Besides bitcoins I also take paypal, personal checks, money orders, etc. Just get in touch with me via PM or at
dave@tiptopgem.com. I can find any stone that you would like- ruby, sapphire, emerald, diamond, tourmaline, pearls (Japanese Akoya and Chinese freshwater both), or any other gemstone under the sun.
Note that I am also an experienced custom jeweler! Any stone that you see on this thread can be made into jewelry with silver, gold (14K, 18K, 22K), platinum, or the latest hot exotic metal palladium. We can use a stone you already have as well. Send me a message and let's talk about your dream! We do CAD drawings so you can visualize how your jewelry will look before it's born. Take a look at the blog to see a gallery of our work:
