Diamond slices are one of the most exciting wholesale categories in the USA jewelry market right now — and one of the most misunderstood. Not faceted. Not rough. Not polished in the traditional sense. Diamond slices are thin, flat sections of natural diamond crystal, laser-cut or naturally cleaved, that reveal the internal character of the stone in a way no other diamond cut can. Included, translucent, opaque, geometric — every slice is genuinely one of a kind.
What started as a niche material for avant-garde designers has quietly become a mainstream wholesale category. USA jewelry designers, independent retailers, and custom jewelers are using diamond slices across a wider range of applications than ever before — from floating pendants and statement rings to personalized laser-cut monograms and rare collector pieces. This guide covers seven of the most commercially significant ways diamond slices are being used in USA fine jewelry right now, with direct sourcing links to GDBS's raw diamond and slices collection for each application.
What Are Diamond Slices? A Quick Sourcing Primer
Before diving into design applications, it helps to understand the product categories within the diamond slice and raw diamond wholesale spectrum. GDBS's Raw Diamond & Slices collection covers several distinct types:
• Natural flat diamond slices: Thin, flat sections of natural rough diamond crystal — white, grey, black, or multicolor. Freeform shapes or approximately geometric. The signature product of the floating diamond jewelry movement.
• Laser-cut diamond slices: Flat diamond material precision-cut into specific shapes: hexagons, shields, triangles, stars, flowers, hands, lock-and-key forms, and custom monogram initials. A completely different product from freeform slices — consistent shape, calibrated sizes.
• Polished diamond slices (polkis): Traditional Indian polki diamonds — flat, naturally shaped diamonds with a polished front face. White, salt & pepper, black, and brown. The foundation of polki jewelry, now a growing USA retail category.
• Raw rough uncut diamonds: Unprocessed natural diamond crystals — octahedrons, rough chunks, crystal forms — used as statement focal stones in raw diamond jewelry.
• Coin and freeform large diamond slices: Large-format flat rough diamonds in coin or organic shapes — rare statement pieces for one-of-a-kind commissions and collector jewelry.
GDBS supplies all five types across a comprehensive range of colors, sizes, and quantities — giving USA wholesale buyers access to the full raw and slice diamond spectrum from one direct manufacturer source.
1. Floating Diamond Slice Pendants — The Category That Started It All
The floating diamond pendant — a thin diamond slice suspended in a bezel, on a fine chain, or simply drilled and hung directly — is the design application that first brought diamond slices into mainstream USA retail. The appeal is the transparency: a diamond slice pendant catches light differently from every angle, and the included internal patterns visible through the stone give each piece a completely individual character.
GDBS supplies the core wholesale materials for this application. The 5ct parcel of 2mm–4.5mm clear white natural diamond slices — flat, laser-cut for easy setting — is one of the most practical wholesale buys in this category. The 5ct parcel of 2mm–4mm sparkling clear white natural diamond slices gives designers the clarity and translucency that makes floating pendants so visually distinctive.
For statement floating pieces, the white raw diamond drop pendant — laser-cut, chain-it-and-wear-it ready — is a finished retail-ready pendant component, not just a loose stone. The 23x13mm purple-green diamond slice drop with 22kt gold filled connector represents the premium end of this category — a rare color combination in an unusually large format.
2. Laser-Cut Geometric Diamond Slices — Precision Shapes for Modern Fine Jewelry
One of the most significant developments in the diamond slice category over the past three years is the rise of laser-cut geometric diamond slices — flat diamond material precisely cut into consistent geometric shapes. Where freeform slices are each unique, laser-cut shapes offer calibrated consistency for production jewelry while retaining the raw, natural diamond aesthetic that makes this category compelling.
GDBS offers an exceptional range of laser-cut geometric diamond slice shapes for USA wholesale buyers:
Hexagon laser-cut diamond slices: Calibrated hexagon black diamond cabochons in 3mm, 4mm, and 7mm — a bold geometric shape surging in popularity for men's rings, unisex fine jewelry, and architectural design aesthetics.
Shield-hexagon laser-cut diamonds: Shield and hexagon combined shape in 3x2mm, 4x3mm, and 7x6mm calibrated sizes — a distinctive hybrid shape that works in both ring and pendant applications.
Triangle laser-cut diamond slices: 10-piece sets of white and yellow polished triangle diamond slices (4.5mm–8mm) and a 30-piece parcel of 5mm–6mm grey triangle diamond slices (5ctw) — both ideal for production earring and pendant programs.
