“I want to help keep alive the love for exquisite jewellery that reflects beauty, romance and connection.”


Collective Designs is inspired by beauty, romance and connection. It starts with the allure of the gems and metals that are passionately crafted into exquisite pieces that move people to possess them and create a unique emotional bond.

This tale of creation and emotion is Collective Designs’ essence. Founder Heidi Plentinger is passionate about this connection between jewellery and people. Especially the emotional link, usually romance, that creates a link with the piece that is ever lasting.

With this in mind, she created Collective Designs to connect independent-owned jewellery retailers and discerning clients with pieces they can fall in love with as a designer, jeweller, wholesaler, retailer or customer.

For business owners, Heidi has an array of services as a consultant, locum, designer, wholesaler and agent to help enhance your stores to stand out in the marketplace.

As for customers, she works directly with you to design beautiful bespoke and one-off creations from existing jewellery or new materials into sentimental pieces.

Heidi’s jewellery journey, started more than three decades ago in the family store. She fell in love with the industry, as it was a way to express her creative side as a dancer and artist. This discovery continued as Heidi worked across every aspect of the industry from retail to wholesale to design in Australia and overseas.

Along the way, she completed several courses from jewellery drawing to gemmology including the GIA Colour Grading Certificate; curated the final De Beers Collection in Australia; worked with Peter Gerrard, Nic Cerrone, Makers Mark Gallery; and established Mark Milton’s Australian presence.

With such an overarching industry background, Heidi decided to bring her expertise, skills and passion together and establish Collective Designs.
