Ruby does not have any typical consistent clevage. Though it may show parting on twinned stones.
There is no cleavage. Simple as that.
The types of Opal that i am familiar with are White Opal, Fire Opal, Boulder Opal, Black Opal, Crystal Opal, Light Opal, Doublet Opal, Triplet Opal, Common Opal, Synthetic Opal, and Immitation Opal.
An Ethiopian opal is an opal-CT, whereas an Australian opal is an opal-A. The Ethiopian opal is made up of leptospheres, instead of small amorphous silica spheres like the Australian opal.

Boulder opal is distinct from black opal in the following ways: * Boulder opal is usually mined in open-cut operations while black opal is mined in shafts. * Boulder opal is found in ironstone boulders, while black opal is found in seams.
October's birthstone is the opal. The opal is thought to have the power to predict illness. This is because the opal responds to heat.

It is called fracture.

a diamonds cleavage is the cleavage of a diamond

Conchoidal Fracture. Clevage is impossible in a pearl
The fracture of an opal can be hard or smooth , An opal can have as many fractures as any other mineral can . Sometimes opal can be smooth , sometimes they can be hard . The fracture of an opal is hard and smooth .
