Best Places to Buy Promise Rings

Promise rings carry a lot of intention and mark a memorable moment in a relationship—not necessarily a proposal, but a meaningful step forward to show love and commitment.

Before moving forward, it helps to understand how these rings differ from engagement rings.

Promise vs. Engagement Ring: Key Differences At A Glance

Quality craftsmanship, transparent details, and fair policies all play a role in making sure the ring feels as lasting as the promise behind it. For that reason, where you buy it matters.

Rare Carat is one of the best places to buy promise rings, offering certified stones, expert support, and careful inspection before a piece ever ships.

Here’s what makes the difference.

1. Rare Carat’s Collection of Ring Styles

From simple, minimal bands to gorgeous solitaire stunners, although there are many different styles, finding the right one for you is not that hard. The perfect ring that symbolizes a promise should ideally match all your preferences, requirements, and budget considerations.

Once you find a design that speaks to you, choosing such a ring becomes easier. For this reason, Rare Carat is here with the largest collection of any jeweler in the USA, with 1,700+ ring styles. And the best part: it’s a wide collection yet not overwhelming. Our advanced search filters help simplify the experience. With them, you can narrow designs by shape, setting style, metal type, and even diamond shape, size, and type.

Some popular styles that can help express your promise include the following:

2. Certified Natural and Lab Diamond Options

Plain bands (with no diamond detailing) are quite popular as promise bands because of their everyday durability, wearability, and comfort. However, diamond rings are equally popular, especially with the industry shift driven by the availability and affordability of lab-created diamonds.

Mined stones are beautiful, rare, and considered the traditional choice. At the same time, many conscious buyers recognize that ethical lab diamonds offer the same physical, chemical, and optical properties as mined stones.

For this reason, shoppers must receive the choice between the two to ensure they are buying as per their preferences. At Rare Carat, the choice is provided from the get-go for a seamless shopping experience. No matter what you choose, rest assured that all diamonds available will be certified by one of the industry’s top grading labs: GIA, IGI, or GCAL.

That’s not all; once we source the diamonds, each stone undergoes an additional two-step verification process at our facility. We conduct these authentication and inscription checks to ensure every detail of the stone matches its certification.

If something is not up to our inspection standards, it is sent back to the lab for correction. Only then is the diamond made available for our customers. For instance, if the microscopic laser inscription on the diamond’s girdle isn’t clear or legible, we take the necessary steps to ensure shoppers are getting only quality diamonds.

3. Expert Gemologist Guidance at No Cost

From advanced diamond filters based on the 4Cs and price to superior, high-resolution diamond imagery with professional 360° videos for maximum transparency, the diamond buying process will be confident with us. And to further ensure this, we have our team of over 100 GIA-certified gemologists available for our customers for free chat as and when required.

Their opinions are unfiltered and grounded in real expertise and always focused on helping you choose a diamond that will look truly beautiful in person for a well-informed promise ring shopping experience.

4. Excellent Craftsmanship with Strict Quality Standards

Instead of mass production, Rare Carat believes in crafting each ring with care, one at a time, by expert jewelers in our New York and New Jersey workshops. Because of this unwavering commitment to quality, you are truly receiving a ring made specifically to celebrate your promise.

Once the ring is designed, it undergoes a microscopic quality inspection conducted by a team of independent QA specialists. This is done to ensure each piece meets all our standards. Even the smallest discrepancy is not overlooked—no shortcuts are taken. The ring is remelted and built from scratch.

While diamond detailing is usually traditional for proposal rings, a promise ring offers the flexibility of personalizing the ring with other gemstones.

Take this bestseller, for example. You can switch out the gemstones with options like ruby, diamond, sapphire, and more, along with the setting metal, to craft a ring that represents not only the promise and your special relationship but also the wearer’s style or preferences.

6. Selecting The Setting Metal & Size Option

When buying diamond jewelry for a memorable moment, focusing too much on what style represents what is not helpful. You should instead consider making the piece align with all your requirements, including the wearer’s style preferences and lifestyle. With easy customization options, even an unwanted style can be personalized to make it perfect just for you.

At Rare Carat, not only can you customize the diamond’s shape, color, cut, clarity, and carat, but also the setting’s style and metal choices. All popular options (platinum, yellow gold, rose gold, and white gold) are included for all our designs to ensure you can find what you are looking for.

We offer size customization as well. You can also resize your ring once at no charge within your first year.

Please note: For Eternity Rings, the free resizing period is for the first 30 days.

7. Secured Shopping and Customer Protection

We provide branded, premium packaging, complete with protective materials and a sleek finish for each ring. However, it will arrive at your address in a nondescript box via FedEx or UPS. We knew that only offering free insured shipping was not enough, and for this reason, we take such extra steps.

We also offer an in-house customer service team that is very responsive and helpful in processing returns and exchanges as needed. Along with a free 30-Day returns, we also have a 100% money-back guarantee for our customers.

Such dedication and transparency have helped us to rank as the number one business in the Trustpilot "Jeweler" category by reviewers for the second consecutive year, with more than 3,000 verified reviews.
