Lab - Created gemstones

Eco-Friendly Gemstones
for the Environmentally Conscious

A lab-created gemstone holds the same physical, optical, and chemical properties as its earth-mined counterparts; however, it is grown in a lab rather than in the earth. In addition to their environmentally friendly attributes, lab-grown gemstones are more affordable than earth-mined gemstones!

Lab-Created Sapphires

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.

Lab-Created Alexandrite

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!

Lab-Created Emeralds

Last, but certainly not least, 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.
