An engagement ring does not need to follow a traditional formula to feel timeless. For couples who prefer distinctive gemstones, unexpected colors, and designs with an artistic personality, Midwinter Co. offers an appealing alternative to conventional jewelry stores.

The independent jewelry studio specializes in one-of-a-kind engagement rings, salt and pepper diamonds, unusual sapphires, custom settings, and modern wedding bands. Its designs often celebrate the natural inclusions, shifting colors, and irregular characteristics that make each gemstone unique.

In this Midwinter Co. review, we take a closer look at the company, its gemstones, custom design experience, popular jewelry styles, pricing, production times, shipping, returns, and warranty.

What Is Midwinter Co.?

Midwinter Co. is a small independent jewelry company founded by a husband-and-wife team in 2013. Its flagship studio is located in Wilmington, Delaware, and is open by appointment.

The company describes itself as a relationship-focused business rather than a traditional jewelry retailer. Customers often work directly with members of the team, who help them understand the available stones and create a piece that represents their personal story.

Midwinter Co. emphasizes a comfortable, low-pressure shopping experience. There are no conventional commissioned salespeople. The people assisting clients are also involved in operating the studio and managing the jewelry-making process.

This personal approach is particularly attractive for customers who find traditional engagement-ring shopping formal, intimidating, or too focused on standardized diamond grades.

What Makes Midwinter Co. Different?

Midwinter Co. is best known for gemstones that do not look perfectly uniform.

Traditional jewelers often prioritize diamonds with as few visible inclusions as possible. Midwinter Co. takes a different view, selecting stones whose internal patterns, colors, and natural characteristics create individuality.

The company works with an unusually broad range of stones, including:

• Salt and pepper diamonds

• Celestial and galaxy diamonds

• Black diamonds

• Gray and opalescent diamonds

• Teal and bi-color sapphires

• Parti sapphires

• Moss agate

• Dendritic agate and opal

• Mossy aquamarine

• Tourmaline

• Spinel

• Garnet

• Alexandrite

• Morganite

• Emerald

• Peridot

• Topaz

• Quartz with distinctive natural inclusions

Many of these stones feature visible patterns that resemble clouds, branches, stars, smoke, moss, or distant landscapes. The inclusions are treated as part of the design rather than imperfections that need to be hidden.

Salt and Pepper Diamond Rings

Salt and pepper diamonds are central to the Midwinter Co. identity.

These are natural diamonds containing visible light and dark inclusions. Depending on their appearance, they may look smoky, misty, speckled, icy, celestial, or nearly black.

No two stones have exactly the same internal pattern. This makes them especially appealing to customers who want a ring that feels truly personal.

Midwinter Co. offers salt and pepper diamonds in familiar shapes such as round, oval, pear, cushion, emerald, and princess cuts. The collection also includes less conventional shapes such as hexagons, kites, shields, crescents, trillions, and geometric cuts.

The variety allows customers to choose between romantic, vintage-inspired, minimalist, dramatic, and distinctly alternative styles.

Unique Sapphires and Colored Gemstones

Midwinter Co. is not limited to diamonds. Its sapphire and colored-gemstone selection is equally important.

Teal, blue-green, gray, icy blue, parti-colored, and geometric sapphires appear throughout the collection. These stones bring more color to an engagement ring while retaining the durability that makes sapphire a practical choice for regular wear.

Other gemstones provide even more expressive possibilities. Moss agate can contain patterns resembling small natural landscapes, while dendritic stones may display branch-like inclusions. Tourmaline, spinel, garnet, and aquamarine offer a wide range of colors and moods.

Because many stones are one of a kind, a sold design may not be reproduced exactly. Midwinter Co. can often create a similar ring using the same setting and a comparable stone, but the natural pattern will remain individual.

Ready to Size and Ship Rings

Customers who prefer to see a completed design before making a decision can explore the Ready to Size and Ship collection.

These rings already combine a center stone with a finished setting. If the existing size and metal finish are suitable, the piece can generally be shipped within one to three business days.

If resizing is required, preparation usually takes one to two weeks. Recasting a ring in a different metal color can extend the timeline to approximately four to six weeks.

This collection offers a convenient balance between purchasing a finished ring and receiving some personalization. Buyers can examine the complete relationship between the gemstone, setting, metal, and accent stones before committing.

