You don't need to know how to buy a loose gemstone.

You don't need to know how to buy a loose gemstone.


Perhaps you know the colour you love. You've saved photographs. You know the shape you're drawn to.But when it comes to actually buying a loose gemstone, suddenly there are a lot more questions.

How do I know it's a good stone?

What about quality, treatments and inclusions?

How do I know I'm paying the right price?

You don't need to become a gemstone expert to buy an extraordinary gemstone.

You can have one working for you.

Your wish list is coming to Bangkok with me.

METAL & STONE | BANGKOK 2027

Your wish list is coming to Bangkok with me.


From 23–27 February 2007, I’ll be in Bangkok attending the Bangkok Gems & Jewelry Fair and sourcing gemstones for a limited number of Metal & Stone clients across Australia.

But I won’t just be looking for beautiful gemstones. I’ll be looking for yours.

Before I leave, we’ll create a personal sourcing brief based on the gemstone you’re dreaming of — your preferred colour, shape, size, purpose and budget.

I’ll take that brief with me to Bangkok and use my experience and expertise as a qualified gemmologist to search for stones that I believe are worthy of your consideration.

When I find something special, you won’t have to wait until I return to see it. Through videos and conversations, you’ll be part of the experience from Australia.

Your ideas. Your budget. Your gemstone wish list.

BE PART OF THE DISCOVERY

Come gem shopping with me — from Australia.

I find it. I examine it. You see it. We talk. You decide.

START WITH WHAT YOU LOVE

Don't know exactly what you're looking for?

You don’t need to arrive with the perfect gemstone already mapped out.

Perhaps you know you love a particular colour. Maybe you’ve saved a few images, have a shape you’re drawn to, or simply know how you want the finished piece to feel.

That’s more than enough to begin.

During your complimentary consultation, I’ll help you explore those ideas and turn what you love into a clear gemstone brief — considering colour, shape, size, purpose and budget.

You bring the inspiration. I’ll bring the gemstone expertise. Together, we’ll work out what I should be looking for.

Beauty catches the eye. Expertise looks deeper.

MEET SONYA LORENZ, YOUR GEMMOLOGIST

Beauty catches the eye. Expertise looks deeper.


When I’m looking at a gemstone, of course I notice the things you notice first — the colour, the sparkle, the way it catches the light and that instant feeling of “Oh, I love that.”

But my eye naturally goes further.

As a qualified gemmologist and jeweller, I’m also looking at the things that may not be obvious at first glance. I’m considering the gemstone as a whole, asking the questions that come from my training and experience, and thinking about whether this is a stone I would genuinely feel confident recommending to you.

I completed my gemmological training with the Gemmological Association of Australia and am proud to be a Fellow of the GAA. I’ve also completed further training in Diamonds and Coloured Gemstones with the Gemological Institute of America (GIA).

But qualifications are only part of what I bring to your search.

Over the years, I’ve developed my eye as a jeweller, built relationships with gemstone suppliers and created a network I can call upon when I’m searching for something special.

And perhaps most importantly, I’ll know who I’m searching for.

Before I begin, we’ll have talked. I’ll know what you love, what you don’t, what this gemstone means to you and what you hope it will eventually become.

So when I’m standing in Bangkok surrounded by thousands of gemstones, I’m not simply looking for a beautiful stone.

I’m looking for the one that feels right for you.

Stories From My Clients

Gemstones Found. Stories Created.

I have the ring of my dreams! Thanks to Sonya with her vast knowledge and passion for gemstones made it an easy and pleasurable experience. The gem I was looking for was a pink diamond. We discussed my budget. I enjoyed the communication we were having while Sonya was sourcing the gem. I felt very confident Sonya would find it. I appreciated Sonya’s personalised approach and professionalism Within a very timely manner Sonya excitedly said she found it. “It is perfect”
Karen M.

I want to thank you Sonya for the lovely personal service when selecting the perfect gem for my ring I had made in memory of my late parents. It was a very special and personal piece of jewellery and your kindness and caring manner paired with your knowledge was very appreciated. You were also very quick to find the perfect gem and went above and beyond for me so that I could have a beautiful memory. Much appreciated and I wouldn't go to anyone else.

Sonya suggested trilliant diamonds to sit alongside a gem I already owned. Your suggestion was perfect. The quality of the gemstones and the sparkle they have is perfect. I would highly recommend using Sonya from Metal & Stone Jewellers if you need a gem sourced that perfectly meets your requirements

Choose Your Gemstone With Confidence

A personal search, backed by professional expertise

Your initial gem sourcing consultation with me is completely complimentary.

It’s our opportunity to talk about what you’re looking for, explore the colours, shapes and gemstones you’re drawn to, discuss your budget, and begin creating a clear picture of the stone you’d love me to find.

If you decide you’d like me to take the next step and personally source on your behalf, you can secure one of the limited places on my buying list with a:

$300 Professional Gem Sourcing Fee

This fee is for my time, expertise and commitment to your individual search.