Flower-shaped laser-cut diamonds: White and black flower-shaped loose diamonds in 5mm and 7mm — a nature-inspired shape with strong appeal in the bohemian and artisan jewelry segments of the USA market.
3. Personalized Laser-Cut Monogram Diamonds — The Fastest-Growing Segment
If there is one segment of the diamond slice category that has genuinely surprised USA retailers in recent years, it is personalized laser-cut diamond monograms. The ability to cut a natural rough diamond into a specific initial, letter, or custom shape — and sell it as a named, personalized piece — has created an entirely new product category at the intersection of fine jewelry and the gifting market.
This is not a gimmick. A customer buying a diamond initial pendant is buying a real natural diamond, laser-cut to their specific initial, delivered as a piece of genuine fine jewelry. The personalization adds perceived value that justifies a retail premium — and the repeat purchase rate for initial necklaces in the USA gifting market is among the highest in fine jewelry.
GDBS offers this wholesale: 4mm monogram initial personalized laser-cut diamond for name necklace applications, and a larger 5mm raw diamond monogram laser-cut stone for retailers who want a more visible initial. For production retailers running initial necklace programs, raw diamond matched pairs in monogram initials allow earring pairs to be produced — both initials matching in size, cut, and character.
4. Statement Laser-Cut Diamond Shapes — Hands, Stars, Lock & Key
Beyond geometric and monogram forms, GDBS produces a category of statement laser-cut diamond shapes that have no equivalent in traditional fine jewelry supply: hand-shaped diamonds, star diamonds, lock-and-key diamond pairs, and coin diamonds. These are collector and occasion pieces — high-value, highly individual, suited to gallery retailers, high-end custom jewelers, and designers building editorial collections.
The rare 17.10ct hand-shaped laser-cut black polished diamond (28x14mm) is a genuinely rare statement piece — a hand-shaped natural diamond at a scale that commands attention as a pendant centerpiece. The star diamond 3-piece set (8mm stars + 10mm focal pendant) provides a matched pair plus centerpiece for a layered necklace program.
The lock and key laser-cut raw diamond set is purpose-built for the couples jewelry and gifting market — a lock-and-key pair in natural diamond for pendant or ring applications. A product with built-in storytelling that USA retailers can sell immediately without explanation.
5. Polki Diamond Slices — The Traditional Indian Cut Taking USA Retail by Storm
Polki diamonds — flat, naturally shaped diamonds with a polished front face, used in traditional Indian jewelry for centuries — have found a new and enthusiastic audience in the USA fine jewelry market. The appeal is the combination of an organic, uncut-feeling aesthetic with a polished, refined surface: the stone looks raw and natural but has a defined luminosity that faceted rough diamonds lack.
GDBS supplies polki-style diamond slices across multiple color options. The 10-piece parcel of 3mm–5mm white, salt & pepper, black, and brown natural diamond polished slices covers all four of the main color profiles USA retailers are currently selling in this style. The mixed-color parcel format means a single wholesale order gives retailers variety across one product line.
Polki-style slices work particularly well in yellow and rose gold settings, where the warm metal and the organic diamond aesthetic complement each other. USA retailers serving the boho fine jewelry, global-inspired jewelry, and artisan bridal markets should have polki diamonds in their wholesale inventory.
6. Fancy Color Raw Diamonds & Slices — Black, Blue, Champagne, and Two-Tone
The raw and rough diamond slice category is where natural fancy color diamonds become accessible to a wide range of USA retailers — including those who could never justify the cost of faceted fancy color diamonds. Raw rough diamonds in black, blue, champagne-brown, cognac, grey, and two-tone natural combinations are wholesale-priced at a fraction of what equivalent faceted color diamonds cost, while delivering visual impact that often exceeds their price point.
Black raw rough diamonds: 2-piece and 10-piece sets of 4mm heated black natural rough round diamonds easy-to-set, 5mm black rough raw uncut loose diamond wholesale lots, and large 10mm black heated uncut loose diamond with 1mm drill for statement pendant applications.
Blue raw diamonds: 4mm–5mm rare raw blue diamond smooth crystal, 6mm–7mm blue raw diamond octahedron drilled irradiated, and 4mm natural blue rough flat diamonds irradiated easy-to-set (2 & 10-piece) — blue raw diamonds for pendant and ring applications.
