Lab - Created gemstones

Eco-Friendly Gemstones
for the Environmentally Conscious

A lab-created gemstone holds the same physical, optical and chemical properties as their earth mined counterparts, however, they are grown in a lab and not in the earth. In addition to their environmentally friendly attributes, lab-grown gemstones are more affordable than earth mined gemstones!

Lab-Created Sapphires

Vintage Scalloped Halo Engagement Ring with Chatham Pink SapphireHere at Krikawa, we offer lab-grown sapphires by renowned leader in lab-grown gemstones, Chatham. 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 Emeralds

Infinity Leaf Diamond Engagement Ring with Lab-Created Emerald Center StoneLast, 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 less fissures and inclusions that naturally occur in emeralds.

Lab-Created Moissanite


Moissanite is a white stone that is also grown in a lab.  Created by Charles and Colvard, this unique white stone is a perfect alternative to diamonds.

With a high refractive index and a hardness over 9, they are the only diamond alternative that has rainbow scintillation and can last a lifetime without abraiding.
