Slate & Tell's Lab-Grown Diamonds (also known as lab-created diamonds, man-made diamonds, engineered diamonds, and cultured diamonds) are chemically, physically, and optically identical to natural diamonds. These Lab-Grown Diamonds are real diamonds that are created in a laboratory setting using advanced technological processes, making them significantly less expensive and more sustainable.

Our lab-grown diamonds are hand-selected with a Color of H-I and Clarity of SI1-SI2 and are cut with precision to display brilliance from all sides. Ranking 10 on the Mohs scale of hardness Lab Grown Diamonds create a superior center stone option for all engagement rings as they maintain the same sparkle and durability as a mined diamond.


First discovered in 1893 by a French scientist, Henri Moissan in Arizona, Moissanite is a near-colorless gemstone that's composed of silicon carbide. Moissanite is extremely rare to find in nature, therefore the Moissanite we know today is lab-created. Compared to mined diamonds, lab-created Moissanite gemstones have a different chemical makeup & have a smaller carbon footprint, resulting in less negative environmental impact. They are a popular diamond alternative stone because of their impeccable resemblance and durability for everyday wear. Not only do they have a striking resemblance to real diamonds, but they're also extremely affordable, allowing you to get the engagement ring and carat size of your dreams.


Slate & Tell's brilliant Cubic Zirconia gemstones are a stunning diamond simulant. Most of our jewelry styles are available with this affordable and ethical choice to enhance our mining-free options. Many of our engagement rings and wedding band styles are hand set with our white cubic zirconia, providing you with a luxurious appearance at the fraction of the price.

GENUINE TANZANITE Slate & Tell's Tanzanite gemstone has a stunning fire and brilliance with colors ranging from royal blue to deep blue hues.
