The Iridium disc from Element Discs was PDGA Approved as of 12-9-2015.

"The first release from Element Discs, the Iridium, is a beadless putt & approach disc featuring one of the thinnest flight plates out there. The flight plate has a subtle thumb track for consistent grip/alignment every time. This versatile disc is great for putts and upshots, as well as driving off the tee. The Iridium excels as a spike hyzer bomber that stops dead in its tracks when it hits the ground. The flight numbers: 2, 3, 0, 2" - by Element Discs
