Heliodor Gemstone

A gift from the sun that can be set into jewellery.

A clear and flawless Heliodor will exude brilliance and sparkle like a Canary Diamond. Because of its rarity, Heliodor is a gemstone highly appreciated by collectors and enthusiasts alike.
Precious Beryl was another name given to this golden yellow variety of Beryl in order to distinguish these beautiful gems from Yellow Topaz and Citrine. Golden Beryl has more yellowish hues, whilst Heliodor has a greener tinge.

Heliodor is from the Greek words for sun, “helios”, and gift, “doron”, thus Heliodor can be translated as “gift of the sun”. As with all members of the Beryl family, the gem receives its colour from impurities; in Heliodor’s case it is from the presence of iron.

So as to best display the gem’s stunning colours, lapidarists will normally step cut or emerald cut the gem. Heliodor is normally transparent, but occasionally can be found translucent. When this is the case, the gem is often cabochon cut and sometimes chatoyancy or asterism can be visible.

As with other members of the Beryl family, Heliodor has a good hardness, measuring 7.5-8 on the Mohs scale, making it ideal to set into jewellery. We include it in a host of different designs, including charms, 9k Gold and Silver.

It is said that Heliodor can increase self-confidence and self-belief. It’s also claimed that meditating with the stone can awaken one’s ‘inner flame’, thus enabling one to find their self worth and their place in the grand scheme of things. It is also associated with the astrological sign of Leo.

When I am sourcing Heliodor I am always looking for a good balance of colour and brilliance. In my mind I have an image of a natural yellow Diamond and I am always scoring pieces of Heliodor against this image. If the hue is not strong and the tone not sufficiently dark, then I never buy the parcel. Likewise if the gem’s brilliance is not dancing and twinkling like mad I walk away. Over the years, I have probably turned down 95% of the Heliodor I have been offered. For me, the gemstone has to possess a magic that puts it on a level footing with its older sister Emerald and if I can’t then liken the piece before me to Yellow Diamonds then I simply won’t invest in it.

Golden Beryl, Yellow Beryl, Imperial Beryl, Precious Beryl or Heliodor, whichever you prefer to call it, is a gemstone which once you have purchased you will never look back. The good news is that as it’s not as well known as its twin sister Aquamarine, its prices are a fraction of what you would expect to pay for such a phenomenal gem. The gem is mentioned numerous times throughout the Bible.

Heliodor is mined in Madagascar, Brazil and Nigeria. The gem is also mined in the Ukraine and some pieces uncovered in this location are of the finest quality ever discovered.
