If you feel you need a black diamond stackable ring, below are some of the stacking types found in the market.
If you are in love with the exact style of the band but want a little variety, you can add some difference to the metal choice. A tri-color stack with a yellow gold solitaire engagement ring and a twin band in white gold is a great choice.
Adding to the Stack
For a bride who isn’t bond by matching designs, the first wedding band on the bottom can be a shank style for the engagement ring. This has smaller diamonds and a thinner band, but an identical setting style. The center band can be something with a splash of rose gold.
