Fenton Aquamarines

We source this dreamy stone from Sri Lanka, Thailand, Zambia and Mozambique. With a Mohs hardness scale of 7.5-8, they are suitable for daily wear but should be handled with care. Resembling the colour of the sea in light blue and slight green undertones, each Aquamarine is unique in its appearance and no two will ever be the same.

Water of the sea

Aquamarines got their name from Latin words Aqua meaning ‘Water’ and Marina meaning ‘Of the sea’. Sparkling like a crystal clear ocean, the Aquamarine was believed to be the treasure of mermaids. Used by sailors as a talisman for all that it symbolises, the colour Aquamarine is "alive"- in the evening, or in candlelight it shines brighter. It’s also been a favourite since Medieval times, when newly-weds exchanged Aquamarine rings as an amulet for a happy family life. Want to know more about this majestic gemstone?

The Four C's

Cut

Unlike diamonds, coloured gemstones are cut by hand. This means they’ll never be perfectly symmetrical, but each stone cutter, or lapidary, will maximise a rough crystal to achieve its highest potential in size, colour, inclusion distribution and sparkle.

Colour

Colour should be evenly distributed across the stone. We look for excellent qualities of:
• Hue (the basic colour we see)
• Saturation (the intensity of the hue)
• Tone (the gemstones relative lightness or darkness)

Aquamarines have a light blue, glassy appearance which allows light to pass through easily and sparkle.

Clarity

As creations of nature, all gemstones will have clarity characteristics such as tiny lines of growth, crystals or needles, called inclusions - which may be visible to the naked eye.

Carat

Weight is typically measured in metric carats, where five carats equal one gram. However, we focus on surface area instead, as gemstones can vary hugely in their proportions and depth. Providing the size using millimetres gives a more consistent depiction of the surface area of your gemstone, and how it will look in reality.

We have 5 sizes:
Original - 8x6mm or 6mm round
Big - 9x7mm or 7mm round
Bigger - 10x8mm or 8mm round
Biggest - 11x9mm or 9mm round
Grand - 12x10mm or 10mm round

FAQs

What quality are your Aquamarines?

We do not label our gemstones with particular quality gradings, as these gradings are not standardised across the industry and mean different things to different professionals. Each of our gemstones follow slightly different quality parameters, as each gemstone is beautifully and inherently different to the next. When grading gemstones on lab reports, gemmologists use the colour of the gemstone and the clarity.

Are Fenton Aquamarines treated?

Fenton only works with natural coloured gemstones that are treated in a way which follows the highest jewellery and gemstone industry standards. Our Aquamarines will typically be heat treated, which improves the colour intensity of a gemstone as well as some inclusions. This does not include other chemicals and will not change in appearance over time.

How can two of the same gemstone look different?

Gemstone crystals are all unique in the way they grow. For example, two different Aquamarines share the same chemical identity, however depending on where they grow, they may have different concentrations of chemicals which make them blue. These different concentrations will result in one stone being lighter, the other darker, and a completely unique distribution on inclusions inside each.

Why are Fenton Aquamarines cheaper than other brands?

Our philosophy is to cut middlemen, but never corners. By stripping out the antiquated supply chains of the industry we save you 2-5x the markup traditional jewellers add, through unnecessary middlemen. Saving you the £1000s added every time a stone changes hands.
