What Are Loose Diamonds?
Loose diamonds are individually graded, certified, and sold stones — each one a complete product in itself, accompanied by its own IGI grading report. Unlike melee parcels or accent stone batches where diamonds are sold by the lot, loose diamonds are selected one at a time for specific jewelry pieces: an engagement ring center stone, a solitaire pendant, a pair of matched stud earrings. For B2B buyers, loose diamonds represent the highest per-unit value and the closest relationship to the end consumer's purchase decision.
Loose vs. Parcel: Understanding the Buying Model
The distinction between loose and parcel buying is fundamental to B2B diamond procurement. Parcel buying (melee, accent stones) prioritizes batch consistency — you're buying a group of stones that must match each other. Loose buying prioritizes individual stone quality — you're selecting a specific diamond for a specific purpose, and each stone stands alone on its merits. Loose diamonds are heavier (1ct+ typically), come with individual IGI certificates, and are priced per stone rather than per carat. Yuda Crystal's loose diamond service offers the flexibility to select exact carat weights, colors, clarities, and shapes tailored to your customers' requirements.

How to Order Loose Diamonds
Ordering loose diamonds from Yuda Crystal follows a straightforward process designed for B2B buyers: (1) Specify your requirements — carat weight range, color grade, clarity grade, cut quality, and preferred shape(s). For matched pairs (e.g., stud earrings), indicate that you need two diamonds with matching specifications. (2) Receive availability report — we respond with current inventory matching your criteria, including IGI certificate numbers, exact carat weights, and per-stone wholesale pricing. (3) Select and confirm — choose your stones from the available options. (4) Payment and shipping — standard payment terms apply; shipping via FedEx/DHL/UPS with full insurance (7-14 business days). For first-time buyers, we recommend starting with a small order (1-3 stones) to experience our quality and service before placing larger loose diamond orders.
Matched Pairs for Earrings
Loose diamonds ordered as matched pairs for stud earrings require additional quality criteria beyond individual grading: the two stones must match not just on paper (same IGI grade) but visually — identical face-up size, matching color tone, and compatible brilliance pattern. Yuda Crystal's matched pair service includes visual inspection by a senior gemologist to confirm the two diamonds present as a true pair before shipping. Matched pair premiums typically add 5-10% to the per-stone price, reflecting the additional selection and verification work involved.
