Love is in the little details and while it can be a bit chaotic, the whole is often greater than the sum of its parts.
I highly recommend the polished Silver.
But if your budget is a bit tight, the (Red) polished strong & flexible
(from $15.00) is also stunning.
You can attach the pendant to a necklace with a 7mm split ring or similar. (Not included)
Sizing
This smaller pendant is little over 0.9 Inch tall (2.22cm)
The medium pendant is little over 1 Inch tall (2.78cm)
This design was created using a custom voxel-engine:
Hearts grow, float and multiply within the outer shell, until they are tightly packed as one and they settle down.
Matching earrings are available too.
