Expertly designed and created with exquisite care, every H. Sena piece is a timeless work of art that stands apart from changing fashions of the day. We work with our clients to bring to life beautiful, unique, bespoke personal jewellery; theirs to own, forever.

We use only 18-karat gold, white gold, and platinum – authentic precious metals, forged solid in every ring, necklace, bracelet, pendant, earring and wedding band. We carry and use only premium quality diamonds and coloured stones, individually selected for cut, colour, clarity and carat weight from the finest stock available. Our experienced local artisans thoughtfully sculpt, arrange and set every item by hand with the utmost attention to detail for a perfect masterpiece that withstands the test of time.

As part of our ongoing commitment to authenticity and sustainability, we buy only conflict-free GIA certified diamonds, rubies, sapphires, emeralds and birthstones from ethical suppliers committed to upholding human rights and protecting the environment.

Craftmanship Craftmanship


When considering gemstones, we base our choices on the 4Cs - cut, carat, clarity and colour. These are the objective and universally recognised standards of diamond quality.

  • colour


    The colour classification scale grades every gem on hue and intensity. Unusually, white diamonds are graded on their lack of colour, as clear and bright stones are generally preferred. Coloured diamonds are additionally appraised according to their rarity and demand in fashion, with red diamonds being the most rare and thus, the most expensive.

  • clarity


    All precious stones have individual, naturally occurring ‘birthmarks’. Most are microscopic and have minimal effect on the jewel’s appearance. When birthmarks are invisible even under 10x magnification, the gem is considered ‘flawless’.

  • carat


    The weight of a gemstone is measured in carats, a highly precise system of determining the exact mass, and thus the value, of a stone. Contrary to common misunderstanding, carats do not directly reflect the size of a stone, but are one of several factors influencing how big your gem may appear.

  • cut


    The cut of a gem determines how light reflects off each of its surfaces (facets). Stones are cut to precise mathematical proportions, allowing as much light as possible into and around the stone. A well-cut diamond will flash and sparkle in the light.

We create thoughtful customised and personal items, based on your ideas, which will be yours, exclusively, forever.

Home Care

Fine jewellery is meant to last for generations. All pieces set with precious gemstones can be washed in warm, soapy water and cleaned with a soft toothbrush to remove any oils, grime and dirt that impact their brilliance and shine. Rinse these pieces well under running water, and dry with a soft cloth. Always ensure your sink is plugged before you begin cleaning, as jewellery can slip easily from soapy hands.

Opt for a case or individual storage bag lined with soft fabric, and ensure your jewellery is dry before you put it away. As metals and stones may rub together in storage, it is important to keep your pieces separated to avoid scratching and wear. Jewellery can also become scratched and worn from use. Where possible, avoid wearing different metals next to each other, as harder metals may damage their softer companions. Keep your jewellery in a safe, dry place when doing rough work, as any knocks, rapid changes in temperature, and contact with chemicals and chlorinated water can cause damage to metals, mounts and gemstones.

After Sales Care

When your new piece is complete, we’ll make an appointment for you to come pick it up. We can also arrange a reminder call, if your appointment is longer than a few days away.

With proper care, fine jewellery should last beyond a lifetime. We can help you professionally maintain every piece of jewellery, and recommend a visit to the H. Sena store every six to twelve months in addition to your regular home care routine.

We’ll inspect each piece and gemstone under a loupe for wear and tear – which does happen when you’ve kept a wedding band, engagement ring or favourite earrings on every day. We can then make adjustments and repairs, and get it polished and plated to make it look brand new once again.
