5 Ugly Creek Rocks Hiding Diamonds, Rubies & Sapphires

Rockhounding ugly creek rocks is how Sheila Taber found a 15.33 carat white diamond in Murfreesboro, Arkansas in 1964. I sort the 5 creek rocks most people kick downstream: kimberlite gravel, yellow ground, conglomerate nodules, schist, and dull agate nodules. Use the greasy wet thumb test, bucket water breakdown, knife scratch test, and an $8 pocket flashlight before you throw a rock back. This is creek bed mineral identification with mud on the hands, not display case fantasy. 💎 Sheila Taber’s 1964 Murfreesboro diamond weighed 15.33 carats and sold for $35,000 💎 Blue gray kimberlite should feel 20 to 30 percent heavier than the same size granite 💎 The wet thumb test checks for that greasy, soapy serpentine feel in real kimberlite 💎 Yellow ground breaks down in creek water and leaves ilmenite, magnetite, garnet, or clear chips 💎 Conglomerate nodules from the Sierra Nevada, Yukon drainages, and Queensland can trap gold flakes 💎 Schist with red or pink corundum spots should scratch a knife blade at Mohs 9 💎 An $8 pocket flashlight can separate glowing agate from dead basalt 0:00 Sheila Taber’s 15.33 carat Arkansas diamond 1:49 Kimberlite creek gravel and the greasy thumb test 4:07 Yellow ground and diamond indicator minerals 7:14 Schist, Yogo sapphires, and Mohs 9 corundum 9:25 Agate nodules and the $8 flashlight test Subscribe if you want rockhounding tests that put real stones in your hand. #rockhounding #gemhunting #mineralidentification #diamondhunting #agatehunting #creekrocks
