Getting to know your gem
Every gemstone we set is lab grown, with the same chemistry, color, and character as its mined counterpart. This guide walks through the stones we work with most often, what makes each one unique, and how to care for it.
The stones
A closer look at our lab grown gemstones
Lab grown diamond
Hardness 10
The hardest material on earth, grown in a controlled lab environment. Chemically, physically, and optically identical to a mined diamond, and independently certified.
Lab grown sapphire
Hardness 9
Grown with the same corundum structure as a mined sapphire. Best known in deep blue, but available in nearly every color except red.
Lab grown ruby
Hardness 9
Grown with the same corundum structure as a mined ruby, colored a vivid red by traces of chromium. Bold, warm, and built to last generations.
Lab grown emerald
Hardness 7.5 to 8
A rich green variety of beryl, grown rather than mined. Valued for its color above all else, with the same natural-looking internal character.
Lab grown alexandrite
Hardness 8.5
A color-changing stone that shifts from green in daylight to a reddish-purple under warm light. Rare in nature, more accessible when grown.
Lab grown morganite
Hardness 7.5 to 8
A soft pink variety of beryl, the same family as emerald. Gentle, romantic, and increasingly popular in engagement rings.

Keeping it brilliant
Caring for your gemstones
01
Clean gently
Warm water, a drop of mild soap, and a soft brush keeps most gemstones looking their best. Avoid harsh chemicals and ultrasonic cleaners on softer stones like emerald and opal.
02
Store separately
Keep pieces in individual pouches or a lined box so stones don't scratch each other, especially harder gems against softer ones.
03
Remove before impact
Take jewelry off before workouts, swimming, or household chores. Even the hardest stones can chip from a hard knock.
Common questions
Good to know
Is a lab grown gemstone a real gemstone?
Yes. A lab grown gemstone has the same chemical composition, hardness, and optical properties as its mined counterpart. The only difference is where it was formed.
What's the difference between a gemstone's color and its clarity?
Color is the hue and saturation of the stone itself. Clarity refers to internal characteristics, called inclusions, that are unique to each stone and don't affect its structural integrity.
Are lab grown gemstones as durable as mined ones?
Yes, durability depends on the stone type, not how it was formed. Lab grown sapphire and ruby are nearly as hard as diamond and hold up well to daily wear, while lab grown emerald needs a bit more care, just like its mined equivalent.
Is every gemstone certified?
Every lab grown gemstone we offer is graded and certified, so you know exactly what you're getting before it's set.
