How to Design Your Dream Engagement Ring with Elarion

How to Buy an Engagement Ring: A Complete Step-by-Step Guide by Elarion

Decide on Your Budget

Why lab-grown diamonds make sense:

With Elarion, your money goes further. A lab-grown diamond of the same cut, colour, and clarity as a mined diamond typically costs 30–40% less, allowing you to either save money or choose a larger, higher-quality stone without stretching your budget.


Example: A 1.5 carat mined diamond might cost £9,000, while a lab-grown equivalent with identical brilliance could cost nearly half.

Understand the 4Cs of Diamonds

Diamonds are graded based on Cut, Colour, Clarity, and Carat—known as the 4Cs. Understanding these basics helps you balance beauty and value:

  • Cut: The most important factor, determining sparkle. A well-cut diamond reflects light brilliantly.
  • Colour: Graded from D (colourless) to Z (light yellow). The closer to colourless, the rarer it is.
  • Clarity: Refers to natural imperfections (inclusions). Higher clarity means fewer visible flaws.
  • Carat: The weight (and perceived size) of the diamond.

Elarion Advantage:

All our lab-grown diamonds are graded by IGI or GIA, ensuring you get transparent certification and exact grading.

Pro Tip: Prioritise Cut over Carat. A smaller but well-cut diamond will shine brighter than a larger, poorly cut stone.

Discover Your Partner’s Style

The perfect ring should reflect your partner’s personality. Pay attention to what jewellery they already wear:

  • Classic & Elegant: Consider a solitaire.
  • A Little Glamour: Explore halo designs.
  • Modern Minimalism: Sleek emerald or oval cuts are perfect.
  • Stand Out: A coloured lab-grown diamond or vintage-inspired setting might be ideal.

Elarion Tip: Unsure? Our design consultants can help you interpret your partner’s style and recommend settings they’ll adore.

Choose the Right Metal

The band of the ring defines the overall look:

  • Platinum: Hypoallergenic, durable, naturally white—premium choice.
  • White Gold: Sleek, versatile, pairs beautifully with brilliant diamonds.
  • Yellow Gold: Classic and timeless.
  • Rose Gold: Romantic and modern, with a soft pink hue.

At Elarion, we offer all major metals and can guide you based on lifestyle, skin tone, and design preference.

Select the Diamond Shape

The shape dramatically changes the ring’s personality:

  • Round Brilliant: Timeless and most sparkling.
  • Oval: Elegant, elongates the finger, very trendy.
  • Emerald: Vintage-inspired, sleek, sophisticated.
  • Princess: Modern square cut, stunning brilliance.
  • Pear: Unique, romantic, eye-catching.
  • Cushion: Mix of round brilliance and square elegance.

Trend Insight: Lab-grown diamonds make larger fancy shapes more accessible, so you can choose a bold cut without inflated pricing.

Find the Right Ring Size

Getting the size right is essential for the proposal:

  • Borrow a ring your partner wears on the same finger (left-hand ring finger).
  • Ask a close friend or family member discreetly.
  • Use Elarion’s online ring size guide.

Don’t stress—rings can usually be resized if needed.

Consider Customisation

An engagement ring is more than jewellery—it’s a symbol of your unique love story. Many couples today choose to customise:

  • Engrave initials, dates, or special words inside the band.
  • Add a hidden gem in a different colour.
  • Design a completely bespoke piece with our artisans.

At Elarion, we specialise in made-to-order lab-grown diamond rings, so you can design a ring as unique as your proposal story.

Verify Certification & Aftercare

Never purchase a diamond without certification. It ensures transparency, quality, and authenticity.
With Elarion, every diamond comes with IGI, HRD, or SGL certification, along with a lifetime warranty and professional aftercare services—from complimentary cleaning to resizing.

Plan the Proposal

Now that you’ve found the perfect ring, it’s time to plan the big moment. Whether it’s an intimate dinner, romantic getaway, or grand public proposal—what matters most is the love you share. The ring becomes the centrepiece of that memory, forever reminding you of that day.
