Individual masterpieces - Rings by RenéSim

Masterpiece Mother-of-Pearl Ring

Masterpiece: Ring set with spinel gem

This very special ring was created in close consultation with the customer. RenéSim was proud to create two very special pieces for this customer: a dragonfly pendant set with mother-of-pearl, and this ring, which also features the shimmering material. The 1.5-carat spinel gem that adds the finishing touch to the wide ring band was the customer's own.

Individual creations by RenéSim

The iridescent shimmer of mother-of-pearl and its rainbow gleam enhance the radiance of the red spinel still further. The exquisite material was set into the broad ring in individual pieces, tailored to the curves of the white-gold ring band. The result was this beautiful and exceptional ring.

Masterpiece Ebony Ring

Masterpiece: Diamond and ebony ring by RenéSim

This unique ring contrasts a brilliant-cut 0.75-carat diamond in colour D and clarity IF with an elegant ebony setting. The customer asked for a ring in a contemporary design, crafted from new and unusual materials. This exceptional piece combines the three materials – wood, metal and mineral – into a stunning whole.

Individual jewellery – designed by you

Ultra-fine platinum polished to a high gloss was chosen for the band of this ring. The weight of the metal creates an extremely comfortable feeling in wear, unlike a ring made purely from wood. The virtually black ebony was milled into the ring shape from a single piece and smoothed to create a sophisticated, elegant effect.

Masterpiece Emerald Ring

Glowing green emerald and glittering gold

The individual elements of emerald, diamonds and gold are combined in a piece of jewellery that embodies the purest luxury. The green octagon-cut gem is held in an elegant bezel setting; the ring band itself features two side brilliants. The gold further highlights the intensely glowing shade of the emerald.

The ring blends cool, classic design with an elegant delicacy, combining the cool elegance of the glowing green emerald with the soft warmth of gold. The clean, clear lines of the ring band highlight the classic style of the piece and avoid frivolity.

Masterpiece Brilliant Ring

Platinum ring with brilliant – a ring of harmonious beauty

Perhaps the most impressive feature of this stunning broad ring of superfine platinum is its superb diamond. The brilliant-cut gem in colour River D is flawless, with a cut and proportions of exquisite quality. Weighing 2.7 carats, it is immensely valuable.

An elegant backdrop for a brilliant-cut gem

RenéSim's customer bought the extremely valuable stone as an investment, but decided to use it in a ring to create a wearable piece. The diamond was placed in an extra-slim setting for maximum security and protection against any damage which might occur in wear.

Masterpiece Spinel Ring

Masterpiece with outstanding attention to detail

This custom piece designed to the customer's wishes is certainly 'edgy', and very far from being smooth and sweet. The design has a cool, highly technical feel. The customer explicitly requested that the ring should not be too feminine or soft, but should contrast with another piece of jewellery owned by the customer. This effect was achieved by creating an angled, edged effect to highlight the technical precision of the design.

Individual wishes – customised creations

The ring is crafted from palladium with a matte, slightly darker outer finish and polished interior for superb comfort. The matte ring band is designed to avoid distracting the eye from the radiance of the 0.5-carat ruby, with its subtle pinkish tint, while avoiding an overly feminine effect from the coloured gemstone.

RenéSim's experience and our vast expertise in jewellery design is at your service for the creation of your personal ring. As already mentioned, this expertise is particularly important in deciding on the colour combination, making the associated choice of metal and selecting the perfect gemstone, and harmonising the individual elements of the ring with one another.
