IOBI Cultured Diamond

What is an IOBI Cultured Diamond?


Is a new and exciting way to buy a diamond. IOBI Cultured Diamonds have almost the same physical and visual properties of a naturally formed diamond. Created from a small particle of carbon, it emerges as a rough stone exactly as if created by nature and is nearly impossible to distinguish from a natural diamond. 

 IOBI Cultured Diamonds are cut and polished exactly as a natural diamond to achieve maximum brilliance and be nearly flawless. The highest clarity, color and fire can only be attained by precision finishing processes, resulting in better clarity grading than naturally formed diamonds. 


Created in a controlled environment, IOBI Cultured Diamonds are eco-friendly and require no mining, little energy to produce and are 100% conflict free. At a fraction of the cost, an IOBI Cultured Diamond allows for the purchase of a larger, more elaborate and much more brilliant jewelry piece.

Ring Sizing Chart
Ring sizes listed are in US sizing standards. If you do not know your ring size we suggest the following: 1 - Get a non-stretchy string or paper about 6" long and 1/4" wide. 2 - Wrap around the base of your finger. It has to fit snug, but not too tight, it needs to be comfortable to wear. 3 - Mark the point on the string/paper where it overlaps forming a circle. 4 - Lay the paper/string out on a ruler to determine the measurement. Ring finger measuring tips: Make sure your finger is at a normal body temperature as fingers can shrink or expand when cold or hot. If your knuckle is much larger than your finger’s base, take two separate measurements and choose a size in between. You want a ring to fit over your knuckle, but not be too loose or it will shift around. If you know your ring size in international standards we can convert to US standard using the conversion chart found here We can compare your measurements to the actual ring to ensure fit.
