How To Choose Your Gemstone:

RIO carries the following gemstones: Ruby, emerald, aquamarine, amethyst, opal, citrine, sapphire, onyx, topaz, tourmaline, peridot and morganite. Take note of the below when choosing a gemstone:


Hue – The hue refers to the gemstone’s primary colour. Look for a hue that is strongest in its primary colour, with lesser hues mixed in from other colours.

Tone – Tone refers to the gemstone’s depth of colour. A gemstone’s tone can range in light to dark shades.

Saturation – Saturation refers to the vibrancy of the gemstone’s colour. Look for a pure, vivid colouration that is free of grey or brown shades.

Cut and Clarity:

The ideal cut should best showcase symmetry, colour, proportion and contain the fewest inclusions. However, it should be noted that flawless gemstones are extremely rare as almost all gemstones contain inclusions. For example, emeralds and rubies have higher inclusion rates naturally amongst gemstones.



Pearls and alexandrites make up the two birthstones for people born in June. With its classic beauty, pearls are a sign of youth, modesty, success and purity. The extremely rare alexandrite is known as an ‘emerald by day, ruby by night’ for its unique colour-changing properties depending on the lighting.



Known as the king of gemstones and a symbol of nobility, the deep red colours of the ruby signify passionate love, commitment, success and wisdom.



People born in October have a rainbow of colours to choose from in the opal and tourmaline. Opals are known for their one-of-a-kind flashes of colour, while tourmalines mostly range in pink, green, blue and red. These October gemstones are said to inspire creativity, hope, balance and confidence.



At once regal and serene, the royal blue colours of the sapphire signify wisdom, loyalty, nobility and commitment.
