Best way to setup jewelry shop in commerce

WHat is the best way to setup jewelry store?

We have many jewelry items,2000 to be exact.

We have similar design rings, with different stones, lets say one type or ring has stones liek Ruby, Amethyst, Zircon ...it can be 10 variations.

So if we create product variations for each stone it will take forever..

Lets say I have a ruby ring with sku 110R and I want to add variations with different stones, like for example

110am --amethyst stone
110zir - zirconia stone
etc
etc
etc
etc

I would have to add 10 different variations if we have 10 different stones right?

And do that for each content type right.

For example
I create second product

110am zirconia ring
and again I have to add 10 different variations

so to add 10 content type rings, I would need to add like 100 variations alltogether, for each content type 10 variations, right?

Is there an easier way to do this

Also we would have 4 differnt sizes for each ring, so that would be like 100 x 4, 400 different variations to add manually for 10 content types

I really need help on this one, any idea how to do this quicker than adding 400 variations?
