Since starting Glasswing Jewellery I have been commiTted to only buying gemstones from suppliers that I can be confident are truly ethical in their sourcing, AND THROUGH all aspects of the supply chain.


The reality of that decision, until recently, has meant I have essentially only been able to access and work with a tiny fraction of the gemstones that exist in cut, or uncut form, in the world.

The good news is that I can now source more gemstones than ever from ethical suppliers here in the UK and abroad. More and more are becoming available as suppliers are becoming increasingly aware of the need to be socially and environmentally responsible in the the way they do business.



Recycled Diamonds

I source recycled diamonds from the 'Harmony' diamonds range at the eco-friendly bullion dealer Hoover & Strong.  They are arguably the most eco-friendly natural diamond available and, by demanding them, customers and jewellers are helping to reduce the industry's reliance on environmentally damaging mining practices. 

Hoover & Strong is one of the world's leaders in the acquisition and reintroduction of these many millions of diamonds back into the jewellery supply chain. A recycled 'Harmony' diamond is an originally naturally occurring diamond, cut and polished from mined rough stones, recovered from vintage jewellery, re-polished and graded for the perfect non-conflict, non-polluting option. 

A huge selection of sizes, grades and colours are available, so tell me what you'd like and I will find the perfect diamond/s for your ring.

Canada Mark Diamonds

The CanadaMark assures the end consumer of the integrity of the supply chain. These Canadian diamonds can be traced from the mine to the retail outlet. Thus ensuring peace of mind for the end consumer, guaranteeing they are natural and untreated. The whole process can be tracked through an audited process at every stage from country of origin to the polished stone.

Lab-Grown Diamonds

Lab grown diamonds are created using advanced technology — either extreme pressure and heat or a carbon vapor deposition process which replicate the natural method of diamond formation. The result is lab grown diamonds which have the same characteristics of natural ones, both in strength and sparkle. Lab grown diamonds present a new, technologically advanced and sustainable alternative to mined diamonds. All of my lab grown diamonds are certified.


Ethical Gemstones

Some of the ethical gemstones I can source for you:

Sapphires, Spinel, Moissanite, Moonstone, Tourmaline, Topaz, Garnets, Rhodonite, Smoky Quartz, Rose Quartz, Green Quartz, Iolit Rubies, Aquamarine, Peridots, Citrine, Purple Sage Chalcedony, Blue Zircon.

I can also occasionally source ethical or antique recycled emeralds.

If you would like a particular stone not mentioned there is a chance I will be able to source it for you. 

It’s always worth dropping me a line through the contact page so I can see if it has become available.


using your own precious materials

If you have your own heirloom piece with gemstones or diamonds, that you’d like remodelling or incorporationg into a new piece of jewellery, I may be able to work with you, this will depend on the individual piece and your original items. Please get in touch through the commission form to discuss your requirements.

Similarly, using your own gold may be possible, although most often it is preferable to use the value of it against your new jewellery because of some of the technical complications and labour involved.
