How Big Is a 1 Carat Diamond Ring Really?

How Big Is a 1 Carat Diamond Ring Really?

Many people equate carat with size, but in reality, carat is a measure of weight — not physical dimensions. A standard round 1 carat diamond typically measures around 6.4 mm to 6.5 mm in diameter, assuming it's well-cut. Size Differences Based on Cut: Round Cut: ~6.4 mm diameter Princess Cut: ~5.5 mm x 5.5 mm Oval Cut: ~7.7 mm x 5.7 mm (appears larger) Emerald Cut: ~6.5 mm x 4.5 mm The diamond cut also affects how big it looks on the finger. A well-cut diamond reflects more light, making it appear larger and more brilliant. At Kahaan Jewels, we guide customers through side-by-side comparisons to help them select the best cut that complements their hand size, finger shape, and style preferences.

What Is the Current Value of a 1 Carat Diamond?

One of the most important aspects to consider when shopping for Diamond Engagement Rings is price. In 2025, the price of a 1 carat diamond ring in the UK can vary greatly depending on the Four Cs: Carat Weight Cut Quality Colour Grade Clarity Grade Average Price Ranges: Natural Diamonds: £3,000 to £7,000+ Lab-Grown Diamonds: £1,500 to £3,500 Other factors include brand reputation, ethical sourcing, and certification. At Kahaan Jewels, all diamonds come with GIA or IGI certification and are handpicked by gemologists. We maintain complete transparency on origin and grading.

Tips for Buying the Perfect 1 Carat Engagement Ring

When you're ready to purchase a 1 carat ring, keep the following expert tips in mind: 1. Focus on the Cut The cut has the greatest impact on a diamond’s sparkle. Even a flawless diamond with a poor cut won’t shine as brilliantly as one with excellent proportions. 2. Don’t Ignore Fluorescence Some diamonds have fluorescence, which can affect appearance. Ask for expert advice when evaluating such stones. 3. Choose the Right Setting The setting affects how big the diamond looks. A halo setting, for instance, can make a 1 carat diamond appear closer to 1.5 carats. 4. Ask About Upgrade Policies Some buyers prefer to upgrade their diamonds over time. Kahaan Jewels offers an upgrade program that allows you to trade in your diamond later. 5. Think Long-Term You’re not just buying a ring — you’re investing in a piece of jewellery that may become a family heirloom. Ensure it comes with certification, warranty, and maintenance support.

Why Spring Is the Perfect Time to Rethink & Refresh Your Jewellery

pring is a time of renewal - and not just for nature. As the days get longer and warmer, it's natural to feel like switching things up: swapping heavy knits for lighter layers, trading boots for sandals, and maybe even giving your jewellery collection a bit of a refresh too. After months of winter hibernation (both literally and sartorially), spring is the perfect season to revisit your style. It doesn't have to mean buying a whole new wardrobe: simply adding a few fresh pieces or trying new outfit and jewellery combos can make everything feel lighter, brighter, and more 'you' again. I'm an Australian jewellery designer and maker, and I've been creating jewellery for over 25 years. One thing I know for sure? Jewellery is one of the easiest and most joyful ways to express your style - especially at this time of year. Whether you're looking to fall back in love with pieces you already own or you're ready to treat yourself to something new, this guide is here to help you embrace the season in style. We'll explore how to style your jewellery for spring, what's trending this season, and how to make conscious, beautiful choices that reflect who you are. We'll also share some of our favourite spring-inspired pieces and gift ideas. Ready to feel inspired? Let's dive in.
