Altr Diamonds
How is ALTR Created Diamond made?
Experience the never before seen journey of a perfect diamond.
Advances in technology mean we now have gem quality lab grown diamonds. Featuring the identical chemical composition and molecular structure of a mined diamond, they really are amazing. They cost approximately 30% less than the equivalent mined diamond which represents a substantial saving. Every stone over 0.50ct comes certified by GCAL, and is laser engraved with it's own unique number. We carry a range of loose stones and ready made jewellery so if we don't have a design in stock that suits you, we can make it.

ALTR - Create Diamonds


1. 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.

2. 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.

3. What is Type IIA?

The most famous and brilliant natural diamonds in the world are IIA!
The Koh-l-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.

4. Are ALTR Created Diamonds available in a variety of sizes?

Yes. Starting from 0.01 ct. to 4 ct., ALTR Created Diamonds can be grown in a variety of sizes. We specialize specifically in large stones that can be a centerpiece for stunning jewelry design.

5. Are ALTR Created Diamonds available in a variety of shapes?

Yes, ALTR produces diamonds in a variety of modern patented and traditional shapes such as round, cushion, princess, ovals, pear, marquise, emerald and more.

6. 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.

7. 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.

8. 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.

9. 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.

10. What are the environmental implications of choosing ALTR?

To find a 1.0 ct rough diamond, approximately 1,750 tons of earth has to be displaced. Since ALTR diamonds are created above earth, we use only a fraction of this energy provided by our own wind turbines leaving a low carbon footprint.

11. How is ALTR distinct from other lab-grown diamonds companies?

ALTR is the only vertically aligned created diamond brand that is a complete and exclusive solution for loose created diamonds and fine jewelry. We have a well appointed dedicated manufacturing infrastructure where we grow our own diamonds. We enhance desirability through our range of created diamonds that qualify as a premium choice for affordable luxury. We start with a diamond seed and finish with hand set fine jewelry because we understand the value that design brings to our pieces.
