Description
This is a 9ct white gold engagement ring set with 0.39 carats of princess-cut diamonds in a trilogy layout, each stone secured in a four-claw setting.
The stone
Three princess-cut diamonds are arranged in a graduated trilogy, with the centre stone flanked by two smaller stones. The square-cut profile of the princess shape delivers brilliant fire and sharp, modern lines. Together the three stones total 0.39 carats. Each diamond is held in a four-claw setting that lifts the stone and allows light to enter from every angle, maximising brilliance while keeping the profile low and practical for everyday wear.
Setting & band
The shoulders are pavé-set with small round diamonds that taper toward the back of the band, adding continuous sparkle without overwhelming the trilogy centrepiece. A fine milgrain edge runs along both sides of the pavé shoulders, lending a vintage-inspired texture and framing the stones with precision. The band itself is slim and tapered, with a court (rounded) profile that sits comfortably inside the finger. The polished finish across the 9ct white gold reflects light cleanly and complements the white brilliance of the diamonds.
The metal
The ring is made in 9ct white gold, a durable alloy that balances strength with a bright, neutral tone. It wears well with daily handling and maintains its appearance over time.
Who it suits
This engagement ring suits someone drawn to classic three-stone symbolism with a modern edge. The princess-cut stones and pavé detailing give it a contemporary feel, while the trilogy layout and milgrain edge nod to tradition. It pairs well with a plain or pavé wedding band and reads as elegant without being oversized on the hand. Explore more styles in our collection of diamond rings, or read our diamond jewellery guide for advice on cuts and settings.
Wear & sizing
The ring is supplied in size M and can be resized to fit. Engraving is available to personalise the inside of the band, and a valuation certificate can be arranged. If you'd like to adjust the design or metal, the ring can be made to order to your specifications.
See this engagement ring in person at our Mall of the South and Greenstone showrooms.

FAQ
Yes, the ring is supplied in size M and can be resized by our jewellers to fit your finger. We recommend booking an appointment at either of our showrooms so we can measure your finger accurately and discuss any adjustments needed.
The small pavé diamonds are secure in their settings, but we recommend removing the ring during heavy manual work or when using harsh chemicals. Have the settings checked during routine maintenance to ensure the claws remain tight.
9ct white gold maintains its colour naturally. With everyday wear, the polished finish may develop a soft patina; a professional polish will restore the original brightness.
A plain court band or a pavé-set band will sit neatly alongside this ring. Because the shoulders are pavé-set and taper toward the back, most wedding bands will align comfortably. We can show you pairing options in our showrooms.
Yes, engraving is available and is a popular way to personalise an engagement ring. Visit our engraving page or speak to our team about character limits and font options.
Yes. The four-claw settings hold each princess-cut stone securely, and the court band profile is comfortable for all-day wear. The 9ct white gold is durable enough for everyday handling, though we recommend removing the ring during activities that might knock the stones.
Warranty
There is no formal manufacturer warranty on jewellery, but Cassims & Co. guarantees its workmanship: if a manufacturing defect or craftsmanship issue appears, we will repair or replace the piece at no charge. Normal wear, accidental damage, lost stones from knocks, and alterations by third parties are not covered.
Professional cleaning, inspection, claw checks and resizing are available at either showroom.
Care guide
- Remove the ring before cleaning, gardening, exercising or working with tools to protect the pavé settings and prevent knocks to the princess-cut stones.
- Clean the ring at home with warm water, a few drops of mild detergent and a soft brush; rinse thoroughly and dry with a lint-free cloth. Pay attention to the pavé shoulders where dirt can collect.
- Store the ring separately in a soft pouch or lined compartment to prevent the diamonds from scratching other jewellery.
- Avoid exposing the ring to chlorine, bleach and other harsh chemicals, which can discolour the 9ct white gold and weaken the settings over time.
- Have the ring inspected by a jeweller every twelve months to check the claws and pavé settings, and to professionally clean and polish the metal.
- The milgrain edge detail may wear smooth with heavy contact; a jeweller can re-apply the texture during servicing if desired.
