Always a type IIA

Our gem-quality diamonds are certified Type IIA exquisitely cut diamonds from 0.01ct up to 4ct.
ALTR creates value that enhances the diamond in new ways. Type IIA is the highest certification given to the purest diamonds, and we ensure that all ALTR created Diamonds have them. The impact that we make through larger carats at better value is completely unique to us.
Our master cutters collaborate with our customers insight team of every stage to create exclusive cuts with a strong aesthetic language that add to the diamonds allure.

Born of fire

Born perfect

Our growing process utilizes advanced scientific knowledge and sophisticated technology to recreate conditions similar to nature’s force exerted over a billion years approximately 200 miles underground.
Our proprietary ALTR diamond reactors and processes, built and perfected over 60 years of combined research, use a Type IIA ‘diamonds seeds’ to create real diamonds. This results in a diamond that is exceptionally beautiful and of higher quality.

The highest

ALTR Created Diamonds are graded with the same standards as mined diamonds and carry certifications from Gem Certification and Assurance Lab (GGAL).


Is Created/Lab-grown diamond a new phenomenon?
Diamonds were first created in a lab at General Electric in the 1950’s. However they weren’t gem quality diamonds that could be used in jewelry. The process has been used ever since to produce industrial diamond for abrasives and manufacturing. Over the past few decades, methods have been perfected, but only in the last few years has it been possible to produce large white gem-quality diamonds that meet or surpass natural diamonds in terms of desirability and beauty. So while lab-grown diamonds aren’t a new phenomenon, they have become viable for fine jewelry only recently.
How are ALTR Created Diamonds different from mined diamonds?
ALTR Created Diamonds are man made by simulating natural conditions of extreme heat and pressure or chemical vapor deposition. Both mined and created diamonds are identical in chemical, optical and physical composition.
What is Type IIA?
The most famous and brilliant natural diamonds in the world are IIA!
The Koh-I-Noor, The Elizabeth Taylor Diamond (Krupp), The Regent Diamond and The Star of The South are all famous Type IIA diamonds.
Only the best 1 to 2% of mined diamonds can be called Type IIA. They are the purest and most thermally conductive of all diamonds. As natural diamonds rise toward the surface of the earth from the depths, they are usually deformed or form imperfectly taking on certain impurities. Type IIA stones are almost entirely devoid of these imperfections and deformations. All ALTR created diamonds are Type IIA.
How are ALTR diamonds created?
Our diamonds are created by replicating certain favorable conditions growing crystal carbon. A sliver of an existing Type IIA  diamond, otherwise known as a “seed”, is placed in an environment that contains a specific recipe of carbon compounds. The seed is then subjected to a process called Chemical Vapor Deposition (CVD), wherein the crystals are formed from hot plasma in layers, like semiconductors. What results is a real ALTR Created Rough Diamond with all the natural properties of a mined diamond.
What is the difference between a simulant and an ALTR Created Diamond?
Both, ALTR Created Diamonds and gem quality earth-mined diamonds are composed of incredibly pure crystal carbon as a single crystal. Simulants may look somewhat similar but the material is completely different, with different physical properties. An ALTR Created Diamond’s refraction and hardness is identical to a natural diamond’s, unlike a simulant, which fails to meet the standards. An ALTR Created Diamond is a real diamond unlike diamond-like materials such as cubic zirconium, moissanite and diamond-coated materials, with a wide range of color, clarity, carat and cut possibilities.
If ALTR Created Diamonds are exactly the same as mined diamonds why are they classified separately?
While there is no difference between a mined and ALTR  Created Diamond, our consumer’s ability to make an informed choice must be protected. Complete disclosure is ethical and also in the best interest of the consumer .  
So what happens when an ALTR Created Diamond is put in a diamond tester?
Natural and ALTR Created diamonds are both composed of the same crystal carbon material and exhibit identical properties. The only differences that can be detected are minute differences in the crystal formation and/or different trace impurities. A Diamond tester will positively identify an ALTR Created Diamond as a diamond.
So ALTR focuses on growing diamonds as well as design and marketing of jewelry?
Yes. As a brand that is working towards widening the horizon of the diamond industry as a whole, our aim is to ensure that diamonds increase in value and remain the cherished and precious investment they have always been.

How does ALTR plan to inject fresh thinking in terms of design?
We have enlisted talent from many sources to design our jewelry. This infuses our designs with a fresh approach, a modern outlook and allows us to cater to a wide variety of tastes, instead of merely improving on what is already selling. We are confident that this strategy will result in high quality designs that appeal to the modern customer who is design conscious and earlier considered diamonds to be old-world and traditional.
How much time does it take to create a diamond in the laboratory?
Depending on the color and size, it can take between 60-120 days to create a diamond in the laboratory.
What certification authenticates ALTR Created Diamonds?
ALTR Created Diamonds are graded with the same standards as mined diamonds and carry certifications from Gem Certification and Assurance Lab (GCAL). It is probable that other grading laboratories will certify created diamonds in the near future.
How does an ALTR Created Diamond enhance personalization?
With over 26 exclusive patented cuts, design options to personalize or customize jewelry increase dramatically with ALTR. Our diamonds can be created in a variety of colors, cuts and sizes to fit a specific design or customer need as well.
