Ethical birthstones, gemstones and the meaning behind them

A Guide to Gemstones: Colours, Properties and Meanings

ethical yellow sapphire

The rising popularity of coloured Gemstones has been apparent for some time now. 

Not only are people fascinated by their properties and meaning, but they are becoming increasingly sought-after in the jewellery industry, with many choosing to incorporate coloured stones in engagement rings and dress jewellery. This interest can be attributed to the ebbs and flows of fashion trends, much like silver and gold tend to switch in popularity. 

We have written a blog previously about Ethical Gemstones And How To Buy Them, but wanted to delve a little deeper to explore the properties and meanings of their associated months.

Before we begin, here are a few things you should know about ethical gemstones and where they are sourced.

Are coloured gemstones ethical?

There is quite a bit of controversy surrounding coloured gemstones as they can't always be traced back to their origin. This is partly because unlike the diamond industry, gemstones are not monitored as closely and tend to come from small-scale mines.

To understand if a gemstone is ethical, you must be able to trace each and every point along the production process. Without this, we would have no idea of where it was mined or cut.

If you are looking to purchase ethical gemstones, you need to look out for a supply chain that can be fully verified or traced, evidence of the source and the process and whether the dealer or brand is forthcoming in offering details of sourcing and production.

The importance of an ethical supply chain

Unlike diamonds and precious metals, gemstones have quite a complex supply chain. This is because they tend to be mined, cut, and sold in different countries. 

In saying that, there are more and more reputable suppliers with transparent supply chains.

In order to understand how to buy ethical gemstones and identify these reputable suppliers, it is essential that you get to grips with the supply chain structure and learn what to look out for. 

So long as these stages are all audited along the way and there are traceable proof points, you can be confident that your gemstone is ethical. Here is the supply chain in its simplest form:

Mine - rough stones

Cutting - the practice of shaping and polishing the stone

Market - gemstone buyers/dealers

Jeweller - someone like me, who sources gemstone’s to make jewellery

Consumer - you, the wearer

Meanings and Properties

There are 12 gemstones, or birthstones, that we associate with the months of the year. The popularity of birthstones dates back to ancient times when civilizations believed that gemstones had powers and healing properties.

Birthstones can be the standout feature of a piece of jewellery and have great personal significance. So if you’re looking to treat yourself or someone special, or simply want to understand the gemstone meanings, let’s take a look at this gemstone list to explore their properties. 

January - Garnet

Garnets are generally recognised for their rich red colour however, they come in a variety of different colours. 

Meaning: As a reflection of it’s red colour, the stone is associated with love and protection.
