Frequently Asked Questions

General Info

Why choose BlumLux for your custom engagement ring?

The process of finding the perfect engagement ring can be stressful, even overwhelming, at times.

We get it. It’s hard to figure out what engagement ring your future spouse will want. If that isn’t stressful enough, trying to find the right ring at the right price online can be even more time-consuming and frustrating.

What if you could create a custom engagement ring with the satisfaction of knowing your purchase had the lowest possible ecological and ethical impact?

BlumLux offers a brilliant selection of Pure-Grown diamonds for custom engagement rings at a price you can afford, coupled with a smooth, customized online experience.

Yes, that’s right - no salespeople working on commission or trip to actual jeweler location required!

We focus on the small details that make a big impact.

Bottom line: Because of our state-of-the-art digital ordering system, clients are often able to afford a customized engagement ring with a larger diamond for the same price than if they purchased from another online or brick-and-mortar jeweler.

Who is Nick Blum? How do I know he’s not a bot?

Nick is a real person -- trust us on that. From the initial design to final delivery, Master Jeweler Nick Blum sets himself apart by taking a “hands-on” approach to the entire process. As a GIA-certified graduate, you will benefit from his years of experience when creating an affordable custom engagement ring.

Every single diamond from BlumLux is hand-selected to make sure it is the perfect fit for your partner, setting, and budget - how many other online jewelers can say the same?

What metals does BlumLux use?

BlumLux works with several different metals to ensure your engagement ring and wedding bands, as a set or separately, are uniquely you! Choose the metal that suits your partner best: white, rose, or yellow gold (14K or 18K), or platinum.

Master Jeweler Tip: a platinum wedding band is stronger and more durable than a white or rose gold wedding band - it doesn’t lose its luster over time.

Does Blumlux offer a Lifetime Warranty?

All BlumLux engagement rings and wedding bands are backed by a Lifetime Warranty on any manufacturing defects. If your ring purchase has been found to have a manufacturing defect, BlumLux will repair or replace the item free of charge. The lifetime warranty is subject to the following conditions:

  • The warranty does not include defects from normal wear, including plating wearing off, scratches/scuffs, damage due to negligence or accidents, chips in diamond.
  • Any engagement ring or wedding band found to have a manufacturing defect will be repaired or replaced at the sole discretion of BlumLux.
  • The warranty may be void if a BlumLux ring setting, mount, or design is altered by an unauthorized third-party.

BlumLux reserves the right to determine whether the problem is due to a manufacturing defect or a result of normal wear and tear.

Does BlumLux offer gift certificates?

Sorry, BlumLux doesn't offer gift certificates.

Engagement Rings

How does purchasing a custom engagement ring from BlumLux work?

BlumLux uses a five-step purchasing process, starting with a questionnaire to help Master Jeweler Nick Blum create the custom engagement ring your partner will love.

Once you create an account, you’ll be able to choose from our collection of brilliant engagement ring designs, or you can create your custom engagement ring. That includes the setting, size, metal, and your diamond budget.

After selecting your setting, you’ll tell us the preferred price range for your diamond. Master Jeweler Nick Blum will hand-select three stunning options from which you may choose.

From there, you will make the initial payment on the ring setting. Within 2-3 business days, you will receive an email with your diamond selections. Each one of the hand-selected Pure Grown diamonds comes with a comprehensive overview on cut, clarity, shape, size, and price. You will also receive notes from his inspection of the stones to help you make the best decision.

After reviewing your options, the final step is to select what diamond will complete your custom engagement ring. Once you’ve made your choice, you make the final payment on the ring, and we get to work. Your BlumLux ring will then be crafted and shipped to you in 2-4 weeks via insured mail.

Can I purchase a ring directly from the BlumLux catalog?

We’ve spent years honing our brilliant collection of engagement rings and wedding bands - feel free to choose from one of our existing designs! Simply select the ring you want, choose the correct ring size, and checkout. Turnaround time is 2-4 weeks, with free shipping on all orders. BlumLux will notify you via email when your ring ships.

What diamond cuts does BlumLux offer for engagement rings?

BlumLux offers these distinct diamond cuts:

  • Round
  • Princess
  • Cushion
  • Radiant
  • Pear
  • Oval
  • Marquise
  • Emerald
  • Asscher
What ring settings does BlumLux offer?

One of the perks of purchasing from an independent jeweler is being able to create something unique, including the setting. Each BlumLux ring setting available for purchase on our website has been personally designed by Nick Blum. These one-of-a-kind ring settings are not available anywhere else. Your partner will appreciate the distinct design that sets the ring apart from the typical engagement ring sold by chain jewelers.

