Platinum 0.40ct Natural Diamond Solitaire Ring

£1,800.00

Elegant, timeless and beautifully refined, this Platinum Natural Diamond Solitaire Ring is a true celebration of classic jewellery design. Featuring a 0.40 carat natural round brilliant-cut diamond, this exquisite ring is handcrafted to showcase the exceptional beauty and brilliance of one perfectly chosen diamond.

The diamond is securely held within a classic four-claw setting, allowing light to enter from every angle and maximise its natural sparkle. This traditional design has remained the world's most popular engagement ring style for generations, admired for its simplicity, sophistication and enduring elegance.

The centre stone weighs 0.40 carats and has been carefully selected with a G colour and SI2 clarity. Offering exceptional brilliance and fire, this natural diamond creates a stunning focal point while representing excellent value within a beautifully handcrafted platinum setting.

Crafted in solid platinum, the band offers both luxury and durability. Platinum is naturally white, exceptionally strong and highly resistant to everyday wear, making it one of the finest precious metals for engagement rings designed to be treasured for a lifetime. Unlike white gold, platinum retains its naturally white appearance without the need for rhodium plating.

The slender, gently rounded band creates an elegant profile that allows the diamond to remain the centre of attention while ensuring exceptional comfort for everyday wear. Its timeless design pairs effortlessly with a wide range of wedding bands, making it the perfect choice for those seeking a traditional engagement ring with lasting appeal.

Every engagement ring created by Robert Bicknell Fine Jewellery reflects generations of craftsmanship, attention to detail and a passion for creating jewellery that marks life's most meaningful moments. Whether chosen for a proposal, anniversary or special celebration, this solitaire ring is designed to become a treasured family heirloom.

For those wishing to create something more personal, this design can also be commissioned with different diamond sizes, alternative diamond qualities or in a choice of precious metals including 18ct yellow gold, 18ct white gold and 18ct rose gold.

Robert did a magnificent job in repairing and resizing my wedding band and engagement ring which had been tucked away in a drawer for years as I wasn't sure to whose hands I could trust them. I definitely found the right man for the job and I am so pleased with my rings that are like I first wore them 20 years ago. It wasn't an easy repair as platinum can be temperamental but he addressed the repair with great skill and professionalism. I can thoroughly recommend Robert to handle your beloved jewellery.

I had such a great experience with Robert. I came to him with one of my mum's favourite rings, which was broken in two places and missing a stone; I did not think it could be fixed, especially as it was quite an unusually constructed and delicate ring. After discussing with Robert, he advised that he could do it. The result was just astonishing, it looked brand new! My mum was so happy to be able to wear her ring again, we are so happy with Roberts work. He was professional, the time estimate on completing the work was accurate, the work was impeccable; cannot recommend him enough. Thank you so much!

I had an excellent experience with Robert Bicknell Fine Jewellery. Robert enlarged my late grandfather’s dress ring, and the result was amazing. The craftsmanship was flawless — the ring looked fantastic while still preserving all its original character and sentimental value. He also renewed the clasps on two of my gold necklaces and, along with other items I’d left with him, gave them all a thorough clean, bringing back their shine. His professionalism, attention to detail, and genuine care for his work really stood out. I couldn’t be happier with the result. Highly recommend!
