South Africa’s Premier Custom Hand Crafter of Fine Jewellery
Every OgilvieGems piece begins with a vision. Some clients arrive with a complete design. Others arrive with only a photograph, idea or feeling. From custom engagement rings and wedding bands to heirloom remodelling and fine jewellery commissions, each piece is crafted around the individual wearing it.

Ogilvie is not simply a brand name. It is our surname, our reputation and our legacy.

Lab-Grown Diamond Engagement Rings
Lab-grown diamonds are real diamonds created from carbon using advanced growth methods such as HPHT and CVD. They are chemically and physically identical to mined diamonds and allow many clients to achieve larger or higher-specification stones within a more comfortable budget.
OgilvieGems works extensively with IGI-certified and selected premium laboratory-grown diamonds.
Natural Mined Diamond Rings
Natural mined diamonds remain one of the most traditional choices for engagement rings and fine jewellery. For mined diamonds, OgilvieGems generally prioritises GIA-certified stones unless otherwise requested.
Every mined diamond is sourced based not only on certification, but also overall beauty, proportion, brilliance and value.
Moissanite Engagement Rings
Moissanite is its own gemstone entirely. While visually similar to diamond, moissanite is composed from silicon carbide rather than carbon. Many clients love moissanite for its brilliance, fire and affordability.
Most people struggle to visually distinguish moissanite from diamond without direct comparison or specialised knowledge.
Jewellery Remodelling & Heirloom Redesign
Many clients choose to redesign inherited jewellery, family diamonds or older gold pieces into something more wearable and personal. Existing stones and gold may sometimes be reused depending on structural suitability, design requirements and metal condition.
Jewellery remodelling allows sentimental pieces to continue into a new generation while preserving emotional significance.
Custom Wedding Bands
Wedding bands are crafted to complement both lifestyle and engagement ring structure. From classic polished bands and comfort-fit styles to diamond eternity bands and shaped wedding rings, every band is designed around proportion, comfort and long-term wearability.
