About Custom Fine Jewellery
Your Story, Set in Gold
I don’t just make jewellery - I help you tell your story. Every piece I design is meant to feel personal, not just trendy. If you want something that lasts, something you’ll actually wear and maybe even pass down, you’re in the right place.
How We Create Together
- First, we sit down and chat. I want to know your style, your story, and what this piece means to you.
- We sketch ideas together, mixing your inspiration with my design sense.
- I’ll show you a range of gemstones till you find the one that feels right.
- Every detail gets discussed, tweaked, and perfected. No surprises.
- When it’s ready, you get to try it on. That moment is always special.
Jewellery That’s Meant to Be Worn
I see too many beautiful pieces locked away. My focus is on comfort and versatility, especially for brides. Grand look, light feel - so you can actually enjoy your big day. Many of my bridal necklaces are detachable, so you can wear them in different ways for different occasions.
What I Make
- Bespoke engagement rings for every kind of love story
- Statement gemstone rings with emeralds, tanzanites, sapphires
- Elaborate, multi-layered necklaces (detachable for future wear)
- Bracelets and bangles, from dainty chains to bold diamond kadas
Craftsmanship You Can Trust
Every piece is made by Indian master artisans, finished to international standards. I’m all about transparency and quality. If you want heirloom jewellery design that’s truly yours, let’s make it happen.

My Story
Hey, I’m Prachi, started Astu because jewellery is not just bling for me. It’s memories, stories, sometimes even a bit of you. I love sitting with people, hearing about their lives, sketching together till we find that one design that just feels right. Whether it’s a big bridal set or a tiny ring, it should feel like yours. I want you to wear it, live in it, pass it on.
My Work
Custom-crafted luxury jewellery - I make engagement rings, cocktail rings, earrings, bracelets, bridal sets with coloured gemstones and diamonds.
Personal jewellery design experience - Every piece starts with a one-on-one chat with me, from your ideas to picking gems and sketching together.
Minimal wedding jewellery for modern brides - I guide brides to pick comfy, versatile pieces—no more heavy earrings or chokers ruining your fun.
Detachable bridal necklace set and more - Many designs, like the Heera Panna set, have layers you can detach or style for any occasion.
