Cosmic Burst Diamond Necklace
Ready to add some ethereal sparkle to your wardrobe? A burst of starlight captured in gold, the Cosmic Burst Diamond Necklace glimmers like a constellation resting gently at your collarbone.
Eight round brilliant-cut white diamonds shimmer in a random pavé-setting, each stone a spark in orbit. Their light gathers in an 11mm pendant of solid 9 karat yellow gold, polished to a mirror-bright finish that catches each fragment of day and night.
Suspended from a fine 42-45cm gold chain and secured with a classic parrot clasp, this 9 carat diamond necklace rests effortlessly against the skin, elegant enough for evening, radiant enough for everyday.
Handcrafted in our Melbourne jewellery store using 100% recycled 9 karat gold and ethically sourced diamonds, it embodies Black Finch’s commitment to conscious beauty.
Wear it as a reminder that the universe’s brilliance is never out of reach. A cosmic necklace that celebrates light in its purest form.
Made to Order. Please allow 8 to 10 weeks for production.

Loved By Those Who Wear Us
This is my second piece of Black Finch teal sapphire jewellery and oh, how I LOVE these earrings. Stunning design, beautifully weighted and crafted with respect to sustainability and ethical practice.
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.
