Shopping for an engagement ring used to mean walking into a jewelry store, standing under fluorescent lights, and pretending to know what you were looking at. That has changed. Most couples now start their search online, comparing stones and settings from their couch, often at midnight, often with a dozen browser tabs open.
The problem is that there are too many options. Some retailers sell mass-produced rings at markup prices. Others offer customization but lack transparency about sourcing. A few get everything right.
Blue Nile: The Online Pioneer
Blue Nile launched in 1999 and helped establish online diamond buying as a legitimate alternative to brick-and-mortar stores. Their inventory runs deep, with over 500,000 loose diamonds searchable by cut, color, clarity, and carat. Prices tend to sit below traditional retail because they operate without physical showroom overhead.
Their customization tool lets you build a ring step by step, pairing any loose stone with your preferred setting. They include a GIA or AGS certificate with every diamond. Returns are accepted within 30 days with free shipping both ways.
Blue Nile works well for buyers who want access to a massive selection and prefer to compare technical specifications across hundreds of options. The trade-off is less personalized service compared to bespoke jewelers.
James Allen: 360-Degree Diamond Viewing
James Allen pioneered the 360-degree diamond viewing technology that lets you inspect a stone from every angle before buying. This feature alone has made them a favorite among detail-oriented shoppers who want to see exactly what they are getting.
Their inventory includes over 400,000 diamonds, both natural and lab-grown. The site lets you view each stone under magnification, which helps you spot inclusions that might affect appearance even if they do not affect the clarity grade.
They offer 24/7 customer support, free resizing within the first year, and a lifetime warranty covering manufacturing defects. Production typically takes 2 to 3 weeks for custom rings.
GOODSTONE: Bespoke Rings Handcrafted in Los Angeles
GOODSTONE was built on a simple idea. Keep the process personal, keep it honest, and let the buyer be part of the creation. That approach has since drawn 165K Instagram followers and earned features in Elle USA and Rolling Stone, and the company has held onto those founding values as it has grown.
Every ring is made to order by generational artisans in their Los Angeles workshop, where you can choose a setting and select a diamond, natural or lab-grown, with guidance on the 4 Cs from their team. Turnaround runs 3 to 4 weeks, and their single-price model covers resizing, insured shipping, cleaning, inspections, repairs, and a lifetime warranty on every piece.
All diamonds meet Kimberley Process standards, and the recycled metals they use go through a re-refining process that matches the quality of newly mined material. Concierge service stays with you from first conversation through delivery, and their Austin showroom is open by appointment if you want to see stones in person.
Brilliant Earth: Ethics-Forward Buying
Brilliant Earth built its brand around sustainability and ethical sourcing. They trace their diamonds to their origins and offer a selection of recycled metals. Their lab-grown diamond collection has expanded in recent years to meet demand from eco-conscious buyers.
According to The Knot’s 2025 Real Weddings Study, 52% of couples now choose lab-grown diamonds for their engagement rings, up 40% since 2019. Brilliant Earth has positioned itself well for this trend.
They maintain showrooms in several cities for those who want to try on rings before ordering. Their return window is 30 days, and they include complimentary resizing.
Ritani: See Before You Buy

This hybrid model appeals to buyers who want the convenience of online shopping with the reassurance of seeing the ring before committing. Their diamond selection includes GIA-certified stones, and their pricing is competitive.
Ritani offers free returns within 30 days and a lifetime warranty on all rings.
Vrai: Lab-Grown Specialists
Vrai focuses exclusively on lab-grown diamonds, grown in their own foundry powered by renewable energy. They control the entire production chain, which keeps prices lower while maintaining quality.
Their designs lean minimal and modern, favoring clean lines over ornate details. This aligns with one of the strongest 2026 engagement ring trends: refined minimalism with elegant proportions that highlight craftsmanship and stone quality.
A 1-carat lab-grown diamond from Vrai costs significantly less than a comparable natural stone. According to Zimnisky’s data from early 2025, an unbranded 1-carat lab-grown diamond runs about $845 compared to $3,895 for a similar natural diamond.
With Clarity: Try at Home
With Clarity ships replica rings to your door so you can see the setting and style on your hand before ordering. This removes much of the guesswork around how a ring will actually look in real life.
Their diamond selection includes both natural and lab-grown options, all with GIA or IGI certification. They offer a 100-day return policy, which is longer than most competitors, plus free lifetime warranty and cleaning.
Their concierge service pairs you with a gemologist who can answer questions and guide your selection.
Adiamor: Wholesale Pricing
Adiamor operates as a direct-to-consumer retailer, cutting out middlemen to offer wholesale pricing on diamonds. Their inventory includes over 100,000 certified stones with detailed specifications and images.
They specialize in classic settings and traditional designs rather than trendy styles. If you want a straightforward round brilliant solitaire at a fair price, Adiamor delivers without the markup you would find at department stores.