It is important to remember that resizing or changing the metal finish turns the ring into a customized piece and may affect return eligibility.

The Custom Ring Experience

Customization is one of Midwinter Co.’s greatest strengths.

Customers can begin by choosing an in-stock stone and pairing it with one of the company’s settings. The Midwinter Co. team adjusts the setting to fit the dimensions and character of the selected gemstone.

Another option is to submit a fully custom inquiry. Customers can provide a target budget, reference photographs, sketches, preferred colors, gemstone ideas, and examples of design elements they enjoy.

The team can then help with:

• Selecting or sourcing a center stone

• Choosing a metal color

• Combining elements from existing settings

• Developing a completely new setting

• Creating matching wedding bands

• Designing a custom contour band

• Producing couples’ rings or stacking sets

• Creating a new piece inspired by a previously sold design

Clients remain involved throughout the process and approve important design decisions before the ring enters production.

Midwinter Co. works only with gemstones sourced by its team and settings it has designed. It generally does not set stones supplied by customers or sell empty settings separately.

Loose Gemstones

Customers may purchase selected in-stock stones without immediately adding a setting. There is generally a limit of two loose stones per client.

This can be useful for someone who wants to propose with the gemstone and design the final ring together afterward. Eligible U.S. customers can choose an option that adds a setting deposit, allowing the stone to return to Midwinter Co. for completion later.

Loose-stone purchases are final and do not include a warranty. Certain open-market stones must be purchased with a Midwinter Co. setting and cannot be shipped loose.

Buyers who want formal grading for an eligible gemstone can ask about obtaining a GIA report before the stone is set.

Materials and Sustainability

Midwinter Co. positions sustainability as an important part of its identity.

The company states that more than 90 percent of its metals are recycled. It also emphasizes ethically sourced materials and environmentally conscious studio practices.

Using recycled gold and other metals can reduce demand for newly mined material while maintaining the beauty and performance expected from fine jewelry.

The company works primarily with durable precious metals such as 14K gold in yellow, white, rose, and less common green tones. The broad metal selection makes it possible to create combinations that feel warm, understated, romantic, or contemporary.

Popular Designs and Pricing

Midwinter Co. operates in the premium independent-jewelry category. Prices reflect the size and rarity of the center stone, complexity of the setting, metal choice, and amount of accent detail.

Examples from the collection include:

• Orion Setting: approximately $1,900

• Nova Band: approximately $1,500

• Rough Diamond Solitaire Ring - Made to Order: approximately $850

• Dendritic Opal Pear Ring - Made to Order: approximately $850

• Orion Ring with a Round Moss Agate and White Accent Diamonds - Made to Order: approximately $2,400

Premium and custom designs can exceed $10,000, particularly when they include a large center stone or extensive accent diamonds.

The loose-stone inventory offers additional flexibility. Prices may begin around $1,250 for selected stones and rise above $7,000 for larger or rarer diamonds.

Prices and availability change regularly because many gemstones and completed rings are unique.

Production Times

Production time depends on the type of jewelry being ordered.

Typical estimates include:

• Ready to ship without changes: one to three business days

• Ready ring requiring resizing: one to two weeks

• Ring recast in another metal tone: four to six weeks

• Custom stone and setting combination: four to eight weeks or longer

• Fully custom metal work: approximately four to six weeks after design approval

• Complete bespoke process: sometimes 10 to 12 weeks or longer

• Wedding bands: approximately four to six weeks

• Custom contour bands: approximately four to eight weeks

• Made-to-order jewelry: approximately three to six weeks

Custom gemstone sourcing may require a few weeks or several months, depending on how unusual the request is.

Rush production and expedited delivery may be available on a case-by-case basis. Customers with a proposal or wedding date should contact the studio before ordering to confirm whether the timeline is realistic.

Shipping

Midwinter Co. provides complimentary insured shipping with tracking.

Domestic U.S. orders are generally sent through FedEx Two Day service. USPS may be used for orders delivered to a post office box. An adult signature is required for most valuable shipments.

International orders are sent through DHL Worldwide Express, with an estimated transit time of two to seven days after production is complete. Shipping is insured and requires a signature.

