Diamond, Engagement Ring & Jewellery Guides | Jacob Mercari

A diamond tennis bracelet is one of the most timeless and versatile pieces of fine jewellery. Defined by a continuous row of individually set diamonds, it delivers elegant sparkle without feeling overly formal. It can be worn with an evening dress, a business wardrobe or a simple everyday outfit.

A custom engagement ring or fine jewellery piece is built to last for generations but only with the right care. Daily wear exposes gold, platinum, diamonds, and gemstones to lotions, chlorine, impacts, and everyday grime that can dull brilliance over time. This guide walks through the simple habits, cleaning methods, and storage practices that keep fine jewellery looking as brilliant as the day it was made.

Few pieces of jewellery are as versatile as diamond stud earrings. Elegant, understated, and easy to wear, they add the perfect amount of sparkle to everything from casual outfits to formal looks. Lab-grown diamond studs offer the same beautiful appearance as natural diamond earrings while often allowing you to choose a larger size or higher-quality diamond within your budget.

A pendant can be the most personal piece in someone's jewellery box a diamond passed down, a symbol chosen for a milestone, a custom design built around a birthstone or initial. But even the most beautiful pendant can look wrong on the wrong chain. Length changes everything: where the pendant sits, how it catches light, and whether it gets lost in a neckline or becomes the room's focal point.

A diamond pendant necklace is one of the most personal and versatile pieces of fine jewellery you can own or gift. It sits close to the heart, catches the light with every movement, and speaks volumes without saying a word. But before you fall in love with a specific stone, one question tends to stop people in their tracks: what’s the right diamond size?

Whether you’re shopping for yourself or searching for the perfect gift, knowing what to look for can make all the difference.

Here are the most common mistakes people make when buying diamond jewelry online—and how to avoid them.

When it comes to meaningful gifts, few things carry the same emotional weight as diamond jewelry. Whether it’s a birthday, anniversary, holiday, milestone, or a “just because” moment, diamonds have become one of the most powerful symbols of love, commitment, and lasting connection.

At Jacob Mercari, we love sapphires because they combine timeless beauty with everyday practicality. Whether you are designing a custom ring, choosing a meaningful pendant, or looking for a colourful gemstone piece you can wear daily, sapphire is always a beautiful choice.

At Jacob Mercari, we’ve built our studio on the belief that the most meaningful jewellery tells a story. Birthstones are one of the oldest ways to do exactly that. Whether you’re designing a custom engagement ring, a gift for someone you love, or a personal piece for yourself, choosing a gemstone tied to your birth month adds a layer of intention that a diamond alone simply cannot replicate.

Thinking about buying an engagement ring at a retail chain? Discover why choosing a bespoke jeweller like Jacob Mercari gives you better diamonds, more value, and a ring that's truly one of a kind.

Fine jewellery has quietly, then suddenly, become the preeminent language of taste, ambition, and identity. Not costume. Not trend. Jewellery that endures that was chosen with intention, worn with conviction, and passed down with meaning.

At Jacob Mercari, we have always believed that a truly exceptional piece of jewellery is not an accessory. It is a declaration.
