Share
Jewellery has always been more than just an adornment — it’s an expression of identity, memories, and milestones. In today’s world, where individuality is celebrated, custom jewellery is becoming the choice of modern women and men who seek pieces as unique as their stories.
At ASTU Jewellery, founded by Prachi Sanghvi in Mumbai, bespoke design is more than a service — it’s a philosophy. With roots in a family jewellery legacy, combined with expertise in architecture, gemology, and design, Prachi reimagines the traditional family jeweller into a modern bespoke studio where heritage meets contemporary elegance.
What is Custom Jewellery?

Custom jewellery refers to pieces designed and crafted exclusively for you. Unlike ready-made jewellery, it reflects your personality, preferences, and lifestyle. Whether it’s a custom diamond engagement ring, a personalised bracelet with gemstones, or a necklace that tells your story, every detail is thoughtfully created to suit your individuality.
At ASTU, every bespoke piece is handcrafted by master artisans, transforming sketches and ideas into timeless, wearable works of art.
The Process of Custom Jewellery at ASTU
The custom jewellery process is deeply collaborative and personal. Here’s how it works:
-
Consultation & Inspiration – Share your story, preferences, and inspirations with the ASTU design team.
-
Design & Concept Creation – From sketches to CAD designs, you’ll see your vision come to life.
-
Gemstone Selection – Choose from ethically sourced diamonds, pearls, sapphires, emeralds, tourmalines, tanzanites and more.
-
Craftsmanship – Skilled artisans handcraft your piece in gold, diamonds, or mixed gemstones.
-

This process ensures every ring, bracelet, bangle, necklace, earring, daily wear and bridal set is a reflection of who you are.
