A guide to crafting and selecting fine pieces

These gemstones occur naturally in nature and are mined from the ground. The traditional classification of natural gemstones goes back to the ancient Greeks, who created a distinction between precious and semi-precious stones. Precious stones include emeralds, rubies, sapphires and diamonds, with all other gemstones falling into the latter category. In their purest form, natural gemstones are translucent with colour, with the exception of the colourless diamond. 


Lab - created gemstones are man-made as opposed to being mined from the ground like their natural counterparts and as a result, are free from the destructive environmental effects of mining. Lab - created synthetic gemstones have an identical composition and chemical structure to natural gemstones. They also carry the same colour, hardness and brilliance. Fine jewellery made with lab-created gemstones has less environmental impact and provides a responsible option.

Precious metals are used in fine jewellery both for their rarity as well as for their structural integrity. At Helene, we use gold, sterling silver, gold plating and vermeil to create our timeless pieces. Learning the differences between these metals gives you the knowledge to understand the value of your pieces and more significantly, which you prefer for different occasions.

Sterling silver 

All our silver jewelry is crafted from Sterling Silver, a composition of 92.5% pure silver and 7.5% alloy. This combination not only preserves the lustrous beauty of precious metal but also imparts enhanced strength and durability. While Fine Silver, in its pure form, is too soft for fine jewelry designs, our Sterling Silver pieces ensure enduring quality and timeless beauty.Each piece undergoes meticulous craftsmanship that adds a touch of sophistication to every occasion. Sterling Silver may tarnish when exposed to various elements such as salty air, chlorine, humidity, perspiration, cosmetics, household bleach, and other strong chemicals. To preserve its brilliance, we recommend storing your fine jewelry in a safe, dry place.


In its natural form, gold is yellow in colour and mined in many different ways. Pure 24 carat gold is so soft that it is rarely used in jewellery. The process of alloying, or mixing other metals with pure gold, gives malleable gold added durability so it can be used easily when creating fine jewellery, resulting in different levels of purity. 18K gold is 18 parts gold to a total of 24 parts, with 14K, 10K and 9K gold following the same method of measurement. 


18K gold-plated

In our 18k gold-plated jewellery collections, the enhanced thickness of the precious metal, 18k gold, makes our jewelry more hypoallergenic, ensuring comfortable wear. This durability factor reduces the likelihood of fading, tarnishing, or wearing off, promising enduring beauty that lasts.



Unlike gold-plated jewellery, vermeil is a thick layer of 18K gold that is placed on top of sterling silver. A combination of high-quality precious metals, vermeil gives you greater value without the added cost. At Helene, at least 2.5 microns of pure 18k gold is plated on top of sterling silver to create affordable high quality jewellery. Gold vermeil is five times thicker than normal gold plating. This thickness of previous metal makes our jewellery more hypoallergenic, durable and less likely to fade, tarnish or wear off.
