Find the Aquamarine Piece That Fits Your Style
Aquamarine is a member of the beryl group, just like emerald. However, unlike its fellow gemstone, it has greater transparency and clarity, with high-quality stones being completely see-through with no cloudiness. There are some specimens with a slight icy blue hue, while others tend to have a bluish green color.
Aquamarine has a distinct appearance compared to other blue gemstones.
Aquamarine is used extensively in jewellery as it is quite durable for regular wear. This gemstone’s hardness rate falls between 7.5 and 8 on the Mohs scale, which means it can be used for rings, earrings, necklaces, pendants, and bracelets.
Today, most aquamarine gems in jewellery are mined in Brazil, Madagascar, and Nigeria. The higher the clarity of an aquamarine stone and the stronger its color, the higher its value.

Find the Green Tourmaline Piece That Suits You
Green tourmaline is hard enough for daily wear and affordable at sizes where other green stones are not, so it suits generous designs that would be unrealistic in emerald or tsavorite.

Our Ring Collection
Aquamarine Rings
Aquamarine rings have a fresh and light appearance and do not carry the weight that some other dark stones have.
While some customers choose a vintage style featuring engraving, a milgrain edge or even filigree, others opt for a simple, elegant design, one which puts the emphasis on the stone. Both designs will work well depending on the type of aquamarine used and its color.
Our Rings Collection
Green Tourmaline Rings
Green tourmaline is hard enough for a ring worn daily and cheap enough to be used generously, which is an unusual combination in a green stone. Most of what we make is a solitaire in a size that would be unaffordable in emerald or tsavorite.
Yellow gold warms the stone and suits the deeper forest greens. White metal keeps a lighter mint green crisp.

Our Earrings Collection
Green Tourmaline Earrings
Matching green tourmaline is more work than it looks, because colour depends on how each stone was oriented at the cutting wheel. We match for face-up colour rather than for grade on paper.
Our Pendants Collection
Green Tourmaline Pendants
A pendant is where a large green tourmaline makes sense — the size that would be heavy in a ring hangs comfortably, and the colour sits well against most skin tones.

The Detail
The Facts Behind Aquamarine's Timeless Beauty
What every property actually means for the jewellery you wear every day
| Property | Value | What It Means for You |
|---|---|---|
|
Hardness (Mohs) |
7.5–8 |
Very durable and suitable for everyday wear in rings, bracelets, and pendants |
|
Transparency |
Transparent |
Light passes through the stone completely from one side to the other, which is what creates that luminous, glowing quality aquamarine is known for. The cleaner and more transparent the stone, the more light it holds and the more alive it looks when worn |
|
Luster |
Vitreous |
The surface reflects light the way polished glass does, bright, clear, and sharp. This is what gives aquamarine that clean, refreshing appearance that catches the eye even in low light |
The detail
The Facts Behind Green Tourmaline
What each property actually means for a piece you intend to wear
| Property | Value | What it means for you |
|---|---|---|
| Hardness (Mohs) | 7 – 7.5 | Suitable for a ring worn daily. Harder than opal, quartz or tanzanite, and without the fractures that make emerald a specialist’s stone. |
| Transparency | Transparent to translucent | Cleaner stones carry more brightness; slightly included material is common in green tourmaline and is often what makes a larger stone affordable. |
| Pleochroism | Noticeable | The stone is usually darker down the length of the crystal than across it, which is why cutters orient green tourmaline carefully. A well-cut stone stays bright rather than going black at the centre. |
| Typical treatment | Sometimes heated | Heating is used to lighten over-dark material and is permanent. Much green tourmaline is untreated; we will tell you which you are looking at. |
| Available size | Large sizes realistic | Unlike tsavorite, green tourmaline reaches generous sizes without the price becoming unreasonable, which makes it a good choice for a statement piece. |
Colour
Colour of Aquamarine Stones
There are various shades of blue for aquamarines. The colour ranges from light icy blue through to deep blue-green. We can show you the range in colour and assist you in selecting the right stone for your design.
Light Aquamarine Stone
Lighter aquamarine stones have a subtle icy hue and will suit everyday jewellery designs.
Medium Aquamarine Stone
This colour is a popular choice for aquamarines. Gemstones in this category will give off a bright, vivid, and bold blue colour.
Dark Aquamarine Stone
The darker aquamarine stones offer a rich blue-green hue with high visibility and are often used in statement pieces.
Colour
The Colour Range of Green Tourmaline
Green tourmaline runs from a light yellowish green through to a deep forest green, with the chrome-bearing material at the vivid end. Because the stone is pleochroic, cut matters as much as colour grade — ask to see a stone under both daylight and electric light.
Forest Green
The commercial centre: a deeper, cooler green that holds its colour well under electric light.
Chrome Green
Coloured by chromium rather than iron, this is the vivid, emerald-like material. Scarcer and priced well above ordinary green tourmaline.
October Birthstone
Green Tourmaline, an October Birthstone
Tourmaline is October’s second birthstone, and the more practical of the two: opal is soft and sensitive to temperature, while tourmaline is hard enough for a ring worn every day.
Green tourmaline is the most plentiful colour the species produces, which makes it one of the few genuinely hard green stones available in larger sizes at a sensible price. It is also the usual choice for anyone who wants green without emerald’s fractures or tsavorite’s size limits.

Questions We Are Asked Most Often
What is green tourmaline?
The green variety of elbaite tourmaline, sometimes sold under the older trade name verdelite. Tourmaline occurs in more colours than any other gem species, and green is the most plentiful of them.
Is green tourmaline suitable for an engagement ring?
Yes. At Mohs 7 to 7.5 it handles daily wear well, and it has no cleavage plane to chip along. It is a more practical green than emerald and reaches larger sizes than tsavorite.
What is chrome tourmaline?
Green tourmaline coloured by chromium or vanadium rather than iron. It is noticeably more vivid, closer to fine emerald in colour, and costs considerably more than ordinary green tourmaline.
Why do some green tourmalines look dark?
Tourmaline is pleochroic and usually darker along the length of the crystal. A stone cut to the wrong orientation reads dark or black at the centre. It is a cutting decision rather than a flaw in the material, and it is one of the first things we check.
Is green tourmaline treated?
Some is heated to lighten over-dark colour, which is permanent and standard. A good deal of it is untreated. We tell you what a stone has had done to it before you commit.

Questions We Are Asked Most Often
What is Aquamarine?
Aquamarine is actually a member of the beryl family which includes emerald and morganite. The blue-green color of aquamarine is due to small amounts of iron within its molecular structure, while the natural transparency of the stone creates exceptional sparkle and shine in the finished piece of jewelry. It’s a reliable gemstone that retains its beauty in every light.
Which setting protects an aquamarine ring best for daily wear?
Bezel setting will protect your aquamarine by encircling the edges of the stone from potential damage due to daily usage. A halo setting surrounds the center stone with additional diamonds or gemstones and provides added protection to the edges of the stone. Claw setting exposes more of the edges of the stone, however also provides the best visibility of its color.
How do I start a custom aquamarine piece?
Send us an enquiry with what you have in mind: the piece type, the occasion, any images or references, and a rough budget. We will arrange a consultation in our Burnside studio or work through the details with you remotely. Stone selection, setting design, and metal choice are all decisions we make together, from the first conversation to the finished piece.
How do I check pricing and availability?
Contact us directly with the piece you are interested in or a description of what you are after. We will confirm what is currently available, provide pricing and outline lead times, then walk you through the next steps, whether that is a visit to our Adelaide studio or delivery within Australia.
