An Affordable Option

That puts more sparkle and shine within reach

While our commitment to natural diamonds spans a century and remains unchanged, we understand the diverse preferences and budgets of our guests. Along with our incomparable RB Select natural diamonds, for over a decade we’ve offered a curated collection of premium lab-grown diamonds from respected growers like Phoenix, certified by SGS for sustainable production. Hand-selected for beauty, sparkle, and shine, our loose lab-grown diamonds adhere to the same exacting standards as our RB Select natural diamonds.

What are Lab-Grown Diamonds

Lab-grown diamonds are cultivated in controlled laboratory environments using modern technologies and techniques. These diamonds possess the same physical, chemical, and optical properties as traditionally mined diamonds—but without the unique inclusions and extraordinary attributes created by nature.

Why Choose a Certified Lab-Grown Diamond?

Accessible, abundant, and chemically identical to natural diamonds, lab-grown diamonds provide a more affordable choice for those seeking a reasonably-priced option. However, it's important to note that while lab-grown diamonds may be more cost-effective, they lack the rarity, distinct characteristics, and earth-bound inclusions that make natural diamonds so extraordinary.

Quality & Consistency

Lab-grown diamonds are created in controlled laboratory conditions, ensuring a consistent and predictable supply. This means that lab-grown diamonds have uniform quality, attributes, and features—making them a reliable choice when searching for a cost-effective option. However, it is important to note that lab-grown diamonds lack the allure and mystique of natural diamonds, as they are neither rare nor distinctive.