I’ll take everything we’ve discussed and create your personal gemstone brief. Then, rather than simply showing you what happens to be available, I’ll actively search for gemstones that meet your requirements—assessing potential stones through the eyes of a qualified gemmologist and jeweller.

Your sourcing fee includes

✓ A personalised gemstone sourcing brief
✓ My professional gemmological expertise
✓ A dedicated search based on your requirements and budget
✓ Assessment of potential gemstones
✓ Videos and personal communication as suitable stones are found
✓ Guidance to help you confidently choose your gemstone
✓ Access to my established supplier network
✓ A continued search after Bangkok if we don't find the right stone during the trip

The gemstone itself is separate

The $300 sourcing fee is a professional service fee and is separate from the purchase price of your gemstone. It is not credited towards the cost of the stone.

Your gemstone budget will be established with you before I begin sourcing, so I know exactly what parameters I’m working within.

And importantly, my job isn’t simply to find you a gemstone.

It’s to use my expertise, experience and network to help you find a gemstone that I’m confident putting in front of you—and that you’re genuinely excited to call your own.

Start with a complimentary consultation.

It starts with the gemstone

Bespoke Jewellery by Metal & Stone Jewellers

It starts with the gemstone


A beautiful piece of jewellery begins with a gemstone that makes you feel something.

The colour. The shape. The way it catches the light. That moment when you see it and simply know.

By personally sourcing your gemstone, we begin with the stone itself — then let its individual beauty inspire everything that comes next.

First, we find the one.

Then we create around it

Bespoke Jewellery Designed in Australia

Then we create around it


Once we’ve found your gemstone, its story can continue at Metal & Stone.

Together, we can design a bespoke piece that celebrates the stone rather than simply fitting it into an existing design — considering its shape, colour, proportions and, most importantly, the person who will wear it.

Your stone becomes the starting point for something entirely your own.

And that's how a gemstone found in Bangkok becomes part of your story.

Bespoke Jewellery Crafted by an AUSTRALIAN GOLDSMITH

And that's how a gemstone found in Bangkok becomes part of your story.



From your wish list, to Bangkok, to the jeweller’s bench, to you — every step becomes part of the story behind the piece you’ll wear.

Everything You Need to Know

Is the initial consultation really free?

Yes. Your initial online consultation with me is completely complimentary. It’s a chance for us to talk about what you’re looking for, your preferences and budget, and whether personal gemstone sourcing is right for you.

Do I need to know exactly what gemstone I want?

Not at all. You might come to me knowing exactly what you want, or simply with a colour, shape or feeling in mind. Part of our consultation is turning those ideas into a clear gemstone brief I can take with me.

What does the $300 sourcing fee cover?

The $300 is a professional sourcing fee for my time, expertise and personalised search on your behalf. It covers the creation of your sourcing brief, professional sourcing and assessment of potential gemstones, communication with you throughout the search and guidance through your selection.

Does the $300 come off the price of my gemstone?

No. The sourcing fee is separate from the purchase price of your gemstone and is not credited towards your stone.

How much do I need to spend on my gemstone?

Gemstone prices vary considerably depending on the type of stone, size, colour, quality and other characteristics. We'll discuss your budget during your complimentary consultation so I can establish realistic parameters before I begin searching.

How will I see gemstones while you're in Bangkok?

When I find a stone I believe is worth showing you, I'll send videos and we'll talk about it together. WhatsApp is my preferred platform because it makes sharing videos and having conversations while I'm sourcing simple and immediate.

Do I have to make a decision while you're in Bangkok?

If I find a gemstone you love, you may need to make your decision fairly quickly, as suppliers can’t always guarantee they’ll hold a stone. I’ll share videos and details with you so we can discuss the stone together before you decide.

Having funds ready means that if we find “the one,” we can act promptly to secure it for you.

What happens if you don't find my gemstone in Bangkok?

My search doesn't end when I leave Bangkok. If I don't find a stone that meets your brief during those days, I'll continue searching through my established network of gemstone suppliers.

Can I use the service if I don't live in Adelaide?

Absolutely. The service has been designed to be available Australia-wide, with your initial consultation taking place online.

Can Metal & Stone Jewellers make my gemstone into jewellery?

Yes. If you'd like to take the next step, we can design a bespoke Metal & Stone piece around your gemstone once it has been secured.

What would you like me to find for you?

Your Bangkok Gemstone Search

What would you like me to find for you?


Perhaps you already know exactly what you're searching for.

Or perhaps all you know is that you want something beautiful, meaningful and a little out of the ordinary.

Either way, it starts with a conversation.

Book a complimentary online consultation with me and we'll talk about what you're dreaming of, your ideas and your budget. If you decide you'd like to go ahead, I'll add your personal gemstone brief to my limited sourcing list.Then your wish list comes to Bangkok with me.
