Choose the metal first. The gold bitcoins are 14K, each in yellow, white or rose, and the silver ones are .925. Every one sold in the past year was silver, most of it the small coin with natural diamonds. Then choose the build: a plain coin, a diamond coin, or a spinning coin that turns as you move. The silver sets arrive on a Franco chain.
The coin: bitcoin pendant designs, plain, diamond or spinning
The bitcoin sign is a capital B crossed by two short strokes at its top and bottom. All seven pieces here are built around that mark, in three ways.
A spinning bitcoin has a coin that turns inside a fixed frame, so it catches light as you walk. Three spin, two in silver and one in 14K gold.
The diamond coins carry natural round diamonds, G in color. Both silver diamond pieces hold 0.62 carats, and the 14K coin holds 0.80. The seventh piece is a custom-made coin in solid 14K gold.
Gold or silver: 14K gold bitcoin pendant or .925 silver bitcoin necklace
Wear the coin every day and 14K is the one to take, harder than 18K. Each of the three gold bitcoins comes in your pick of yellow, white or rose.
The spinning coin is the same size in silver and in 14K gold. Silver darkens with air and sweat, and a jeweler's cloth brings it back in a minute.
Size and weight: how big a bitcoin pendant is and how heavy
They run 1.25 to 1.75 inches wide, about 32 to 44 mm. The silver diamond coin is the small one, and the spinning coins and the custom piece are the big ones.
Size does not tell you the weight. The silver diamond coin weighs 21.7 grams alone. The 14K spinning coin comes to 44.6, and the custom gold coin to 61.4. Set those grams beside a pendant you already wear.
The chain: bitcoin necklace sets and the right chain for a pendant
Two silver bitcoins come as a set on a Franco chain, the diamond coin and the spinning coin, with the length yours to choose from 18 to 24 inches. The spinning set has the thicker chain, 3.2 mm, and the heavier coin. Every other piece is the pendant by itself.
For a pendant by itself, look at the bail, the loop at the top. Your chain, and its clasp unless the bail opens, has to fit through it. A coin past 40 grams wants a strong link that hangs flat, a Franco, a rope or a Cuban. The length finder in the gold chains guide shows where each length lands.
Custom: a custom bitcoin pendant made for you
For your own bitcoin, with your initials beside the B or diamonds around the rim, send a sketch or a photo. The jewelers make it at the store on 47th Street, in the gold you choose.
A piece made for you is final sale. One bought as it comes may be returned inside fourteen days from delivery, unworn and unaltered, in its packaging. Clear it with the desk first so it travels on the store's return label. For restocking we hold back five percent, and the return label comes out of the refund.
