Frequently Asked Questions
ABOUT LAB GROWN DIAMONDS
ABOUT INFINITY STAR
AUTHETICITY
What are lab grown diamonds and how are they different than mined diamonds?
Infinity Star lab grown diamonds are identical to natural diamonds with all the brilliance, fire, sparkle and lasting beauty you love in diamonds. The difference between our lab grown diamonds and mined diamonds is where they form: under the ground of a planet vs in a high - tech laboratory. Even gemologists need special equipment to tell the difference. Infinity Star lab grown diamonds don’t require diamond mining and are always responsibly sourced.
What is the difference between lab grown vs lab created diamonds?
Lab grown and lab - created diamonds are different ways to refer to the same thing: diamonds that are created by growing crystals in the laboratory. The Federal Trade Commission has approved both these ways to refer to lab grown diamonds. We think lab grown is the best way to clearly communicate which are lab grown diamonds and which are natural diamonds so you can choose the ones you prefer.
How do I take care of my lab grown diamond so its sparkle lasts forever?
Because lab grown diamonds are diamonds, they are as enduring as you expect from the world’s hardest gems! They will endure as long as the planet earth. Wipe your Infinity Star engagement ring clean with a soft lint - free cloth. Use a soft brush behind the gem where dust can collect.
How should I choose between the two?
Both are authentic diamonds that look the same. Natural diamonds formed deep within Earth a billion or more years ago and travelled to the planet’s surface in ancient volcanoes. Lab grown diamonds are an innovative new technology to reproduce the conditions in which carbon crystallizes above ground. Both are romantic symbols of a forever love: one about the rarity of a natural treasure, the other about bright and beautiful sparkle that fits in your budget.
What are Infinity Star lab grown diamonds?
Infinity Star lab grown diamonds are cosmic creations born from science and imagination, combining cutting-edge technology with the brilliance of nature’s most legendary gemstone. Just like the fabled Infinity Stones, each Infinity Star diamond is forged using advanced laboratory techniques that recreate the intense heat and pressure found deep within the Earth — the same forces that form natural diamonds. The result? A diamond with the same fire, brilliance, and strength as any mined diamond — but created ethically and sustainably in high-tech labs. Every Infinity Star diamond embodies the power, beauty, and innovation worthy of a hero’s love story, perfect for symbolizing your own epic adventure together.
Where are your Infinity Star lab grown diamonds grown? And how are they being created?
Our Infinity Star lab grown diamonds are created in state-of-the-art laboratories using advanced technology that mimics the natural diamond-growing process. Much like the formation of cosmic gems across the Marvel Universe, our diamonds are born from cutting-edge science, combining heat, pressure, and carbon atoms to form stunning, high-quality stones with the same brilliance, fire, and durability as mined diamonds. We harness Chemical Vapor Deposition (CVD) method, which builds diamonds layer by layer, much like the forging of legendary artifacts. CVD lab grown diamonds are “Type IIa,” which is the purest type of diamond. Less than 2% of natural diamonds are Type IIa. Each Infinity Star diamond undergoes rigorous quality checks to ensure it meets our superpowered standards of beauty and strength, ready to become the center piece of your own epic love story.
What makes the Infinity Star lab grown diamonds collection special?
Every Infinity Star lab grown diamond engagement ring is a tribute to the Marvel stories and characters you love. Each heirloom-quality piece is thoughtfully designed with meaningful details inspired by iconic Marvel moments, symbols, and heroes, making your ring as legendary as your love story. Crafted just for you, your ring is customized with your favorite diamond shape, preferred carat size, and choice of gold color, making it uniquely yours.

Are your lab grown diamonds certified?
Yes! Every Infinity Star lab grown diamond engagement ring comes with an independent grading report from the International Gemological Institute (IGI), one of the most respected gem labs in the world. Just like natural diamonds, our lab grown diamonds are evaluated and certified based on the 4Cs — cut, color, clarity, and carat weight — ensuring full transparency and giving you complete confidence in the quality and beauty of your diamond. This certification is your assurance that your Infinity Star diamond meets the highest standards for brilliance, durability, and craftsmanship, so your ring shines as brightly as your love story.
Because whether born from the earth or created in a lab, a diamond worthy of a hero’s love should always come with proof of its exceptional quality.
