Not a Love Letter to Emerald

When I first started out in jewellery, I used to make lamp-worked beads and I sold my jewellery in various shops and galleries. One of the shops always said to me, ‘no green please. People don’t buy green jewellery.’ Well, times have changed and green is definitely having a renaissance. Of course, if you talk about green stones, the first one that comes to mind has to be emerald. I have to say that I am not a massive fan of the big E; why not? Well, it’s a combination of its price and properties. Emerald is generally a very included kind of stone. Most emeralds have inclusions; gas bubbles, liquid inclusions, minerals and fractures. And oh my goodness; the fractures. It’s not known whether emerald is a generally fractured stone, or whether it’s the extreme processes required to get it out of the ground. Either way, what this means is that emerald tends to be fracture filled. Something like 96% of all emerald on the market is fracture-filled. This means that clean emerald is very rare and very expensive, and that cheaper emerald is generally highly included, almost certainly fracture filled and the lustre just isn’t great. Emerald is also a rather brittle stone, and of course, as we all know, fractures will tend to make a stone more brittle; if you have a fracture filled stone, then it will appear much less fractured than it actually is, and therefore – dangerously – appear more stable than it actually is. It’s not a great choice for a ring stone. In recent years, emerald finds in Afghanistan have turned up high quality, intense green and relatively clean stones, but obviously there are issues involved with mining in that part of the world.

If you had to give me a choice, my top pick for a green stone would be tsavorite garnet. It comes in a stunning intense green, it has fantastic dispersion (it’s very sparkly!) it’s durable, free from inclusions and is not generally treated. It isn’t cheap, but small stones are reasonably priced and they have a beauty and brilliance that you just don’t get with emerald. Below is Anderson Beattie’s Opal & Tsavorite Garnet Ring; the opal really brings out the chrome green shade of the tsavorite.

Chrome diopside is another intense green option. It really isn’t well known and that’s a shame as colour-wise it packs a punch. It retains its intensity of colour even in small sizes – conversely this means that the colour can get very closed in large sizes, and really you don’t tend to see this stone above around 8mm.

Tourmaline: ah my favourite stone of all time. Green tourmaline runs the spectrum from aqua blue through to yellow ‘beer bottle’ green, with all shades of green-blue, blue-green, intense chrome green and light green along the way. Additionally, because tourmaline is so pleochroic, you will often get several shades of green in the same stone – the ring below from Disa Allsop is a really clear example of this where you can see the bright green and gold green colours dancing across the stone. I also love the way that Lola Brooks uses this spectrum of greens in her jewellery. Mimi Favre’s triple claw setting ring also demonstrates the colour range of tourmaline and Monika Krol’s asymmetrical green tourmaline pendant highlights the beauty of this stone set in gold.

Peridot runs apple green through to yellow-green. It’s reasonably priced and so it’s possible to have it in much larger sizes. For me its at its best en cabochon in a nice strong setting. It’s not hard to find clean stones but larger stones can be prone to black inclusions. However, if you can find them, peridot can have very characteristic ‘lily pad’ inclusions, which I think are rather beautiful. Below is Barbara Tipple’s Lioness Peridot Torque, whose powerful linesperfectly showcases the beauty of this stone.

And this ring from Tayma Fine Jewellery – a large, highly included peridot which looks knockout in this strong and simple setting.

Timeless, enduring, serene…but maybe, a little bit boring?

I am referring, of course, to Pantone’s Colour of the Year, Classic Blue. I don’t know, I find I am often a bit bemused by their picks. Along with everyone else, last year’s Living Coral seemed bizarre. This year, they are clearly playing it safe, but is it too safe? What do they say?

“We are living in a time that requires trust and faith. It is this kind of constancy and confidence that is expressed by Pantone 19-4052 Classic Blue, a solid and dependable blue hue we can always rely on,” says executive director of the Pantone Color Institute, Leatrice Eiseman.

Ok, yes. Solid and dependable; words to make the blood start pounding through your veins? Not really. He goes on to say,

“A boundless blue evocative of the vast and infinite evening sky”

Ok, that’s better, and I can see that. It is a very definite shade of blue; a strong colour, but not a loud one. ‘Full fat’ says Michelle Ogundehin and it’s a good description. Blue skies thinking, celestial skies, deep blue seas, all lovely connotations. But also sadness and depression; having the blues. It’s an interesting choice too, when other colour forecasters, for example WSGN, have opted for green shades, in keeping with the current focus on sustainability and, well, green issues.

