Diamond Manufacturing
Where Precision meets Brilliance
Growing the diamond is only the start. Each rough crystal is scanned, mapped, and planned using advanced modeling to determine the desired cut and maximum yield. It then undergoes a water jet guided laser cutting, faceting, and multi-stage polishing to achieve optimal symmetry and fire. Every step, from planning to grading, is governed by ALTR’s calibrated systems for consistent, verifiable quality.
Design & Patents
Creativity drives invention at ALTR, with a portfolio of over 100 diamond cuts, 5 colors in 25 hues, and 49 design patents. Each unique combination of color and cut becomes a mark of distinction, offering our partners both a competitive edge and the ability to express their brand identity through leadership in diamond design.
The art of the facet
Every ALTR Created Diamond is shaped by the hands of skilled artisans, trained in advanced cutting techniques that blend Technology with Human Intuition.
From our signature TYPE Solitaire Initials to playful designs like the Teddy Bear and striking 6-Point Star, ALTR's robotic polishing techniques bring each diamond to a finish that ensures maximum refraction and reflection, benchmarking the standards established for brilliance, sparkle, and scintillation.
Proprietary Calibration ensures every angle is carefully aligned, while technology-guided systems deliver unprecedented Consistency over and over again.
CALIBRATED FOR BRILLIANCE
This engineered uniformity allows every ALTR Created Diamond to integrate seamlessly into fine jewelry collections, delivering quality, structural harmony, and effortless assembly across all designs.
RESPONSIBLE MANUFACTURING
ALTR holds SCS-007 Certification with a perfect 100 Sustainability Rating, ensuring Net-Zero Carbon operations, fair labor practices, safe working conditions, and transparent supply chains.

Frequently Asked Questions
What happens after a diamond is grown?
After an ALTR Created Diamond is fully grown and removed from the growing chamber, it enters the diamond manufacturing stage.
The rough diamond is scanned, mapped, and planned using advanced imaging technology to determine the optimal cut. ALTR experts evaluate clarity, growth patterns, inclusion placement, and yield to guide precision cutting; a journey where pioneering technology meets over 90 years of craftsmanship, transforming raw crystal into an ALTR Created Diamond.
Every finished diamond is then graded, quality-checked, and matched to ALTR’s calibrated diamond standards before distribution.
Does ALTR have any patented diamond cuts?
Yes. ALTR holds more than 49 patented and proprietary diamond cuts, engineered through technology-driven light analysis to maximize brilliance, fire, and symmetry.
These patented cuts provide retailers and manufacturers access to custom-made shapes, strengthening product differentiation and private-label programs.
Does ALTR do custom cuts and diamond designs?
Yes, ALTR redefines diamond design through unconventional shapes, cuts, and colors custom designed for jewelry retail, wholesale, design driven brands.
Our creativity extends beyond classic forms; we develop custom cuts with optimized facet arrangements, proprietary angles, and innovative pavilion designs that maximize reflection and refraction in ALTR Created Diamonds.
Through advanced CVD technology and Calibrated Craftsmanship, ALTR creates diamonds in rare hues such as Burlingame Blue, King’s Green, and Sunset Blush, along with avant-garde shapes like Teddy Bear, 6 Point Star, and Para Oval.
What standards do ALTR Created Diamonds meet?
ALTR maintains the highest standards through a rigorous multi-stage quality control process. Every diamond undergoes crystallographic analysis and inclusion mapping after the growing process, dimensional verification and facet angle measurement during cutting. Our vertically integrated model ensures full traceability and accountability from creation to completion.
Each stone can be graded by GCAL (Gem Certification and Assurance Lab), validating it on numerous characteristics of a diamond, including the 4Cs (Cut, Clarity, Color & Carat), photomicrographs, optical brilliance, fire, scintillation, symmetry, and hearts & arrows confirming adherence to ALTR's benchmarks.
How does ALTR maintain consistently Calibrated Craftsmanship with scaled production?
ALTR maintains calibration through laser mapping, precision cutting tolerances, technology driven proportion measurement, and batch-by-batch QC checks.
We ensure uniformity across stones, from a 0.08mm pavé or a 40-carat solitaire, using standardized proportion and tolerance frameworks, essential for manufacturers, multi-diamond layouts, and calibrated diamond lines.
While technology sets the foundation for precision, our team stays actively involved, personally guiding each project, monitoring progress, and upholding Consistency across every interaction.
What goes into ALTR’s lab grown diamond manufacturing process?
As a leader in lab-grown diamond innovation, ALTR’s lab-grown diamond manufacturing process combines computerized planning, laser cutting, hand finishing, and multi-stage polishing to ensure every stone meets strict calibration, color consistency, and precision-cutting standards required by jewelry retail, wholesale, and design-driven brands.
Our experts integrate CNC-guided technology with master craftsmanship to maintain uniformity across batches, a critical requirement for B2B diamond supply and multi-diamond matching.
Each finished diamond is evaluated for cut accuracy, symmetry, and SCS-007–aligned quality benchmarks, fully aligning with ALTR’s proprietary 5Cs
Are ALTR Created Diamonds certified?
Yes. Every ALTR Created Diamond is certified by leading international gemological laboratories such as GCAL, GIA, and IGI using the traditional 4Cs framework.
Beyond standard certification, ALTR applies batch-level calibration, SCS-007 sustainability compliance, and internal quality audits to ensure the consistency required for wholesale orders, multi-diamond layouts, and high-volume manufacturing partners.
This provides jewelry buyers with traceable, certified, and responsibly produced lab-grown diamonds.
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, oval, pear, marquise, and emerald.
Our 5C driven methodology ensures shape-to-shape calibration, enabling retailers and designers to maintain consistency across collections.
Do ALTR Created Diamonds have unique inscriptions for easy identification?
Yes, each ALTR Created Diamond over 0.70 ct has a unique ID inscribed on the diamond itself. This information is detailed in your certificate, so you can always identify your diamond with the help of a jeweler.
In what ways are ALTR’s 5Cs applied throughout diamond manufacturing?
The 5Cs of ALTR: Creativity, Consistency, Calibration, Craftsmanship, and Compliance, guide every stage of diamond creation. Creativity inspires pioneering cuts, colors, and designs. Consistency ensures uniformity in size, purity, and finish across every stone. Calibration governs precision not just in production, but in the care and reliability we deliver to our clients. Craftsmanship transforms each diamond through meticulous planning, cutting, and polishing by our artisans. Compliance guarantees full traceability, independent certification, and adherence to environmental and sustainability standards. Together, the 5Cs ensure that every ALTR diamond reflects ideation, innovation, and integrity.
