As a very special treat to myself after selling a piece of property, I bought a very expensive pair of earrings-$1399- that were advertised as being 32 carats of opal and diamond. When they arrived, there was no packing slip and no certificate of authenticity. I called and asked them to provide some verification that these are actually the gemstones as advertised which they told me they cannot do. I brought them to a jeweler who said he thinks the diamonds (tiny, tiny) but does not think the 32 carat stones are opal. They were luminous in the photo online, but dull in reality. Do not buy from this company! I have unsubscribed and intend to follow up with the authorities.
