Lab-grown diamonds have become one of the most popular choices for engagement rings and for good reason. They share the same physical, chemical, and optical properties as mined diamonds, often at a significantly lower price point. But a question we hear constantly at Jacob Mercari is: "How do I know I'm getting a quality stone?"

The answer comes down to grading and certification. A certified diamond lab-grown or natural has been independently evaluated by a gemological laboratory and issued a report detailing its characteristics. Understanding what that report means is the difference between buying with confidence and buying blind.

Here's exactly how lab-grown diamonds are graded, which certifications matter, and what to look for when reviewing a diamond report.

A natural diamond is formed deep within the earth over an extraordinary amount of time. No two are exactly alike, which means every natural diamond has its own fingerprint of brilliance, character, and history.

That uniqueness is part of the appeal. A natural diamond engagement ring is not just beautiful because it sparkles. It is beautiful because it feels permanent. It has presence. It has romance. It has that quiet, confident energy of something that does not need to explain itself.

Think of it this way: a natural diamond is the jewellery version of a perfectly tailored black blazer. Timeless. Versatile. Always appropriate. Somehow even better with good lighting.

A New Jacob Mercari Guide 💍 more on our blog ! https://jacobmercari.com/blogs/our-blog/sapphire-colours-a-guide-to-everyday-sapphire-jewellery-engagement-rings

Sapphires are one of the most loved gemstones in fine jewellery, and for good reason. Elegant, durable, meaningful, and available in a breathtaking range of colours, sapphires are far more versatile than many people realize.

While most people immediately picture a deep royal blue stone, sapphires can be found in almost every colour of the rainbow. From soft pink and romantic peach to rich green, golden yellow, violet, white, and the rare colour-changing varieties, sapphires offer endless possibilities for personal, everyday jewellery and one-of-a-kind custom engagement rings.

At Jacob Mercari, we love sapphires because they combine timeless beauty with everyday practicality. Whether you are designing a custom ring, choosing a meaningful pendant, or looking for a colourful gemstone piece you can wear daily, sapphire is always a beautiful choice.
