Kate & Kole Review 2026: Australian-Made Sustainable Engagement Rings and Fine Jewellery
Finding an engagement ring that looks stunning without contributing to environmentally destructive mining practices used to mean compromising on quality or design. Kate & Kole has changed that equation entirely. This Newcastle-based Australian jewellery studio crafts every piece from recycled gold and lab-grown diamonds, delivering fine jewellery that’s both ethically produced and genuinely beautiful.
Who Are Kate & Kole?
Kate & Kole was founded in 2015 by Sara Spence and Madalynne Clifton in Newcastle, New South Wales. The brand operates as a boutique jewellery studio specialising in bespoke engagement rings, wedding bands, and made-to-order fine jewellery. Every piece is Australian-made, designed and crafted in their Newcastle workshop rather than mass-produced overseas.
What sets Kate & Kole apart from larger jewellery retailers is their commitment to sustainable materials combined with a highly personalised “ring concierge” service. They don’t just sell rings — they guide customers through the entire design process, from initial consultation through to final delivery.
Materials and Sustainability
Every piece from Kate & Kole uses two core sustainable materials:
Recycled Gold: Rather than sourcing newly mined gold, the brand uses recycled precious metals. This eliminates the environmental damage associated with gold mining operations — land disruption, chemical runoff, and carbon emissions. The quality and purity of recycled gold is identical to newly mined gold; the only difference is the environmental footprint.
Lab-Grown Diamonds: Kate & Kole uses lab-grown diamonds that are chemically, physically, and optically identical to mined diamonds. They’re graded using the same 4Cs (cut, colour, clarity, carat) and are indistinguishable from natural diamonds without specialised equipment. The key advantage is that lab-grown diamonds typically cost 30–50% less than equivalent mined stones while avoiding the ethical concerns of diamond mining.
Product Range
Engagement Rings
The engagement ring collection from Kate & Kole includes both ready-to-wear designs and fully bespoke pieces. Popular styles include:
- Solitaire settings — classic round brilliant, oval, and emerald-cut stones in minimalist band designs
- Cluster and halo rings — vintage-inspired designs with surrounding smaller stones
- Bezel settings — modern, low-profile designs ideal for active lifestyles
- Three-stone rings — symbolic past-present-future configurations
Pricing for engagement rings starts from approximately $2,500 AUD for simpler solitaire designs and scales upward based on stone size, setting complexity, and metal choice. Bespoke pieces require a consultation to confirm pricing.
Wedding Bands
Wedding bands are available in 9K, 14K, and 18K gold (yellow, white, and rose), with options ranging from plain polished bands to diamond-set eternity styles. Prices start from around $600 AUD for simple bands.
Everyday Fine Jewellery
Kate & Kole also offers a range of everyday pieces including birthstone bracelets, signet rings, pendant necklaces, and stacking rings. These make excellent gifts and are priced more accessibly, typically between $200–$800 AUD.
The Bespoke Design Experience
The bespoke process at Kate & Kole follows a structured approach:
- Initial consultation — available in-person at the Newcastle studio or via video call for customers elsewhere in Australia. You discuss preferences for stone shape, metal type, setting style, and budget
- Design development — the team creates detailed CAD renders for review and refinement
- Stone selection — you choose from a curated selection of lab-grown diamonds or gemstones, with full 4C grading certificates provided
- Production — the piece is handcrafted in the Newcastle workshop, typically taking 4–6 weeks
- Delivery — shipped in eco-friendly packaging with full insurance
Customer reviews consistently highlight the communication quality throughout this process. The team provides regular updates and is responsive to questions, which matters enormously when you’re investing in something as significant as an engagement ring.
Quality and Craftsmanship
Having examined multiple Kate & Kole pieces, the craftsmanship is genuinely impressive for a boutique operation. Stone settings are secure and precisely aligned, metal finishing is smooth with no rough edges, and the overall weight and feel of pieces sits comfortably in the premium category.
The brand uses Australian hallmarking standards, and all pieces come with a certificate of authenticity detailing the materials used. Lab-grown diamonds are accompanied by independent grading reports from recognised laboratories.
How Kate & Kole Compares to Competitors

Kate & Kole occupies a distinct position: more personalised and sustainably focused than chain retailers, but more accessible than high-end traditional jewellers. The Australian-made aspect is a genuine differentiator — very few engagement ring brands at this price point manufacture domestically.
Shipping, Returns, and Aftercare
Kate & Kole ships across Australia with full insurance coverage. Ready-to-wear pieces typically dispatch within 3–5 business days, while bespoke orders take 4–6 weeks from design approval.
The brand offers complimentary ring resizing within the first 12 months, and a lifetime cleaning and polishing service for all pieces. Given that ring sizing can be tricky when ordering online, the resizing policy provides meaningful peace of mind for customers who can’t visit the Newcastle studio in person.
Who Is Kate & Kole Best For?
- Eco-conscious couples who want verified sustainable materials without sacrificing design quality
- Bespoke seekers who value a personal design experience over choosing from a display cabinet
- Supporters of Australian manufacturing who want to know exactly where their jewellery is made
- Lab-grown diamond converts who want a beautiful stone at a significantly lower cost than mined equivalents
Frequently Asked Questions
Can I visit the Kate & Kole studio?
Yes. The studio is located in Newcastle, NSW, and accepts appointments for in-person consultations. For customers outside Newcastle, Kate & Kole offers comprehensive virtual consultations via video call.
How long does a bespoke engagement ring take?
Typically 4–6 weeks from design approval to delivery. Rush orders may be accommodated depending on workshop capacity — contact the team directly to discuss timelines.
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds have the same chemical composition (pure carbon), crystal structure, and optical properties as mined diamonds. They’re graded using the same international standards and are permanent — they won’t cloud, fade, or change over time.

Kate & Kole offers Afterpay and Zip for eligible purchases, allowing you to split the cost into instalments. For bespoke pieces, deposit and progress payment structures are available.
