We start with the micro pave round diamonds - each is set into luxurious pink gold - which lends its color to them.

Their brightness is an asset here - combining with the pink reflections to turn them into teeny pink-white searchlights.

This goes for both the ones on the lever back and those surrounding the wonderful orange brown cushions.
The earrings dangle about 7/8 of an inch.

The cushions are the star of the show, which is saying a lot considering what they are up against.

How they manage to have such a deep color yet be so bright, is a wonder to me.

The cut has a lot to do with that. Clearly cut by the same hand, they are as close to a perfect match as I have seen.

Each stone has a smallish table - I would estimate each at about 62%.

This combines with a tall crown to give somewhat of an antique sensibility to the proportions - but the modern faceting changes that.

Without that, you would never get the concentration of color of these guys.
