Platinum is a naturally white metal that stays white for life - it doesn't require replating and is denser and more durable than gold. White gold is yellow gold alloyed with white metals and coated in rhodium to achieve its bright white finish, though this coating may need refreshing over time. Platinum is typically the premium choice for engagement rings worn daily.

Rhodium is a precious metal from the platinum family used to plate white gold jewelry. It gives white gold its bright, mirror-like finish and adds a protective layer that resists scratches and tarnish. Over time, rhodium plating can wear and may need to be reapplied, a simple, low-cost service available at most jewelers.

You can find your ring size using our free ring size guide on the website. We recommend measuring your finger at the end of the day when it's at its largest, and avoiding cold conditions when sizing. If you're unsure, our team can assist, and every Precious Carbon ring comes with a free resize after purchase, so there's no pressure to get it perfect the first time.

A laser inscription is a microscopic identification number engraved on the diamond's girdle (outer edge) using a precision laser. This number corresponds directly to your diamond's grading report from GIA or IGI. It's your proof of authenticity, confirming that the diamond you purchased is the exact stone in your ring.

Every diamond we sell comes with a GIA or IGI grading report that includes a unique report number. If the diamond has a laser inscription, that number is also engraved directly on the stone. When your jewelry arrives, you can verify the inscription matches your report. This gives you complete confidence that the diamond you selected is the one you received.

Yes. Every Lab Diamond & Natural Diamond listed on Precious Carbon comes with a grading report from either GIA (Gemological Institute of America) or IGI (International Gemological Institute), the two most trusted independent certification bodies in the industry.

We stock a carefully curated selection of diamonds across a wide range of grades, from excellent everyday options to exceptional investment-quality stones.

For regular maintenance, gently clean your jewelry using warm water, a small amount of mild dish soap, and a soft-bristle toothbrush. Rinse thoroughly and pat dry with a lint-free cloth. Avoid harsh chemicals, ultrasonic cleaners for certain gemstones, and chlorine exposure. For a deeper clean, visit a local jeweler for a professional polish. We also recommend an annual professional inspection to check prong integrity.
