    "When I made my first solitaire ring in a small London workshop, I didn’t know it would start a journey that would touch so many love stories. But every ring we've made since carries that same promise: something honest, elegant, and everlasting."

Why Choose a Classic Solitaire Engagement Ring?

There’s a reason the solitaire engagement ring has stood the test of time. It’s the epitome of grace and simplicity, allowing the diamond to take centre stage. This style is revered across generations and cultures for its iconic symbolism and timeless aesthetic.

  • Symbolism That Speaks Volumes: A single diamond symbolises one love, one commitment, and one incredible journey together. It speaks of unity, strength, and enduring affection.
  • Universally Recognised: Solitaire rings are instantly recognisable and widely loved. Whether you’re proposing in a London café or on a beach in Greece, this ring style delivers the message of love loud and clear.
  • Elegant Minimalism: With no side stones or distracting embellishments, the solitaire design allows the diamond's natural beauty to shine through, making it the ultimate expression of refined taste.
  • A Lasting Investment: Classic solitaire designs tend to hold their value better than trendy styles. When chosen with quality in mind, they are not just a romantic gesture but a smart investment.

Customer Love: "I wasn’t sure what ring to pick, but the team helped me customise a solitaire exactly how I imagined. When I proposed, she cried. The diamond sparkles like our future!" — James B., Manchester

Choosing Your Metal — What Matches Their Style?

Yellow Gold Warm and rich Traditional, enhances diamond contrast Lovers of timeless, vintage charm
Rose Gold Blush pink hue Romantic, modern vintage Stylish, sentimental personalities
Silver Bright but softer Fashion-forward, lower cost Not ideal for lifetime wear but good for occasional rings

Diamond Size — What Carat Is Right?

Let’s debunk the myth: bigger is not always better. The best diamond is the one that’s beautifully balanced in cut, clarity, and proportion to the wearer’s hand.

  • Most Popular Sizes: 0.75 to 2 carats
  • Sweet Spot: A well-cut 1-carat diamond delivers presence without overwhelming
  • Pro Tip: Focus on brilliance. A 0.90ct ideal-cut stone can outshine a 1.00ct poorly-cut diamond

Hand size, finger shape, and even daily lifestyle should guide your decision. We’re here to advise you, every step of the way.

Understanding the 4 Cs – The Sunshine Diamonds Way

We know diamonds. Let us make the 4 Cs easy to understand:

  • Cut – The sparkle factor. The better the cut, the more brilliance. Prioritise this above all.
  • Colour – Diamonds range from colourless (D) to yellowish (Z). G-H-I are great value for white settings.
  • Clarity – Look for “eye-clean” diamonds. VS1 or VS2 offer great clarity without the premium price.
  • Carat – A measure of weight, not just size. A smaller carat can still look bigger with the right shape and cut.
