I would recommend JNBgems on etsy. I have purchased a lot of pearls from them over the years, both individual and strand-length, and the pictures are accurate and I think the prices are fair. I also love CMW. Their prices are fair and the pictures and videos are accurate for everything I have bought from them.
The strand on ebay from continental pearls is lovely, but I think the 3 pearls with large drill holes are problematic (and it is very nice that they did highlight those holes). They will likely either need to be remove when strung, or will take some finagling with gimp to make sure the hole is snug enough for the silk/thread so that they will not hang weird/obscure/fall down on the knots. I like that the strand is accurately represented, but in my opinion, there are a lot of fishbites and grooves without nacre, and again in my opinion, the price is high for that level of quality. Maybe they are super lustrous, which would drown out the imperfections, but I would be nervous about that...
Pearl Dreams, that is too true!!!
