It does look like one of your strands is SSP. The fish bites and nacre is similar to what I've seen at Greenhills for SSP. I buy at Greenhills quite often. Only with 2-3 trusted vendors. I've also brought a few to a gemologist to verify if I plan to use a new vendor. IMHO depending on the harvest and what they get at auction, the SSP strand that you have would currently retail in that range ($700-$800) for that size and quality. For example, 10-11mm whites very good quality currently asking price is $3-4K and I bid down. Also I just did a big order within last two weeks. 9-10mm good quality FW asking price approx $80-100. So 8-9mm good quality (almost all round, no lines/striads/high luster) asking approx $60. All prices I negotiate down. I would say two at $185 they did ok but there was room to go lower.
