IS THERE A UNIVERSAL STANDARD for Promise ring looks?
There is no one shape or style that defines His And Hers Promise Rings. They're as diverse as their owners and the contemporary jewelry industry and artisans can provide an unlimited amount of creativity and style in their precious holdings.
However, since engagement rings are meant to be worn with other rings, particularly an engagement ring, here are some suggestions on the most suitable design and size of these rings.

In general the ring should be slim and discreet and can be worn in a variety of ways, and should not be too gaudy so as to overshadow an engagement or wedding band. The rest is up to you. If you're asking yourself: What finger has a promise ring? There are also basic answers.
RINGS with SMALLER DIAMONDS
If the engagement ring is large such as a large diamond solitaire or any other large stone surrounded with smaller stones (think about the famous sapphire engagement ring of the Duchess of Cambridge), then an engagement ring to match it could have a smaller diamond. A band with a starry diamond drop looks elegant by itself, and is a great match with other rings.
SIMPLE BANDS
They are the most adaptable styles, and they are typically unisex and totally identical in a set, thus visually indicating your relationship to someone else. You can pick a gold or silver band ring or a bimetal ring that has yellow gold exterior edges and white gold middle pieces. The only drawback is that these ring can be mistaken for wedding rings, so your promise ring finger must be distinct from the ring finger to avoid confusion.
Rings with BRITHSTONES
This is a fashionable and sensible way to choose a promise ring. If you are aware of your loved one's birthstone, zodiac stone, or lucky stone and they are in the spiritual realm, then you can purchase rings that contain this stone. These are the normal gems like pearls moonstones, opals, topaz, citrine, amethyst, etc. It is possible to easily find a pretty jewelry piece that has a tiny piece of this stone. The ring may have two meanings for the owner. She can inform people about what the promise ring on the hand represents without divulging personal details.
CLUSTER RINGS
A cluster of sparkling stones could look exactly as stunning as an enormous diamond. The delicate stone is more subtle and is a better match for bolder rings. You can select a cluster that looks like a single stone until you get close to it, or even a combination of lighter and darker stones that resemble a mosaic.
Small SIGNNET RINGS

RINGS WITH HEART-SHAPED ELEMENTS
