Astro Star Sign Signet - Capricorn
December 22 to January 19
Earth. Cardinal.
Burn the colour of Garnet. Harness the energy of the goat. Expect more from those who drain you.
Capricorn carries the weight of mountains and the patience of ancient stone. This Capricorn ring is made for those who understand that true luxury is never hurried.
Engraved with the Capricorn star constellation, each signet bears a map of the night sky as it has always been, timeless and unwavering. The organic texture catches light the way weathered granite does, with depth and grounded authority, while the matte finish lends the piece an understated richness that speaks to Capricorn's instinct for the enduring over the ephemeral. Crafted in solid gold, this is a ring built not for a season but for a lifetime.
Handcrafted by our expert jewellers in Melbourne, the Astro Signet series is an exercise in intentional making. Each of our signet rings begins with 100% recycled gold and an ethically sourced 1.5mm pink sapphire, and two conflic-free 1.3mm white diamonds, shaped by artisan hands. At 1.7mm, the band sits close and assured, a Capricorn signet ring scaled for daily wear without ever sacrificing its sense of occasion.
Wear it as a declaration of who you are and where you are headed, or pass it forward one day as a piece of family history still in the making. Some rings are simply jewellery. This one is a relic of ambition, worn with intention.

Loved By Those Who Wear Us
I commissioned a charm from Black Finch in early 2025 and it's one of the things I most treasure in the world. The team was so responsive and understood perfectly what I was looking for, and the finished product was absolutely divine.
My engagement ring is truly a piece of art so I didn’t know what to do for my wedding band, so I decided to get a different style for my other hand and it’s so perfect. Can’t thank the team enough for sapphire perfection.
The team at Black Finch are exceptional at what they do. My partner purchased my engagement ring here and we most recently had my wedding band made to match! The staff are friendly and prompt and the jewels themselves are to die for.

Sustainability
Each Black Finch piece is handcrafted in our Melbourne studio using 100% recycled refined gold, eliminating the need for new mining. We ethically source traceable sapphires and conflict-free diamonds that adhere to the Kimberly Process Certification.
