I am considering ordering a diamond accented wedding set made by Lieberfarb. The Shane Co sells this for significantly less than anywhere else around me. The wedding band would need to be ordered and take 8-10 weeks to come in there, whereas other jewelry stores can get it in 7-10 days. When I inquired why the wait is so much longer at Shane Co, they told me that they send their own diamonds to the manufacturer (all SI, G or H in color) and make sure they all match. I am wondering if I order from another jeweler who does not send there own diamonds, will I be getting inferior diamonds from Liebarfarb? I am not any expert on diamonds. Are the diamonds at Shane that much better? The t.c.w. on engagement is .14ct and wedding band .18ct. I would like to know that I am getting as pretty, sparkly diamonds as possible. Thanks!
