ALTR Created Diamonds is a New York-based lab-grown diamond brand and vertically integrated diamond house operated by R.A. Riam Group.
Last updated August 31, 2026
Overview
ALTR Created Diamonds is a lab-grown diamond brand created by R.A. Riam Group, a New York City wholesale jeweler with a multigenerational background in mined diamonds and fine jewelry. The brand was introduced at the JCK Las Vegas trade show in 2016, positioning Riam Group as an early entrant into the emerging consumer and trade market for laboratory-created diamonds. The brand’s development is closely associated with Amish Shah, a member of a diamond-industry family who gained experience in diamond trading and fine jewelry at an early age. Shah joined R & R Grosbard Inc. in New York in 2001 and helped expand that business internationally. After taking over its operations roughly a decade later, he conceived ALTR as a dedicated laboratory-grown diamond business. Under this model, ALTR presents itself as vertically integrated: it grows diamonds, manufactures and cuts them, and develops jewelry using specialist artisans. The company emphasizes Type IIa diamonds, a high-purity category characterized by very low levels of nitrogen and commonly associated with strong optical performance. ALTR’s business covers both loose laboratory-grown diamonds and finished jewelry. Its product and technology story centers on the combination of chemical vapor deposition (CVD) and high-pressure high-temperature (HPHT) methods. In 2018, the company presented a film explaining its diamond-growing process at JCK Las Vegas. ALTR has also publicized a portfolio of patents covering created diamonds and related jewelry designs, although the precise scope and current status of individual patents is not established in the available material. In 2017, ALTR launched LOVEMONSTER, described by the company as the first consumer brand dedicated to lab-grown diamonds. The line used larger-carat Type IIa diamonds and represented an effort to move laboratory-created stones beyond an industrial or trade-only context into branded consumer jewelry. ALTR subsequently promoted unusual and technically ambitious stones, including a 3.99-carat Asscher-cut laboratory-grown pink diamond displayed at Borsheims in 2018. The stone was grown using CVD, graded by GCAL as fancy orangy pink with VS2 clarity, and was presented as the world’s largest lab-grown pink diamond at the time. The brand has also pursued international distribution. Reference material states that ALTR distributes in 20 countries, including markets in North America, Europe, Asia, Australia, the Middle East, and Africa. Its visibility increased when ALTR and president Amish Shah appeared on the premiere episode of CNBC’s Streets of Dreams with Marcus Lemonis, titled “Diamond District,” which aired on December 29, 2020. The program presented Shah and the company as participants in the transformation of the diamond market through laboratory-grown production. ALTR’s public positioning combines traditional diamond-industry expertise with manufacturing control, technological innovation, and an alternative supply model to mined diamonds. Its available history supports describing it as an early branded specialist in laboratory-grown diamonds rather than as a broad luxury conglomerate. Detailed information about current ownership structure, annual sales, present leadership beyond Amish Shah, and the brand’s current retail footprint is not established in the supplied sources.
History
ALTR Created Diamonds emerged from R.A. Riam Group, a New York City wholesale jeweler whose principals came from a family background in the mined-diamond and fine-jewelry trade. Rather than treating laboratory-grown stones as a separate industrial material, Riam Group developed ALTR as a branded diamond business intended to participate in the consumer jewelry market. The brand was publicly introduced at the JCK Las Vegas trade show in 2016. Amish Shah is identified as the founder and the central figure in ALTR’s development. He entered the diamond and jewelry business through his family’s experience and joined R & R Grosbard Inc. in New York in 2001. Reference material credits him with helping turn that company into an international operation. Approximately ten years later, Shah assumed responsibility for its operations and subsequently conceived ALTR Created Diamonds as a specialized laboratory-grown diamond enterprise. The company’s stated model is vertically integrated. ALTR describes its activities as encompassing diamond growth, manufacturing, cutting, jewelry design, and artisan finishing. Its technical narrative focuses on producing high-purity Type IIa diamonds and on combining CVD with HPHT techniques. CVD is used to grow diamond material from a carbon-rich gas, while HPHT applies high pressure and temperature in processes associated with diamond formation and treatment. The supplied material does not establish the exact role of each process in every ALTR stone, but the company has promoted their combined use as part of its production approach. In 2017, ALTR introduced LOVEMONSTER, described as the first consumer brand made exclusively from ALTR Created Diamonds. The launch marked an important shift from selling laboratory-grown stones primarily through trade channels toward creating a recognizable consumer proposition. LOVEMONSTER emphasized larger-carat Type IIa diamonds and gave ALTR a vehicle for presenting laboratory-grown stones as fashion and fine-jewelry products. ALTR continued to use trade shows and demonstrations to explain its technology and distinguish its products. At JCK Las Vegas in 2018, the company unveiled a film about diamond growth, showing the relationship between CVD and HPHT in the creation of its stones. In the same year, it showcased a 3.99-carat Asscher-cut laboratory-grown pink diamond at Borsheims. GCAL graded the stone as fancy orangy pink with VS2 clarity. ALTR promoted it as the largest laboratory-grown pink diamond in the world at that time, making it both a product achievement and a marketing example of the possibilities of laboratory-created colored diamonds. The brand has also claimed a substantial patent portfolio covering created diamonds and distinctive diamond jewelry. The available reference states that ALTR has 49 patents, but it does not provide a patent-by-patent list or clarify how many remain active. The company’s international distribution has been described as reaching 20 countries, with markets cited across the United States, the European Union, Australia, China, Hong Kong, India, Canada, Thailand, South Korea, Israel, South Africa, and Germany. Public attention expanded in 2020 when ALTR and Amish Shah appeared on CNBC’s Streets of Dreams with Marcus Lemonis. The premiere episode, “Diamond District,” aired on December 29 and presented the company within the broader New York diamond trade. The appearance highlighted ALTR’s account of laboratory-grown diamonds as a developing force in the market and portrayed Shah as an early industry participant. ALTR’s historical identity therefore rests on three connected elements: R.A. Riam Group’s established diamond-trade background, Shah’s effort to create a dedicated branded laboratory-grown diamond business, and the company’s attempt to control production from growth through jewelry design. The supplied sources do not provide a reliable founding year beyond the 2016 public launch, nor do they document current financial performance, detailed retail operations, or a complete contemporary executive roster.