I found a picture of the ring I want. Can BlumLux create a custom engagement ring?

Yes! Creating custom engagement rings for clients is our specialty. For a price quote, please send a photo of the desired ring along with a detailed description to info@blumlux.com. BlumLux will provide a price quote within 24 hours whenever possible.


Master Jeweler Tip: it’s great to have an idea of what you want, but remember to be open to suggestions from your jeweler - collaboration will make your partner’s custom engagement ring all that much more special!

Can I purchase multiple engagement rings, compare them, and then return the ones I don’t want?

We do not recommend this approach. BlumLux offers you the ability to purchase a customized engagement ring completely online at an affordable cost so that you can create one perfect ring for your perfect match. Read our return policy.

How much should I spend on an engagement ring?

The industry has pushed the idea of an engagement ring costing between 2-3 months’ salary. While this can be a good starting point, BlumLux believes that it’s more important to establish a manageable engagement ring budget when making this decision.

No need to start off your new marriage in debt when you can maximize your purchasing power with one of our Pure-Grown diamond engagement rings. BlumLux will work within your budget, no matter what you plan to spend on the engagement ring.

I don’t know my partner’s ring size. How do I figure out what it is while keeping it a secret?

Don’t despair! Here are a few ideas to help you learn your partner’s ring size (without ruining the surprise).

  • Ask your partner’s friends or family if they know their ring size.
  • Sneak a peek into their jewelry box and borrow one of their rings. Then, download our BlumLux sizing guide and use it to find the correct size.
  • If you want to find out the ring size directly from the source, ask in a very subtle, smooth way. We suggest pretending that you are going to buy a ring for your mom/sister/aunt/niece etc. whose hands are similar in size. Casually ask what their ring size is for reference.
What if the ring doesn’t fit after I buy it?

If the ring doesn’t fit correctly after purchasing, you have two options:

  1. BlumLux offers free ring resizing through the first year after purchase. Just send the ring back to us and we’ll take care of it!
  2. Contact your local jeweler. Resizing is generally inexpensive and quick.

Purchases

Do I pay for the entire engagement ring purchase up front?

It depends on the purchase type.

For custom engagement rings, you pay for your BlumLux engagement ring in two installments.

  • The first installment is expected after selecting the setting

For catalog engagement rings, you are expected to pay for the entire purchase at checkout because you are choosing the setting and center stone in the same transaction.

After selecting your BlumLux custom engagement ring setting, you will be prompted to pay the initial ring down payment.

Pure Grown Diamonds

What is a Pure Grown diamond?

A Pure Grown diamond is grown in a lab and has zero ecological or ethical issues. Every Pure-Grown diamond used by BlumLux is personally inspected by Master Jeweler Nick Blum to ensure they meet his high standards.

How is a Pure Grown diamond different from a mined diamond?

The only difference is in the source of the stone itself. Pure Grown diamonds are created in a lab, while mined diamonds often come from war-torn parts of the world and have a negative impact on the local population and the environment. Mined diamonds also require extra physical labor for extraction, which drives up their cost (without adding value).

Can you tell the difference between a mined diamond and a Pure Grown diamond?

No! BlumLux lab-grown diamonds are 100% carbon with the same properties as mined diamonds, including grading. For all practical purposes, Pure-Grown diamonds are identical to mined diamonds in their physical and optical properties - BlumLux engagement rings are just as dazzling, with the bonus of being able to afford a better diamond for the same price!

Why does BlumLux only use Pure Grown diamonds?

At BlumLux, we are committed to leaving the planet a better place than when we found it. That's the main reason we exclusively source Pure Grown diamonds instead of mined diamonds. Pure Grown diamonds are certified, conflict-free, and environmentally-friendly. Pure Grown diamonds also don’t require extraction from the Earth, making them more affordable.

Pure Grown diamonds are the only sustainable choice currently available to consumers. BlumLux is committed to doing our part to help restore balance to biodiversity and the environment.

Mined diamonds represent more than seven times the level of environmental impact when compared to lab-grown diamonds. Pure Grown diamonds have a far less direct impact on the environment than mined diamonds. They are created in a technologically-advanced facility that uses modest amounts of energy. They also don’t undermine the future sustainability of natural ecosystems.

Pure-Grown diamonds are certified by the same leading independent gemological labs, using the same criteria and grading standards as mined diamonds. Every lab-grown diamond used by BlumLux is also laser-inscribed with the unique, corresponding grading report number to properly identify your lab-grown diamond and confirm its guaranteed origin (conflict-free).
