Signature Custom Jewellery Collections
I combine architectural precision with a love for rare gemstones to create pieces that are yours alone. Every design here begins with a conversation about your style.
This bridal masterpiece features a symphony of cushion, oval, and pear-shaped amethysts, crowned with 15 carats of brilliant round-cut diamonds. It is designed to shimmer with a regal grace that feels both grand and personal.
I believe jewellery should adapt to your life. This versatile diamond necklace demonstrates how a single piece can be layered for a grand look or detached for simpler, elegant wear, ensuring it is cherished for all occasions.
The Raiya Cocktail Ring is designed to be a center of power and light. It features a stunning 7-carat round brilliant diamond in a cluster setting that captures attention from every angle.
Every love story is unique, and so should be the ring that symbolizes it. This collage showcases a custom-designed heart-shaped diamond ring, a testament to how we can bring your personal vision to life.
This is my most-loved icon, the Crimson Royal earring. It is a regal composition of ruby, amethyst, citrine, pearls, and diamonds, woven together to create a piece of pure royalty for your collection.
To show that diamonds can be both classic and modern, I designed this set using fancy cut diamonds set in bold black rhodium. It’s a contemporary take on bridal jewellery, designed for the woman who wants to stand apart.
This Ruby Clover bracelet is a perfect example of wearable luxury. It combines the vibrant color of round-cut rubies with the sparkle of marquise diamonds, creating a piece that is both delicate and striking.

About Featured
Before any metal is cast, we sit down to sketch. I treat every piece as a personal project, ensuring the design balances grand aesthetics with the comfort you need for daily wear. Whether you have a specific vision for an engagement ring or want to reimagine an heirloom, we refine the concept together until it feels like a natural extension of your personality.
As an architect turned gemologist, I approach jewellery design with a structural eye. My work at Astu is built on the belief that jewellery should not sit in a locker, but be a part of your life. This is why I focus on modular designs, such as necklaces that detach into chokers or pendants, giving you multiple looks from a single investment. Every custom item undergoes a rigorous design phase. We begin with one-on-one consultations to understand your aesthetic, followed by 3D CAD renderings so you can see the final shape before production. We use high-quality gold and ethically sourced gemstones, from Zambian emeralds to brilliant-cut diamonds. My studio in Worli is where these ideas take shape, crafted by master artisans who share my dedication to detail. If you are looking for an engagement ring that speaks to your story or a bridal set that blends tradition with modern comfort, let's connect and begin sketching your design.