Champagne and cognac brown: 5mm cognac champagne brown smooth natural raw diamond and 4-piece champagne brown cognac octahedron crystal parcels (2.5mm–4mm) — natural octahedron crystals in warm tones that pair perfectly with rose gold settings.
Two-tone and multicolor: 5-piece parcel of 6.5mm–8.5mm rare two-tone grey-black raw rough diamonds (5.92ctw) — each stone shows dual color zones, a genuinely rare natural occurrence.
Mixed wholesale lots: 10-piece wholesale raw natural uncut loose diamonds in white, yellow, grey, and red (3.5mm–5.7mm) and 10-piece multicolored rough diamond wholesale lots (5mm each) give retailers a color variety assortment in a single wholesale order.
7. Large-Format Coin & Freeform Diamond Slices — Rare Collector Pieces for Gallery Retailers
At the premium end of the raw diamond slice category sit large-format flat rough diamonds — coin-shaped, freeform, and organically shaped — that function as genuine collector pieces and gallery-grade statement jewelry focal stones. These are not production items. Each is unique, priced individually, and suited to high-end custom jewelers and gallery retailers serving design-aware, premium buyers.
GDBS's collector-grade diamond slice inventory includes: OOAK 9.25ct–13.40ct grey flat raw rough coin-shaped loose diamonds (16mm–21mm) — flat, coin-shaped, high-lustre grey diamonds at a scale rarely seen in wholesale supply. Each piece is genuinely one-of-a-kind.
The OOAK 20.02ct–13.70ct natural black-grey high-lustre rough mined diamonds (22mm–19.7mm) push into territory normally reserved for auction houses — 20ct+ natural rough diamonds with high surface lustre for the serious collector market.
More accessible but still statement-grade: white triangular freeform raw diamond slices (4mm–8mm) and black freeform triangular flat diamond slices (4mm–8mm) — organic, individually unique stones for custom ring, pendant, and brooch work.
The 9-piece parcel of 9mm–17mm smooth grey-yellow rough unique uncut flat diamonds rounds out the large-format category for designers who want a curated selection of individually unique statement stones in one wholesale order.

Frequently Asked Questions
Q: What is the difference between a diamond slice and a rough diamond?
A diamond slice is a thin, flat section of natural diamond — either naturally cleaved or laser-cut from a rough diamond crystal. It is flat, with a large table surface that reveals the internal character of the stone. A rough diamond is an uncut natural crystal in its three-dimensional form — octahedron, cube, or irregular chunk. Both are natural, unpolished in the traditional sense, but they look and function differently in jewelry settings. Diamond slices are used for floating pendants and flat-set applications; rough diamonds are used as raw focal stones in bezel and prong settings.
Q: Are laser-cut diamond slices real natural diamonds?
Yes, completely. Laser-cut diamond slices start as natural rough diamond material — the same carbon crystal as any mined diamond. The laser cutting process simply shapes the flat diamond material into a consistent geometric form (hexagon, shield, star, hand, monogram initial, etc.) without adding any synthetic material or treatment. Laser cutting is a precision manufacturing technique applied to genuine natural rough diamonds.
Q: Can I order custom laser-cut diamond shapes from GDBS?
Yes. GDBS produces custom laser-cut diamond shapes for USA wholesale buyers — custom initials, bespoke geometric forms, matched pairs, and production parcels in calibrated sizes. Custom laser-cut diamond orders are one of GDBS's specialties and a key differentiator from commodity diamond slice suppliers. Contact the GDBS wholesale team with your shape specifications and quantities for a custom quote.
Q: What settings work best for diamond slices?
Flat-bottomed laser-cut diamond slices work best in bezel settings (a metal rim that wraps the edge of the stone), which accommodate the flat profile and protect the edges. Drilled diamond slices can be hung directly on chain or wire without a traditional setting. Large freeform coin diamond slices are often set in open-back bezels to allow light penetration from both sides. For rough three-dimensional diamond crystals, bezel, prong, and burnish settings all work depending on the crystal's natural form.
Q: Does GDBS ship raw diamonds and diamond slices to all US states?
Yes. GDBS ships fully insured, tracked wholesale orders of raw diamonds and diamond slices to retailers across all 50 US states. All export documentation, customs compliance, and international shipping logistics are handled by GDBS from its Surat facility — the wholesale buying process is completely seamless for USA-based retailers regardless of order size.
