Not sure about your ring size? No problem! I offer a free sizer with purchase of a ring. Just select "Send me a free sizer" when you place your order, and I'll pop one in the mail for you. Once you know your size, send me a message, and I'll make your ring! (If you're not ready to buy a ring just yet, you can order the sizer by itself here.)
I make rings in US half and whole sizes. If you're ordering from outside the US, and don't know your US ring size, here's a handy ring size conversion chart for you.
If you're buying for someone whose ring size you don't know, BUT you have access to their other rings, (you sneaky Cassanova!) you can measure the Inside Diameter in Millimeters of an existing ring, and find the closest size in the chart above, under "Diameter (mm)," and corresponding US ring size. A good set of calipers will give you the most accurate measurement. This ring would be a US 6-1/2. *Please note the need for accuracy - the difference between a 6 and a 6-1/2 is only about half a millimeter!
