Review
“Excellent experience, can’t believe the price I paid for my 1.67 carat, neither could the jeweler who was placing the diamond. Received an excellent price from Ritani (and Capital One extension found a 35% off promo). The diamond met high standards with no visible flaws and less than a nice 1 carat from Art of the Jewel. Shipping was fast and packing was sharp!”

Review
“I am really pleased with the engagement ring I purchased. I designed it through your “design your own ring” section and was worried the ring would look quite different from what I saw online but I was wrong. They do a good job of portraying what the ring will look like in actuality. The customer service is superb and truly 24/7, each member I talked to was very helpful and kind. Highly recommend buying through Blue Nile.”

Review
“Buying our loose engagement stone from Rare Carat was a great experience! We were nervous about buying a loose stone online but after doing a lot of research and with their 30-day guarantee, we decided to get our main stone from them, and it was absolutely stunning! We worked with a local jeweler to build the rest of the ring custom, but we saved over $5,000+ on the main stone by buying with Rare Carat compared to our local jeweler's prices for similar stones! Highly recommend them!”

Other Factors to Consider When Shopping for Engagement Rings
Picking out an engagement ring is a personal and emotional process, but you must keep a level head to stay on budget. To keep your feet planted, here are several considerations when shopping.
Price range
What people deem as affordable is subjective to their own finances. Try to determine a price range that aligns with your current money situation, and look for a brand that offers a selection that fits it.
Variety
Viewing different engagement ring styles can help you gauge what you like and don’t. Seek a jeweler who has a wide selection you can compare and contrast. It’s ideal if they can also walk you through the differences.
Customization
Customization is essential if you want to create a unique engagement ring for your future fiancée. Some jewelers have you start the process by choosing a setting, while others prefer you pick a diamond to base the whole piece on.
Shipping terms
Open and honest shipping terms are key, especially if you’re looking for affordable diamond engagement rings online. Look at the fees and whether there’s a return policy. There should also be warranties to protect your package.
How to Find the Perfect Diamond Engagement Ring
Are you overwhelmed by how to find a diamond engagement ring for the right price? Give yourself grace throughout the process and take it slow. Ideally, you start the search as early as possible so you don’t have to rush yourself and your jeweler. Here are some key notes to think about:
- Note down your partner’s preferences: Does your partner prefer silver or gold metals? What kind of stone size do they seem to like in rings?
- Understand the 4Cs: The cut, color, clarity, and carat weight of a diamond greatly influence its price. Figure out what your priorities and non-negotiables are for the stone.
- Set a budget: Once you’ve finalized your ideal specs for the 4Cs, it’s time to set a budget. Remember to be realistic when you’re outlining it.
- Browse and narrow down: Find brands in your price range and start a collection of listings. You can also get a quote for a customized ring. Aim for at least 10 options before narrowing it down and choosing the one you’ll propose with.
What Are the Best Affordable Diamond Ring Options?
