Yes. Every Luma Carat diamond ships with an independent IGI certificate confirming its cut, colour, clarity, and carat weight, so you can shop with full confidence.

If you're unsure of your size, order your best estimate — our team can help confirm or adjust it after purchase. Comparing a ring you already own against a standard sizing chart is also a reliable way to check.

Our pieces are available in 14K white and yellow gold. If you're looking for a different karat or rose gold, reach out and we'll confirm availability for your chosen design.

Orders are prepared with care and shipped fully insured across India. You'll receive tracking details as soon as your order leaves our workshop.

Contact us before placing your order if you anticipate needing a resize, and our team will guide you through the process. See our return policy for full details on eligibility.

Yes, every diamond comes with its IGI certificate included at no extra cost, so authenticity and quality are always verified.
