HELMUT the Jeweler: Where Chatham's Lab-Grown Colored Stones Shine

Chatham: The Pioneer of Lab-Grown Gemstones

These gemstones have the same physical, chemical, and optical properties as mined gems do. They don’t “make” gems. They control the environment so that crystals can grow naturally, recreating the conditions in which gems grow in the earth.

Lab-Grown Gemstones at HELMUT the Jeweler
Gem Crystals in a laboratory

The process of growing gem crystals in a laboratory rather than mining them is a bit like making ice in your freezer instead of finding it in a lake.

You place the starter material, water, in a container, and put the container into a controlled environment: your freezer. Create the right conditions of temperature and time and ice crystals will form. The freezer ice will usually be cleaner and purer than lake ice because you can carefully control the environment. But it’s still ice, just like the ice that forms in nature. Same thing with lab-grown gemstones.

Remember, lab-grown gemstones are 100% gemstone. The only difference between lab-grown gemstones and mined gemstones is where they form: in the earth or in the lab.

For your peace of mind, there is a Lifetime Warranty for all Chatham lab-grown gemstones and a Certificate of Authenticity for Chatham jewelry pieces.

Like diamond itself, growing these brilliant crystals is extremely hard.

Despite the difficulty and effort required, lab-grown gemstones sell for less than mined gems of the same quality. Depending on the size and weight, you could save thousands of dollars by choosing a lab-grown gemstone. Chatham lab-grown gemstones can’t be distinguished from mined gemstones except with sophisticated gemological equipment. This is the reason we provide their lab-grown gemstones at HELMUT The Jeweler.
