Although I have purchased some great household and decorative items, I would caution bidders to be extremely careful when buying diamond jewelry. I bought a diamond necklace that arrived with tan diamonds. When I went back and read the pull down item description, it listed tan diamonds. I felt that this information should have been in the banner not hidden in Item Description. I felt duped.
Also, unlike eBay, it it difficult to ascertain the size of jewelry pieces. Almost all sizes are in mm, so unless you are a gemologist, it is hard to determine sizes. I purchased what appeared to be a nice sized pendant with several diamonds, and I tried to determine the size based on mm. It was so tiny, approximately a 1/4 inch that I thought I had been sent the wrong item. eBay will show pieces against a ruler so at least bidders have a visual for size comparison.
So, considering the risk of getting stuck with expensive, unused items, I now pull out of bidding on expensive jewelry.
To my knowledge, there are no returns on this app as compared with eBay.
