- 1 · Match a card
- 2 · Measure a ring
- Wrap a thread or a thin strip of paper once around the base of your finger, snug but not tight.
- Mark where it meets, then lay it flat against a ruler.
- Type the length here, in millimetres.
Measure at the end of the day, when fingers are a little larger, and check the ring will slide over your knuckle.

Good
questions.
Are lab-grown diamonds real diamonds?
Yes. A lab-grown diamond is carbon crystallised the same way as a mined one, with the same hardness, sparkle and chemistry; only its origin differs. Every one we use is graded by IGI and laser-inscribed. Natural diamonds are available in the atelier above, with an IGI or GIA report.
Is the gold hallmarked?
Every piece is 18K gold (75% pure) with a BIS hallmark and a six-digit HUID, which you can verify yourself on the BIS Care app.
What if the ring doesn't fit?
Use the sizer above, or ask on WhatsApp and we will post you a free ring sizer first. If a ring still doesn't fit, we resize it free within 30 days of delivery.
How is it delivered?
Fully insured, in plain outer packaging, and handed over only with an OTP. Pieces from the collection ship the next working day and arrive in 2 to 6 days depending on your pincode. Custom rings take 15 to 20 days to make.
Can I return or exchange it?
Unworn pieces can be returned within 15 days for a full refund. Engraved and custom pieces can't be returned, but any piece can be exchanged at any time for the full value of its gold.
How do I pay?
By UPI straight to us, and your order is confirmed on WhatsApp. For larger amounts we share our bank details for a transfer instead. The invoice follows with the tracking number.
Can you make my own design?
Yes. Start with the ring designer above, or send a sketch or a photo on WhatsApp. We send a 3D render to approve before anything is cast.
