Thank you for looking at this necklace that I created. Its a very cool fashion statement very long 37" inches long . I used a high quality aluminum lightweight "heavy" cable chain with an antique brass look. It's only 53 grams but looks like 300 grams. This way you can wear it comfortably without hurting yourself. The heart lock is 1.5 inches long x 1.25 wide Romantic, antique, punk rock, steam punk, steampunk, boho, gothic, locket, key, padlock DOUBLE CHAIN Is for display only , no clasp
