Sourcing Diamonds & Gemstones: Exceptional Stones for Bespoke Jewellery
Expert Gemstone Sourcing for Your Custom Creation
Finding the perfect diamond or coloured gemstone is at the heart of every bespoke piece we create at Sara Handmade Jewellery. With deep industry connections and a gemmologist’s eye, we source exceptional diamonds—including GIA-certified and lab-grown options—as well as rare coloured gemstones such as Ceylon sapphire, Australian teal sapphire, rubies, emeralds, and more. Whether you’re seeking a centrepiece for an engagement ring or a meaningful addition to your jewellery collection, we’ll help you discover a stone that reflects your style and story.
Our Approach: Quality, Ethics & Expertise
We believe that every gemstone should be as responsibly sourced as it is beautiful. Our longstanding relationships with trusted dealers in Australia and worldwide allow us to access premium stones while upholding strict ethical standards. We prioritise:
Responsibly Sourced Gemstones: Supporting fair labour, environmental stewardship, and conflict-free practices.
GIA-Certified Diamonds: For larger diamonds, we use only GIA-certified stones for your peace of mind and investment security.
Lab-Grown Diamonds: Offering a sustainable, modern alternative with the same brilliance and durability as natural diamonds.
Upcycling & Remodelling: We can repurpose gemstones from your old or sentimental jewellery, creating new pieces with history and heart.
