Start with the coin. A spinning bitcoin has a center that turns in its frame as you move, and a diamond bitcoin is set with natural stones. Then pick the metal. Silver is what sold here over the past year, the diamond coin above all, and the gold ones are 14K in yellow, white or rose. If you have no chain yet, two silver bitcoins come already strung on a Franco.
Spin or diamonds: the spinning bitcoin pendant and the diamond bitcoin pendant
Each piece here carries the bitcoin mark, a capital B with two short bars through its top and bottom.
On a spinning bitcoin the coin sits in a frame and rotates when you walk, so the B keeps flashing. Three are built like that. Silver makes two of them, and 14K gold the third.
The diamond bitcoins are prong set with natural round diamonds, G in color. Each silver diamond coin holds 0.62 carats, and the gold one 0.80. The last of the seven, custom made in solid 14K, lists no stones.
Silver or gold: .925 silver bitcoin necklace or 14K gold bitcoin pendant
Pick by color and care. Silver is bright and white, and sweat dulls it until a polishing cloth clears it. 14K gold keeps its color.
The gold bitcoins are all 14K, and each is made in yellow, white or rose. For a coin you never take off, 14K stands up to knocks better than 18K. Match the gold color to the chain you already wear.
Size and grams: how big a bitcoin pendant is and what it weighs
These run 1.25 to 1.75 inches across, roughly 32 to 44 mm. The diamond coins are the compact ones. The spinners and the custom coin are the wide ones, and the spinners hang longest at 2.25 inches.
Read the grams before the photo. The silver diamond coin by itself is 21.7 grams, light enough for every day. The silver spinner comes to 52, and the custom gold coin to 61.4, which you will feel on your chest.
On a chain: bitcoin chain sets and the chain for a bitcoin pendant
Two silver bitcoins, the diamond coin and the spinner, come strung on a Franco chain in 18, 20, 22 or 24 inches. The spinner's Franco is 3.2 mm wide and the diamond coin's is 2 mm. The other five arrive as the pendant only.
Buying one by itself, look at the bail, the loop the chain runs through. Your chain must pass it, and the clasp too unless the bail opens. Past 40 grams, hang it on a heavier link that lies flat, like a Franco or a rope. The gold chains guide shows where each length falls.
Made for you: a custom bitcoin pendant, and returns
A bitcoin can be drawn your way, bigger, in another gold color, or with stones on the rim. The jewelers at the store on 47th Street work from a sketch or a photo. Settle size and lead time before you order.
Made for you means final sale. Bought as shown, a bitcoin can be returned for fourteen days after it arrives, never worn or changed, still in its box. Clear it with customer service first, at service@traxnyc.com or 212-391-3832, since only the store's return label carries it back. From the refund we hold five percent for restocking, plus the bitcoin's return shipping. Questions go to the live chat before anything, or call or text 212-872-9692 from 10 AM ET.
