Platinum 1.35ct Three Stone Diamond Ring – 1.03ct D IF IGI Certified Centre

£3,000.00

A timeless trilogy ring showcasing an exceptional quality centre diamond, this beautiful Platinum Three Stone Diamond Ring features a magnificent 1.03ct round brilliant cut diamond, graded D colour and Internally Flawless (IF) clarity.

The centre diamond is IGI certified, providing independent verification of its exceptional quality and characteristics.

Flanking the centre stone are two beautifully proportioned round brilliant cut diamonds weighing 0.16ct each, adding a further 0.32ct of diamond weight and bringing the total diamond weight of the ring to approximately 1.35ct.

All three diamonds are individually claw set, allowing light to enter the stones from multiple angles and creating beautiful brilliance across the finger. The graduated proportions naturally draw the eye towards the impressive 1.03ct centre diamond.

Crafted entirely in luxurious platinum, the ring has polished shoulders and a beautifully elegant profile that gives this classic three stone design a clean, contemporary finish.

Exceptional D Colour & Internally Flawless Clarity

The 1.03ct centre diamond is an exceptional quality stone. D is the highest colour grade awarded on the diamond colour scale, while IF – Internally Flawless – represents an exceptionally high level of clarity.

Combined with the ever-popular round brilliant cut, the result is a beautifully bright and impressive centre diamond with superb sparkle and presence.

Its quality is independently confirmed by an IGI certificate, giving additional reassurance of the diamond's grading and specifications.

The Meaning Behind a Trilogy Ring

Three stone rings are loved not only for their beautiful appearance but also for their romantic symbolism. The three diamonds are traditionally said to represent a couple's past, present and future together.

The two 0.16ct side diamonds beautifully frame the larger centre stone, creating a balanced and elegant design that makes this a wonderful choice for an engagement ring, anniversary ring or milestone gift.

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!
