How big is the jewelry I see online?

The sizes listed on are in inches by width and height. Charm sizes do not include the top jump ring. If you have a question about the sizes of anything on the website please call 1-888-CBSTARK. Due to the variance of monitor resolutions, browsers, and photography techniques, items may vary in color and may appear larger or smaller than actual size.

How do I know what size ring or bracelet to order?


We offer most of our rings in a wide range of sizes. If you don’t see your size listed, please give us a call and we’ll let you know if we can make it. If you’re not sure of your size, we recommend you visit a reputable jeweler in your area to be sized, or call us and we’ll mail you a sizing gauge. If you’re buying for a gift and are unsure of the size, you can order the stock size and we can exchange it after the gift has been given (the ring must be in new and unworn condition to be exchanged). If a ring needs to be sized after it has been worn, we can size it for a fee.

Charm Bracelets

Our charm bracelets come in a variety of different sizes. The Signature Charm Bracelets can be made in any length. Please keep in mind that the toggle bracelets need to be slightly longer than normal to function properly.

Bead Bracelets

Please measure your wrist with a soft tape measure and add approximately one inch.

Island Tie sizing

Please measure your wrist with a soft tape measure where you would like the bracelet to lay, and order the closest size without going over. For instance, if you wrist measures 6 1/8” order the 6” not the 6 ½”. They do have some adjustment to them but they shouldn’t be too large.

Link style bracelets

(Multi Shell, Contemporary Island Bracelet) These bracelets come in one standard size, which is usually about 7” to 7.5”. We can always add another link or shorten one if needed. Please call us at 1-888-CBSTARK to discuss options.

Are your diamonds conflict-free?

We follow all industry standards to be sure that the diamonds we sell are conflict-free.

Are all CB Stark designs made on Martha's Vineyard?

We make many of our designs here on Martha's Vineyard, but due to space limitations our production is done at a casting facility in Massachusetts.

Are the images on my screen the actual size and color?

Due to the variance of monitor resolutions, browsers, and photography techniques, items may vary in color and may appear larger or smaller than actual size.

Do you gift-wrap?

All of our jewelry may be gift-wrapped at no extra charge. When ordering on-line please add a note in the special instructions and notes box of the checkout that you would like your item gift wrapped.

How long does it take to solder a charm on my charm bracelet?

It typically takes about seven business days to solder charms. Occasionally during our busy season, it can take longer, and in the off-season the wait might be less.

Will you solder a charm that I didn’t buy from you on my charm bracelet?

Yes, for a fee we will solder charms that were not purchased from us.

How much does it cost to solder a charm on my charm bracelet?

Charms purchased from CB Stark will be soldered at no charge. We will solder charms not purchased at CB Stark starting at $10 each in sterling silver and $15 each in 14k gold. Additional charges may apply if the charm needs a new jump ring in order to be soldered on the bracelet. If you are adding more than one charm, a discount may apply.
