These earrings are FABULOUS! I bought these as a gift for my wife, who works with algal communities, and she loves them. The attention to detail is immense, so if anyone is looking to buy a gift for that certain science fan for whom correct anatomic detail is important, this seller is the place to go.

My daughter is a professor of microbiology at a large university and, in the past, has worked with chlamydomonas as part of her research. I sent this pendant to her for her birthday, and she absolutely loved it! The designer made it a nice experience in every way.

My archaeopteryx necklace is simply the best thing I have bought for myself in a very long time. It is made well, has fantastic detail and would make any paleobiology buff happy! Highly recommend!

Shipment was fast and the earrings are elegant and delicately crafted! Radiolarians seem to have evolved to inspire human jewelry!

I love these earrings so much! They are the perfect size and go with just about any outfit. I get compliments all the time from both science and non-science friends when I wear them and I love that they don’t tarnish!! Can’t express how much I love these earrings!!!
