Lab-Created Gemstones

Here at Krikawa, we offer lab-grown sapphires by Chatham, the renowned leader in lab-grown gemstones. A Chatham sapphire is not an imitation but a sapphire grown in a human-controlled environment. Lab-grown sapphires are available in shades of blue, pink, yellow, and champagne. Red (ruby) is also available.

Like our lab-grown sapphires, our lab-grown alexandrite comes from the experts at Chatham. It retains the same properties as its earth-mined counterparts, such as the unique color-changing abilities that can occur in nature. It is eco-friendly as it is not mined from the earth, and best of all, it is significantly more affordable!

Next are lab-grown emeralds, also grown by Chatham. Earth-mined emeralds can get very pricey, which makes the lab-grown alternative a great option for those who do not want to sacrifice quality for budget. In many cases, lab-grown emeralds can be better looking as they have fewer fissures and inclusions that naturally occur in emeralds.

Moissanite is a brilliant white gemstone created in a laboratory and prized for its exceptional optical performance. Originally developed by Charles & Colvard, this distinctive stone has become a premier alternative to diamond for those seeking extraordinary sparkle and durability.

With an exceptionally high refractive index and a hardness exceeding 9 on the Mohs scale, moissanite displays vivid rainbow scintillation and remarkable resistance to wear. Among diamond alternatives, it stands alone in its ability to retain its brilliance and structure over a lifetime of everyday wear.
