The gold standard is Tortoiseshell, which is somewhat of a misnomer because the material used is from the Hawksbill sea turtle. Tshell is tightly regulated on an international level, so besides being fussy to maintain, it's illegal to buy/sell/trade uncertified shell. Getting shell certified is nearly impossible without letters of provenance exactly dating the shell or shell product to pre-1972, so as a consequence, Tshell picks remain a "gray-ish/black market" item.since u brought it up - what are picks made of??
Modern boutique picks are mostly made from aerospace- and industrial-use plastics and composites. Blue Chip picks are made from a proprietary polyimide composite called Vespel, and several pickmakers use a plastic called polyamide-imide (PAI, or Torlon - my favorite) for their products. A longtime favorite of pickmakers is polyetherimide (PEI), also called Ultem/Ultex. Another material with great qualities for picks is polyetheretherketone, or PEEK, and at least one boutique pickmaker uses a hardened polyoxymethylene (POM, or Delrin) as a pick material.
The cheap plastic picks that are 50 cents at guitar stores are made of a variety of low quality plastics. Great to learn with on an acoustic instrument, but that's about it IMO
