Lono (Black Cat) fashioning Blue Apatite. Lono tends to over use his voice and Blue Apatite helps with scaling it back.
Pele (Pink gray squared collar) showing her bling with Citrine. Pele tends to be less assertive, and Citrine helps her to seek alternate plans when Lono tends to exert dominance.
As with all pet care products, check for wear and replace to prevent injury.
