Our Story

A father's craft.
A son's vision.
A diamond's story.

For 25 years, our atelier in Mumbai has crafted diamond jewellery one piece at a time — quietly, and for those who knew where to find us. Today, as Astera, we open those doors to the world — bringing the same artistry to those who believe every diamond should carry meaning.

We work with both natural diamonds and lab-grown diamonds. Same brilliance. Same fire. Same uncompromising standard.

What We Craft

Made by hand, made for you.

Solitaires

The single diamond. The infinite promise. Engagement rings handcrafted around stones of exceptional quality.

Bridal

Heirloom sets crafted for the most important day — and every day that follows. Necklaces, earrings, and statement pieces.

Lab-Grown

Same diamond. Same brilliance. Lighter footprint. Conscious luxury for the modern collector.

Bespoke

Bring us a sketch, a memory, an heirloom. We design and craft it from scratch — entirely by hand in Mumbai.

Craftsmanship

23 seconds
to set a diamond.
23 years to learn how.

Every Astera piece is set by hand in our Mumbai atelier. No automation. No shortcuts. Just the patience of a craftsman and the precision of decades.

We work with IGI- and GIA-certified stones, and provide certification with every piece — because what we sell is more than jewellery. It is trust.