Their rings are made in the USA, and they offer free shipping, 30-day returns, and lifetime warranty on craftsmanship.
Taylor & Hart: Custom Design Collaboration
Taylor & Hart assigns a dedicated design consultant to every customer. You work together to create something custom, from choosing the stone to sketching the setting to approving 3D renderings before production.
This collaborative approach suits buyers who have a specific vision but need help executing it. The process takes 4 to 6 weeks, longer than some competitors, but the result is a one-of-a-kind ring tailored to your preferences.
They source conflict-free diamonds and offer both natural and lab-grown options. Free resizing is included for the first year.
Catbird: Delicate and Dainty
Catbird is known for delicate, understated designs that appeal to buyers who prefer fine details over large center stones. Their Brooklyn-based workshop produces each piece by hand.
Their signature style features thin bands, small stones, and minimal settings. They offer a selection of vintage-inspired pieces alongside contemporary designs. Pricing runs lower than many competitors because the focus is on craftsmanship rather than carat weight.
Catbird uses recycled gold and ethically sourced stones across their collections.
Mejuri: Affordable Everyday Luxury
Mejuri positioned itself as an accessible fine jewelry brand, pricing rings lower than traditional jewelers by selling directly to consumers and launching limited drops rather than maintaining massive inventory.
Their engagement ring collection is smaller than dedicated ring retailers but includes solid options for buyers working with budgets under $3,000. According to The Knot’s 2024 study, one-third of couples spend less than $3,000 on engagement rings, making Mejuri a viable option for this group.
They use 14k gold and ethically sourced diamonds, with free shipping and 30-day returns.
Clean Origin: Lab-Grown Focus
Clean Origin sells only lab-grown diamonds, positioning themselves as an affordable and environmentally conscious alternative to traditional retailers. Their pricing reflects the 50% to 70% savings typical of lab-grown stones compared to natural diamonds.
They offer a 100-day return policy and lifetime warranty. Their diamond selection includes IGI-certified stones across all popular shapes, from round brilliants to trending cuts like oval and pear.
Oval remains the top choice for millennials in 2026 due to its elongated, elegant look. Clean Origin stocks this shape heavily, recognizing the demand.
Angara: Colorful Gemstones
Angara specializes in colored gemstone engagement rings, offering sapphires, emeralds, rubies, and other stones alongside traditional diamonds. Their selection is among the largest online for non-diamond center stones.

Kay includes lifetime diamond and gemstone guarantees, free resizing, and a repair plan. Their selection favors classic designs over custom work.
Understanding the 4 Cs Before You Buy
The Gemological Institute of America created the 4 Cs in the 1940s as a universal standard for assessing diamond quality. Knowing these basics helps you compare stones across retailers.
- Cut affects brilliance, fire, and scintillation. A well-cut diamond interacts with light in ways that make it sparkle. This is considered the most important factor affecting appearance.
- Color grades how colorless a diamond is. Less color means a higher grade, and colorless diamonds are rarer.
- Clarity measures imperfections within the stone. Most inclusions are invisible without magnification, so this factor often matters less than cut or color for visual impact.
- Carat refers to weight. One carat equals 200 milligrams. Larger stones cost more per carat, but a smaller well-cut stone can outperform a larger stone with lower clarity.
Lab-Grown or Natural: Making the Choice
Both types share the same physical and chemical properties. They look identical and have the same hardness and durability. The main differences are price and resale value.
- Lab diamonds cost 30% to 50% less.
- A 1-carat natural round diamond of G color and VS2 clarity might run $6,000 to $8,000. The same specifications in a lab-grown stone range from $1,000 to $2,000.
- Natural diamonds generally retain value better over time, while lab diamonds may have less resale value due to broader availability.
- Both types receive certification from the GIA and IGI using the same grading standards.
Budget Guidance for 2025
The average engagement ring cost in 2025 is $6,504, though nearly two-thirds of buyers spend less than $6,000. The largest portion of buyers, 29%, spend between $2,500 and $5,000.
The old three-month salary rule no longer applies to how most people shop. A $5,000 budget buys a beautiful ring, especially if you prioritize cut over carat weight or consider lab-grown stones.
Certain shapes look larger per carat than round brilliants. Oval, pear, and marquise cuts create the illusion of greater size without the higher price.
Final Considerations
- Certification matters when buying online. Choose diamonds graded by GIA, AGS, or IGI. These labs provide accurate reports on cut, clarity, color, and carat.
- Check return policies before ordering. Look for free resizing, lifetime warranties, and responsive customer service. Contact the retailer with a test question to see how quickly and helpfully they respond.
- Give yourself at least 3 weeks before your proposal date to account for production and shipping.
Each retailer on this list serves different priorities. Match your priorities to the retailer that best meets them.
