Fine Jewellery Guides & Inspiration | Jacob Mercari

A tennis necklace creates a line of sparkle, while a solitaire pendant draws attention to one diamond. Compare their look, fit and buying considerations to choose the necklace you will love wearing.

Natural fancy colour diamonds combine the rarity of a diamond with a colour formed by nature. The most remarkable examples have sold for tens of millions of dollars at auction. Their prices reflect more than carat weight: colour, rarity, clarity, cut, provenance and the strength of collector demand all contribute.

A fancy coloured diamond is valued for the colour it shows face-up. Whether it is natural or laboratory-grown, a gemmological laboratory examines the diamond and documents its colour and identifying characteristics. The grading process helps you understand what you are shopping for, how the colour is described, and whether the diamond’s colour is natural, treated, or associated with laboratory growth.

Here are the most important things to consider before buying an engagement ring online.

Instead of filling your jewellery box with pieces you only wear once in a while, think of fine jewellery the way you might think about a great wardrobe: start with a few beautiful essentials, choose pieces that work together, and invest in designs you will genuinely enjoy wearing.

Trying to choose between a 1, 1.5 and 2 carat engagement ring? Compare how each size looks, how shape and setting affect its appearance, and which option best suits your style, lifestyle and budget.

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.

Platinum and gold are both beautiful, long-lasting precious metals, but each offers distinct advantages. Whether you prefer the naturally white appearance of platinum, the warmth of yellow or rose gold, or the polished elegance of white gold, understanding the differences can help you choose a ring that complements your style and lifestyle.
