Here's an article with larger close-ups of Meghan's redesigned engagement ring band (and a before pic). She's also shown wearing the eternity ring with the wedding band. Apparently, Harry had the engagement band redesigned because the Welsh gold wedding band was enough of a heavy gold band that the similar heavy gold band on the engagement ring was a bit too much in terms of aesthetics as well as heaviness on Meghan's finger. Or else, it was just preference since Meghan appears to like delicate, minimalist jewelry:
I think the diamond band for the wedding ring matches the ring better than the gold band. However, the diamond band seems a bit too thin for the size of the three stones that make up the ring. The eternity ring and the Welsh gold wedding band look great together.
Another great piece of jewelry is the Cartier love bracelet with chastity lock that Harry gave to Meghan. Here's more information on the bracelet's genesis and design, plus a close-up view:
Wiki provides fascinating background on when the bracelet was made; how it's a popular seller; the fact that security at airports say it's the most problematic item because it needs to be removed to go through security gates, and a tool is needed to unlock the bracelets, which owners may not have with them. In fact, as Wiki indicates, the unlocking screwdriver is often placed on a necklace and worn around the neck of the owner's lover or significant other.
It's perhaps best not to wear such a bracelet when you are traveling via commercial air flights!
