Petrified palmwood is more properly referred to as a fossil rather than a stone.

Regardless, Petrified palmwood became the official state stone when Governor Preston Earnest Smith signed House Concurrent Resolution No. 12 on March 26, 1969.

House Concurrent Resolution No. 12 also named the Texas blue topaz the official state gem of the State of Texas.

In Texas, petrified palmwood is principally found in eastern counties near the Texas Gulf Coast.

Though House Concurrent Resolution No. 12 identifies the state stone as petrified "palmwood," the stone is often referred to as petrified "palm wood."

H.C.R. No. 12

House Concurrent Resolution

WHEREAS, The State of Texas has not officially designated a state gem or a state stone; and

WHEREAS, The Texas Gem and Mineral Society has adopted appropriate resolutions in support of designating the TEXAS BLUE TOPAZ as the official State gem and PETRIFIED PALMWOOD as the official State stone; and

WHEREAS, It is appropriate that the State Legislature take the necessary action whereby the TEXAS BLUE TOPAZ and PETRIFIED PALMWOOD may be officially named as the State gem and the State stone, respectively; now, therefore, be it

RESOLVED, By the House of Representatives of the State of Texas, the Senate concurring, that the recommendations of the Texas Gem and Mineral Society be and are hereby adopted, and that the TEXAS BLUE TOPAZ be and is hereby declared to be the official State gem and PETRIFIED PALMWOOD be and is hereby declared to be the official State stone of Texas.

It[petrified palm wood] comes from palm trees in the Oligocene Epoch, between 20 - 40 million years ago, give or take a few years.

The characteristic spotted look of palmwood is from the rod like structures within the grain of the wood. Depending upon the angle the lapidary uses to cut the stone, these structures show up as spots, tapering rods, or lines.

Petrified palm wood is a variety of chalcedony and is very hard, around 7 1/2 on the Mohs scale of hardness and takes a wonderful polish which makes it a great stone for jewelry.
