Size matters—but not the way you think.
At Elarion, we know choosing the perfect engagement ring isn’t just about sparkle—it’s about symbolism, personal taste, comfort, and creating a future heirloom. One of the most asked questions is:
“What carat size should I buy?”
Elarion Tip: Carat alone does not define brilliance—cut and proportions are the true stars.
Across the UK, the average engagement ring is around 0.9–1.2 carats. But “average” isn’t what we design at Elarion. We believe your diamond should reflect:
With lab-grown diamonds, you can often choose 30–50% larger stones within the same budget compared to natural diamonds.
| Carat Size | Approx. Diameter (Round Brilliant) | Look & Feel | Best For |
|---|---|---|---|
| 0.5 ct | ~5.2 mm | Dainty sparkle | Minimalist styles, stacking |
| 0.75 ct | ~5.8 mm | Elegant balance | Classic & understated |
| 1.0 ct | ~6.5 mm | Iconic size | Timeless choice |
| 1.5 ct | ~7.4 mm | Bold presence | Statement elegance |
| 2.0 ct | ~8.2 mm | Luxe brilliance | Glamorous, high impact |
| 3.0 ct+ | 9+ mm | Rare luxury | Show-stopping designs |
Elarion Advantage: With lab-grown diamonds, a 2.0ct stone is often priced similar to a 1.0ct natural diamond—making luxury more attainable.
Elarion Philosophy: Carat is just one chapter—your love story deserves the whole book.
Natural diamond prices rise sharply with each carat milestone (1.0ct, 1.5ct, 2.0ct). Lab-grown diamonds offer freedom:
At Elarion: Every diamond is IGI-certified for authenticity and quality.
