = 66mm

either inches or 1/16 inch graduations.