I do think there’s a difference when it comes to colours between clothing and jewellery. I can’t see myself wearing this blue in clothing form. It’s at once too loud and not distinctive enough. It’s the colour of store uniforms and cheap balldresses from Moss Bros. However, when it comes to gems, it’s a different matter, because the two biggest stars are sapphire and lapis lazuli. At opposite ends of the value spectrum, still there are affordable sapphire cabochons and lapis is making inroads into fine jewellery. Sapphire is my birthstone and yes, one of my favourite gems. But lapis is something else; still inexpensive enough that it can be used in large, experimental pieces, it frequently appears in very contemporary looks, and yet it has a pedigree that stretches back centuries. When set in gold, it evokes Renaissance paintings when, crushed, it provided the blue pigment for the Madonna’s dress. In silver it is clean and sharp.

Sapphire is more expensive and rare, and therefore the jewellery tends towards the more classic and traditional. Big, set-piece engagement rings surrounded by diamonds (like my own!). However, sapphire does also lend itself to a clean, contemporary look, princess cuts set in white metal or larger cabochons in plain settings.

Other stones that could fall under the Classic Blue hat are London Blue topaz and iolite, although the former shades a bit green and the latter a bit purple. In terms of gems, I carry a range of all these stones. To view my Classic Blue collection, click here.

When is Clarity not Clarity?

Amethyst Tavernier Cut Gemstone, 22x19x4mm, 17.11 carats, $170

Clarity’s a simply enough concept, right? A stone is clean or not and it’s clarity is described in neat categories. Well, no, not really. Diamonds are one thing, with the scale running from Flawless to Included, but the similarly categorised scale for coloured gems is a bit more complicated. And if you think about it for one second, this makes perfect sense. Because with diamonds, clarity is a huge value-factor. It has to be accurate, reliable and valid. It has to be able to be taught so that everyone grading the stones is doing roughly the same thing. But coloured stones are different, and one of the biggest ways they differ is in terms of their clarity types. This is a system of classification developed by the GIA to describe the way in which some stones, above and beyond the level of clarity of an individual stone, are basically more included than others. It divides stones into 3 types, and each clarity grade means something different for each type. It goes like this:

Type I Stones:

Joopy Gems Aquamarine (Clean) Rose Cut Freeform, 2.83 carats, 12.1x9.7x3.5mm, $55.95 — Joopy Gems Aquamarine (Clean) Rose Cut Freeform, 2.83 carats, 12.1×9.7×3.5mm, $55.95

Stones that are usually eye-clean. For example, aquamarine, chrysoberyl, smoky quartz and blue zircon (there are others). These are stones that it’s not hard to find in clean quality, and for these, a VS stone means an eye-clean stone with inclusions that can be seen under 10x magnification.

Type II Stones:

These are stones that are usually included. For example, corundum, garnet, iolite, peridot, tourmaline, amethyst. These are stones that will usually have some degree of inclusion, and for these, and a VS stone will likely have noticeable inclusions under 10x magnification and these may well be eye-visible.

Type III Stones:

Pink Tourmaline Rose Cut 3mm Round Cabochon

These stones are almost always included, and yes emerald, I’m talking about you. Because it’s hard to find clean crystals the standards for a VS stone are pretty low and so a VS type III stone will have obvious inclusions at 10x magnification which will be likely eye-visible. Such stones are, yes, emerald and the red and pink tourmalines. As well as red beryl, not that we are likely to come across a lot of that!

All of this ought to be obvious, but I am aware that when we talk about stones, we get hung up on things like clarity and grades, whilst forgetting that sometimes clean stones are just not realistic. Stones are natural, they come out of the ground. The marks and trauma within tell the story of their birth. All of this should be celebrated and there’s a place for every kind of stone, however included. As with everything, information and disclosure is the key.

