The other day I blogged about engagement rings and encouraged people to try what works. Emeralds work. They are hard and very eye catching. The only problem is many of the natural stones are a bit cloudy. This is why I would go with a 3 layer eternity ban with diamonds VS1 or better and 10 point clean natural emeralds. In my opinion Trellis Eternity Bands look the best. However, this piece from Suzy LeVian can give you a nice visual.
Use it as a wedding set by making all the stones 10 points. Platinum wouldn’t be a bad upgrade either. Someone could definitely get this ring made for less than $10K.
If you don’t like Emerald go with Sapphires. Maybe you want all diamonds. Lauren B has some of the cutest stackable rings. You could skip the center stone and get 3 of them.
Just more to think about.
