Avalanche K10 necklace and pendant set. Necklace length: 45cm Total weight: 3g or more I'm selling this to buy new gold. I bought this at the Odaiba Avalanche store. There are no certificates or boxes. The pendant features a horseshoe design, said to bring good luck, with the AVALANCHE logo and a 3D star, and is set with one diamond. Now is a good time to buy as the price of gold is rising. K10 gold has a lower gold purity than K18, but K10 has the advantage of being "durable" due to its lower purity, allowing for more elaborate designs, making K10 a good choice. I regularly maintained the necklace. I soaked it in a gold cleaning solution and then polished it with a cloth. It shines beautifully. Feel free to comment.