Below you can see how beautiful included stones can be. On the left is a ring made from a tourmaline bought by a customer. This was made by Custom Jewelry Co in Australia. This is an included tourmaline but it’s just beautiful, like a map of the world.

It’s only relatively recently that black diamonds have become prized as gemstones in their own right. Traditionally either thrown away or used solely for industrial purposes, it’s really only in the past thirty or so years that they have come into their own. Now called ‘fancy blacks’, they began their popularity streak when designers started using them to contrast with colourless stones in pave settings and have got bigger and better ever since, in fact you might say they finally ‘arrived’ when Mr Big gave Carrie a 5 carat black diamond ring at the end of Sex and the City 2! Since then, there have been more high-profile black diamond engagement rings and of course, prices have risen in line with their popularity. They are unique stones, having the adamantine brilliance you’d expect from a diamond, despite the fact that they are black and opaque. They glitter, like mirrors, with a silvery lustre. Still, there are relatively few famous black diamonds, one of which is the Black Orlov which comes laden with the usual kind of myths and legends of curse and disaster.

But what is a black diamond? Conversations with customers over the years have told me that this gemstone is not well-understood. Natural black diamond is, in fact, simply diamond that is so included with mineral inclusions, such as haematite, pyrite and graphite that it appears black. It is also often criss-crossed with minute cleavages and fractures that are either stained black or have become black due to graphitisation (the formation of graphite due to a process too arcane for me to wrap my feeble head around). And in fact, a great deal of black diamond on the market is irradiated, so that the inclusions turn black. I always state the black diamond I sell as irradiated, as I am generally not sure and better to be safe than sorry…

The upshot of this is that black diamond is rather brittle, and it is this that causes confusion. Yes, diamond is hard; very hard. But hardness is not the same as toughness. Glass is hard but will shatter if you drop it; putty is soft but you can drop it and it will remain in one piece. Black diamond, filled with inclusions and riven with tiny fractures is pretty brittle. Don’t drop it, don’t – as a friend of mine did – slam it in a car door and do set it with care. You can also expect it to be rather prone to pitting, certainly on the base and around the girdle and often on the facets edges and corners. But if you can live with all that, you’ve got a gemstone like none other. Below, I love the contrast of the black and white diamonds, accentuated by the use of silver and oxidised metals in this Coco & Chia stacking ring set.

You can clearly see, top, the included nature of black diamonds in this beautiful rose cut black diamond ring from Lex Luxe – you can actually identify the blackened, frondlike clouds of inclusions. Another option from this jeweller is this black and white diamond cuff bracelet, with the contrasting colours offset by oxidised metal. And, right, just because it’s black, doesn’t have to go in white metal; this black diamond cluster ring (bottom) by Ferkos Fine Jewelry is set in 14k gold.

At Joopy Gems we carry rose cut black diamonds in a range from 3mm-5mm. These are sized pretty precisely as small differences make a disproportionate difference in terms of price when the carat price is high. The 3mm and 4mm stones are of slightly higher quality than the other sizes but you can expect the odd pit and fracture as is normal with this stone. To browse the entire range, click here.

Blowing my own trumpet

Well, it’s a bit of blowing my own trumpet, but it’s in the name of giving you, my brilliant customers, some extra reassurance. Before the summer, I passed my GIA Gem Identification module, the last part of my Coloured Stones qualification. This was a completely practical, hands-on module, which involved the identification of 500 stones. These came in boxes of 20, posted from the GIA. I had to fill out a worksheet, scan and send back to my tutor in the US and pass each worksheet before moving on to the next one. As you might imagine, this took a little while. One year, to be precise, of late nights, early mornings, scrambled brains and inspiration. I learned so much over this time, not just how to separate different stones, but how to tell a synthetic from a natural, and even what kind of synthetic. This has been especially helpful in giving me confidence to offer precious stones; rubies, sapphires and emeralds. Finally I had to sit an exam, with a proctor approved by the GIA; identify 20 stones. You’ve got 6 hours, and by the way, you’ve got to get them all right to pass. Yes, that’s right; this exam has a 100% passing grade. And I did it! I passed! First time! I am still reeling with joy! So I now have my Coloured Stones qualification and I am starting the last few diamonds modules, after which I will be a fully fledged Graduate Gemologist. Loving my studies!
