Stone shapes

I wrote recently a bit about the difference between types of stones, specifically faceted stones, and cabochon cuts, but that's not the only thing to consider in the stones you choose.

I'm making more and more sets of stacking rings these days, and it's so lovely to use a variety of shapes and sizes in the stack.

I'm always adding more options to my stone collection, so won't list here all of the different shapes and sizes I can offer in each stone choice - for the most up to date information, just get in touch and I'll be able to let you know the options. But here are the key shapes...

Round

These are the rose cut, faceted and cabochon stones that I use most often;

The size of cabochon I most often use within ring stacks are 6mm and 5mm. 

cz faceted round

The most popular size of faceted stones are 5mm, such as in this cz ring above.

Oval 

Again ovals are available in cabochon, rose cut and faceted stones, and come in a variety of sizes. The most common, that fits nicely into a ring stack is a 7x5mm oval.

Square

The square sizes I most commonly use are 4mm and 5mm. These can be a little tricky to get hold of in a lot of gemstones but are readily available for rubies, sapphires, cz, and a few others.

The stack in the photo at the very top of this page shows a lovely turquoise cabochon.

A slight alternative to the square is a cushion cut which is a square cut stone with slightly rounded corners.

Triangle (Trillion)

The trillion stone has a few variations. It is a triangular cut, but can have straight or slightly curved edges, and often has soft points. 

Peridot trillion (a curvy number!)

This post is already a little picture heavy, but I hope it gives you an idea of the most popular stone shapes, that are readily available in a number of gemstones. I'll put together another post shortly with a few of the other options... octogon, teardrops and freeform. 

The difference between cabochon and faceted stones

I've been getting loads of requests for custom birthstone stacking rings recently, and a question that always comes up in conversations about stone choice, is about the difference between cabochon and faceted stones. And what on earth they are anyway.

So here goes, my attempt to clear up any confusion.

What is a cabcohon stone?

A cabochon is cut with a flat back and a domed top....

Sapphire stacking ring

Like this sapphire stone in the ring above. It has a smooth dome on top, and a flat back. It is set in a bezel setting.

What are faceted stones?

The other kind of stone I often use is a faceted gem.

These stones usually have a pointed back, with facets or cuts taken from the stone which helps to bounce the light around. Faceting a stone is a key way to add value to a transparent stone, as it gives a higher luster and a better play of colour in the stone.

The Cubic Zirconia above is a manmade faceted stone - I've shown this picture as hopefully you can get an idea of what the stones are like, but for stacking rings I tend to use more enclosed settings like the one below...

....so you only see the sparkly top of the stone.


Some stones are much more commonly found in one sort or the other. For example, turquoise (the birthstone for December) and opal (the birthstone for October) are pretty much always cabochon stones.

What the heck are rose cut stones then?

So, now for my fave stone of the moment - the rose cut stone. This is a kind of crossover. It's a cabochon stone (so it has a flat back and a dome) but it's also faceted...I know confusing! Here's a diagram..

Rose cut stones went out of fashion for a while, because they don't really add much brilliance or light to the stone. But I've gone completely crazy for them - I like that they're a little unusual and quirky, and I love how they bounce the light.

So there you go - a very quick guided tour of some of the types of stones I use!

I'll also put together a post on the different shapes I can offer. Sadly my shop is a little out of date - so many of the things I make still haven't made it to a listing, so if there's something you'd like in particular, just email me hello@beckypearcedesigns.co.uk to discuss. I could have the perfect stone sitting in my stash right now.
