I can advice you on this because I had the same question before. I purchase from them and a company recommsend here and ask why one was much cheaper. They said buy both and you can know why it is cheaper. The quality was different. But I also then had a problem sending the pearls back to Laguna pearl. I have to call to get authorise to send it back but only leave a message and nobody call me back. Finally I dial the extension for sales and speak to a Mr. Leon that said I have to speak to the return person. Finally I speak to Sam and he said that my husband have to call for the number because I ordered with his credit card. It was crazy! I am his wife and we share the name. Finally I can return the pearls but I wasn't happy with the experience.