Packages use discreet exterior packaging without the Midwinter Co. name or logo, which is useful for customers planning a surprise proposal.

International customers are responsible for import duties, brokerage fees, taxes, and other charges required by their country. These fees are separate from the complimentary shipping service.

More details are available on the company’s shipping information page.

Returns, Exchanges, and Cancellations

Policies vary depending on whether an item is ready to ship, resized, customized, made to order, or purchased as a loose stone.

Most orders can be canceled within 24 hours for a full refund. Certain orders canceled later may be subject to a $250 fee, and cancellations are not available after 21 days. Some product categories have stricter conditions.

Unmodified Ready to Size and Ship pieces may qualify for a return. Return fees are generally $120, while qualifying exchanges have a $50 fee. Customers are responsible for insured return shipping with an adult signature requirement.

Once a ready ring has been resized or its metal finish has been changed, it is treated as customized and loses its standard return eligibility.

Fully custom work is not returnable. In some circumstances, a custom piece may be exchanged within seven days for another item priced at least $1,000 higher.

Loose gemstones are final sale.

Because each piece can have different terms, customers should review the specific policy attached to the product before paying. The complete details are available on the returns and cancellations page.

Warranty and Care Plans

Midwinter Co. includes a complimentary limited warranty with jewelry purchases delivered within the United States.

For pieces valued above $1,000, coverage generally includes:

• Prong repair or tightening for five years

• Repair of a bent shank for five years

• Replacement of accent stones smaller than 2 mm for five years

• The first resize at no charge

For pieces below $1,000, comparable repair coverage generally lasts 90 days, and the first resize remains complimentary.

The center stone is not covered against damage or loss. Theft, complete loss, major setting reconstruction, normal wear, and certain types of damage are also excluded. Customers pay insured shipping to and from the studio for warranty service.

International orders placed from April 1, 2024 onward do not include the complimentary warranty.

Customers wanting broader repair protection can purchase an optional Jewelers Mutual care plan. Separate jewelry insurance is recommended for theft, disappearance, or center-stone loss.

Full coverage details can be found on the Midwinter Co. warranty page.

Who Should Consider Midwinter Co.?

Midwinter Co. may be especially suitable for:

• Couples looking for a nontraditional engagement ring

• Customers who appreciate salt and pepper diamonds

• People drawn to teal, gray, black, and bi-color gemstones

• Buyers who value natural inclusions and unusual stone shapes

• Customers who want a one-on-one design experience

• Couples interested in custom or matching wedding bands

• Shoppers who prioritize recycled metals

• People who prefer an independent studio over a large jewelry chain

• Customers comfortable planning several weeks ahead

The brand is particularly compelling for someone who views natural variation as part of a gemstone’s beauty.

Is Midwinter Co. Worth It?

Midwinter Co. is worth considering if individuality matters more to you than conventional perfection.

The company’s strongest advantage is its ability to pair unusual stones with refined, wearable settings. Salt and pepper diamonds, geometric sapphires, moss agate, dendritic gemstones, and unexpected color combinations give the collection a recognizable personality.

Its custom process also offers meaningful flexibility. Customers can begin with an existing stone, modify elements from previous designs, or collaborate with the team on an entirely new piece.

Prices are higher than those of mass-market jewelry brands, but each ring reflects small-studio production, specialized stone sourcing, precious metals, and detailed design work. Complimentary insured shipping and the included U.S. warranty add further value.

The main consideration is that personalization limits return options. Customers should take advantage of consultations, request visual references when needed, verify sizing, and understand the relevant policy before approving a custom project.

Final Verdict

Midwinter Co. offers an imaginative and personal alternative to conventional engagement-ring shopping.

The studio’s greatest strength lies in recognizing beauty where traditional jewelry standards might see imperfection. Natural inclusions, smoky colors, asymmetric patterns, and unconventional shapes become the defining features of each design.

Its combination of one-of-a-kind gemstones, recycled metals, custom settings, personal consultations, and a low-pressure studio experience makes the brand especially appealing to modern couples seeking something meaningful and uncommon.

For anyone searching for an engagement ring that feels artistic, individual, and connected to the natural character of its gemstone, Midwinter Co. is a memorable jewelry studio worth exploring.
