Loose Lab Grown Diamonds Wholesale
Wholesale loose lab grown diamonds are unmounted, lab‑created polished diamonds supplied in bulk for commercial jewelry manufacturing and retail. Unlike retail finished jewelry, these loose diamonds are sold as raw lab diamond inventory, available in graded single stones, pre‑sorted bulk lots, and standard melee parcels. This wholesale collection covers full 4C grading ranges, multiple shapes, and consistent batch quality for mass production and custom fine jewelry lines.
Parcels, Matched Pairs, Melee
Our wholesale inventory supports three core bulk formats to fit different jewelry production scenarios: standard melee parcels, precision matched pairs, and pre‑sorted bulk lots. Melee consists of small calibrated stones widely used for pavé setting, side stones, halos, and full band designs. Matched pairs offer identical size, color, and brilliance, perfect for symmetrical earrings, bracelet accents, and twin stone rings.
Pre‑sorted bulk lots provide cost‑effective batch inventory with unified specification ranges, ideal for mid‑range mass production where consistent overall batch quality is required without individual stone certification.
Wholesale lab diamond parcels are bulk packaged stone batches sold by total carat weight, the most popular sourcing format for large‑volume jewelry factories. All parcel stones are pre‑screened for dimension consistency, basic color uniformity, and eye‑clean appearance with strict no‑milk, no‑coffee, and no‑heavy‑fluorescence standards. We offer unified‑size parcels and mixed‑size.
Popular Shapes and Sizes of Loose Lab Diamonds
This collection consists of all popular diamond shapes and commercial sizes for modern fine jewelry production. Available shapes include Round Brilliant, Oval, Pear, Cushion, Emerald, Radiant, Princess, Marquise, and Heart cuts, covering classic and trendy design demands. Size ranges cover full melee from 0.8mm to 3.0mm, small medium stones from 3.0mm to 5.0mm, and large center stones from 0.5ct up to 5ct and above. All calibrated stones feature precise cutting and uniform proportions, ensuring perfect fitting for standard jewelry settings and consistent light performance across finished products.
CVD vs HPHT Diamonds
We supply both CVD and HPHT lab grown diamonds to meet different production and grading requirements. CVD diamonds feature ultra‑high color grades (D‑F), excellent clarity performance, and fewer metallic inclusions, making them the top choice for high‑color luxury center stones and premium retail lines. HPHT diamonds deliver superior crystal density, outstanding fire and brilliance, and stable physical properties, ideal for bright white commercial jewelry and daily wearable pieces. Buyers can select by growth technology based on target product positioning, color requirements, and budget ranges.
