This listing is for a custom-made Winza sapphire ring. These are my rose cut Winza sapphires, with flat bottoms and a rising faceted formation on their faces. Sapphires from Winza, Central Tanzania, are a very distinctive bicolour mix of purples, deep blues, and hot reddish pinks. They are often included, and these sapphires do have internal inclusions such as veils. If you would like to see any of the sapphires up close, just let me know.

You can choose the colour of 14k gold you'd like your ring in (rose, white, or yellow), as well as the texture on the band. Please see the photos of Stone 1 balanced on my finger; this is an example of the type of band this ring will be built of.

You also choose your stone's setting, which can be a bezel (faceted texture or smooth) or a hand-built prong setting. Please see my other work if you are not familiar with my distinctive style of building prong and bezel settings. Or, ask for example photos- I will be happy to oblige.

Want a different type of band? I have photographed the sapphires alongside a 14k rose gold twig, as well as a round-profile 1.5mm wide gold wire. Anything is possible- I build these rings by hand in the studio, so let me know if you'd like a different sort of a band. You can also request pricing on rings that include gold granulation or smaller bezel set accent stones.

Frequently Asked Questions

Custom and personalized orders

I am always open to hearing your design ideas. Please contact me through the shop, or at to discuss design possibilities.

Sizing details

If you are unsure of your ring size, the best way to be sized accurately is by visiting two commercial jewelers. Please ensure they size you using their thin sizing tools- not the wide band sizing tools, nor by having you try on rings from their display.

If any questions arise around being properly sized, I am always happy to help- contact me through the shop, or at

Gift wrapping and packaging

I don’t provide a gift wrapping service. Rings and earrings ship in jewelry boxes that are hot foil stamped with the Specimental logo.

If the person for whom you are purchasing the piece shares your address, please be aware of the following: International export law dictates that the detailed contents of packages, and their value, be clearly marked on the outside of the package. This means that if they see the package before you do, they can easily tell what they are being gifted with.

Need secrecy for this delivery? The very best option is to have your package held for you at your closest Fed Ex store- if you are unsure of its location, I'm happy to help.

What about repairs and upkeep of your new jewelry- how does Specimental provide ongoing customer support?

Our hands are busy objects, and any ring worn on a finger can become accidentally damaged. All rings need regular maintenance. Make sure you are buying your raw diamond ring from a jeweler with the knowledge and experience needed to ensure your stone stays put. Ask them about their warranty and their repair/upkeep policy. Look at how frequently they work with raw diamonds, and assess whether they have the technical experience to create a ring that will last your lifetime.
I stand behind each piece of jewellery I make. If something goes wrong with your ring, at any time- you slam your finger in a drawer and crush the band, you break a prong, you smash and crack your stone- you can count on me to support you with the repair.

Recycled Gold

My gold is all recycled- the metal plant I purchase it from has been in business for over 100 years. They smelt their metals to the highest environmental standards, to cause the least impact on the environment. They do not deal with newly mined metals, as these metals cause much greater destruction to the environment.

There is no visible difference between recycled metals and newly-mined metals. There is also no difference as far as the karat of the metals go- 18k recycled gold is exactly the same in constitution as 18k newly mined gold. The vast majority of my clients prefer their metals recycled, as environmental impact is of concern when choosing the perfect piece of jewelry.

Can Specimental reuse my old stones and recycle my gold?

I can use your heirloom stones in a new design. The stones must be pulled from their settings and checked for stability by a professional jeweler prior to shipping them to me. I cannot recycle your gold. I am not set up to smelt gold in the studio, so am not able to melt down your old gold pieces for you.

Rush Orders

My current production times are listed in my shop announcement. If you need something more quickly, please get in touch via the shop, or at

Depending upon my work and family schedule, I am happy to accommodate your rush orders. There is no additional charge for a rush order. However, please do get in touch prior to ordering to discuss your deadline with me.

Can I order a ring with a different stone, wider band, different texture, or in a different colour/karat of gold?

Yes! All of my pieces are completely hand fabricated in the studio by me, from raw materials. I am able to create any of my designs with any stone, in any composition. In short, you can have your ring absolutely any way you like it. Contact me through the shop, or via to get the discussion around your perfect piece of jewelry started.

Why buy your raw diamond ring from Specimental?

A raw diamond is an exceptionally difficult stone to set properly. Their unique shape means that a custom setting needs to be fabricated for each and every stone. The way in which the setting is closed around the diamond must be approached in a very particular fashion.

I began setting these stones into my rings in 2009, when only a small handful of jewelers were working with this type of stone. As the appeal of raw diamonds has exploded, countless numbers of jewelers are now incorporating them into their designs. I have set thousands of raw diamonds into my pieces since then.
