Calcite Crystals in Clam Shell Fossils Ruck's Pit, Florida USA
#1
3 x 1 3/4 x 1 1/8" Cluster of calcite crystals on calcified fossil shell on matrix. The longest crystal is 1/2"
#2
3 1/4 x 1 3/4 x 1 3/4" Lots of gummy dogtooth calcite inside both sides of about 1/4 fossil shell. the longest crystal is 1/2"
#3
3 1/8 x 1 3/8 x 2 1/8"
Large cluster of calcite crystals in both sides of a shell on matrix. Crystals are small but there are dozens, maybe a hundred in the cluster.
#4
3 x 1 5/8 x 1 1/2
Large cluster of 1/2" dogtooth calcite crystals on the bivalve portion of a fossil clam shell. Underneath, attached to the matrix, is another fossil shell, a bivalve NOT a clam shell.
#5
#5 side 2
3 1/4 x 2 3/4 x 1 1/2" Calcified half shell filled with calcite drusy and a cluster of larger crystals (up to 3/8") in the bivalve area. When viewing with a belomo loupe, the grey matrix inside the shell has tiny crystals all over it.
#6
#6 side 2
3 x 2 1/8 x 1 1/4" Calcified fossil whole clam filled with calcite drusy and clusters of up to 1/2" dogtooth calcite crystals.
#7
2 3/4 x 1 3/4 x 1 5/8"
Clusters of 3/8 to 1/2" dogtooth calcite on a fossil bivalve skeleton with just a small amount of matrix. Exquisite piece!
#8
2 3/8 x 2 x 1 1/8"
Whole calcified fossil clam shell with dogtooth crystal clusters in bivalve area. Some matrix inside the shell; will make a lovely display piece.

Two very large, two large, multiple smaller golden calcite crystals inside the bivalve portion of a fossil clam shell on matrix. The very tip of the largest crystal is chipped off but the piece is still exquisite. The largest two crystals measure 1 1/2 and 1 3/8 inches long.
#10
3 1/4 x 2 1/4 x 2"
Half of both sides of a fossil calcified clam shell filled with a bed of dogtooth calcite crystals. The largest is about 1/4"
Ruck's Pit, near Fort Drum, Okeechobee County, Florida USA held the most amazing fossil clam shells filled with beautiful, gummy, golden calcite crystals. The "Pit" is now closed, but a search on the internet will yield a phone number of the owner of the property and permission is still given to go through the piles left from quarry operations. Over 150 identified species have been found from snake vertebrae and horse teeth to cowry shells and mollusks.
The specimens on this page are Calcite in Mercenaria permagna from the Pilocene - Pleistocene eras and all fluoresce and phosphoresce dull yellow green in SW and LW.

3 x 2 1/4 x 1 3/8"
This piece is nearly all calcite crystals. The bivalve portion of the clam shell remains - it measures 1 1/2 x 3/4" and some matrix was left on the piece - there are some calcite crystals attached to the matrix. The largest of the large crystals measures 1 3/8" long and 3/4" wide! This is an extremely beautiful piece and will display nicely.
#12
3 1/4 x 2 3/4 x 1 5/8"
Top half (both sides) of a clam shell fossil filled with dogtooth calcite crystals. The largest crystal is about 5/8" long.
#13
2 5/8 x 1 7/8 x 3"
Both sides of a fossil clam shell portion filled to overflowing with beautiful calcite crystals. Plenty of matrix was left and forms a natural stand for displaying this wonderful piece. The longest of the crystals measures 1/2"
#14
2 1/2 x 1 7/8 x 1 5/8"
Bivalve portion of a fossil clam shell on matrix filled with Calcite crystals. The majority of this piece is calcite. Crystals range up to 3/8" long.
#15
2 1/8 x 1 5/8 x 1 3/4"
This is a really unique piece. The edge of the original shell extends the length of the matrix. The crystals grew where the meat of the clam was attached at the joint of the bivalve. The large cluster of bright crystals is very beautiful, the longest crystal measureing about 3/4"
#16
2 3/4 x 2 x 1 7/8"
Very nice specimen. Both sides of a clam shell - about a quarter of the original - filled with a little matrix and lots of large calcite crystals, the largest about 3/8" long.
