hi all apologies if i have placed this message in the wrong section , i found this rock on the beach in east riding of yorkshire , had to have it the second i seen this with its colours going crazy lol.
would like to know if this is jasper and the name of it. been researching on line but getting few different names getting a bit confused with it. think it also has some moss pattern on it so has this turned into agate? the weight of it is 463 grams
thank you in advance
