The Tang&Co. Guide
How to Choose Your Lab-Grown Diamond Engagement Ring
Every Tang&Co. engagement ring is crafted to order in solid 14k or 18k gold, in white, yellow or rose gold, and set with a lab-grown diamond center stone of 1.00 ct or more, accompanied by an independent IGI grading report. Lab-grown diamonds share the same chemical, physical and optical properties as mined diamonds. Learn more about our diamonds.
01
Start with the shape
The shape of the center stone sets the character of the ring, from the brilliance of a round to the long, elegant lines of an oval or emerald cut.
02
Choose the setting
A solitaire lets the center stone speak for itself. A hidden halo adds a band of diamonds beneath it, visible from the side, while pavé, halo, side stone and three-stone designs bring added brilliance.
