I love gold rings with a resin core! I have one, which has outlasted my other gold rings by years!
When gold prices are high, there just isn't enough thickness to gold rings in the lower price range, to make them durable. My favorite large band rings are in the scrap-gold pile while the braided, resin-core ring that I never remove, is still wearable, with no dings and is not misshapen. It is scratched and worn, but intact.
