Wholesale Lab Grown Melee Diamonds - Bulk Parcels for Manufacturers
Full sieve size range, consistent quality, direct from our Surat facility since 2018.
Melee Diamonds Introduction
Melee diamonds serve a different purpose than solitaire-grade stock — manufacturers setting a hundred stones into a single pavé band don’t need any one stone to be exceptional; they need the parcel to perform consistently across the finished piece. Mismatched sizing or uneven color can mean additional sorting and production time, which is why parcel uniformity matters so much when sourcing melee.
OCS Diamond stocks melee across the full sieve size range, in both CVD and HPHT, with inventory refreshed every 2 days. Since 2018, we’ve supplied melee to jewelry manufacturers across our 50+ client base in India, the USA, the UK, Europe, the Middle East, and Australia, using the same IGI-backed, internally reviewed quality standard applied across our inventory.
Parcel orders start at a 5 carat minimum. If this is your first order with us, you can request a 1 carat sample — fixed or mixed size — to verify the parcel before committing to bulk, with the same advance-payment or escrow terms as any order.

Understanding Melee Sizing
The trade uses sieve numbers, not just millimeters, to sort small diamonds by size — a physical sieve plate with holes of a specific diameter separates stones into consistent size bands faster and more precisely than measuring each stone individually. In standard Indian trade terminology:
Star
below 1.2mm (sieve -2), sometimes called "diamond dust" - used for the finest pavé and micro-accent work
Melee
1.8mm to 2.7mm (sieve 6.5 to 11), roughly 0.02 to 0.08 carat per stone - the standard range for pavé, halo, and accent settings
11+
2.7mm to 3.7mm (sieve 11 to 16), roughly 0.08 to 0.20 carat per stone - used where a slightly larger accent stone is needed
We stock across all three ranges. If you’re ordering by sieve number rather than mm or carat, our team can convert and confirm availability for your exact specification.
Where Melee Diamonds Are Most Commonly Used
Standard melee (1.8mm-2.7mm) dominates halo and pavé band settings, where dozens to hundreds of stones surround or line a piece. Star size melee is used for the finest detail work — micro-pavé and delicate accent lines where standard melee would look disproportionately large. 11+ size melee bridges the gap between accent stones and a true center stone, often used in three-stone or cluster settings where a slightly larger supporting stone is needed without the cost of a solitaire-grade piece.
What Determines Melee Pricing
Melee pricing works differently than solitaire pricing — you’re buying consistency at volume, not grading any single stone’s exceptional qualities. Price per carat generally increases as sieve size increases (larger melee costs more per carat than star-size), and clarity consistency across a parcel matters more than the ceiling grade of any one stone. A parcel with tight color and clarity matching commands a real premium over a mixed-grade parcel of the same average quality, because matching is exactly what a manufacturer is paying to avoid having to sort themselves.

Frequently Asked Questions
We stock the full range from Star through 11+. Tell us your sieve number, mm size, or carat target and we’ll confirm the current availability for your specification.
Every parcel is internally reviewed by our gemology team for matching before it’s listed — this is specifically what most melee buyers tell us they struggle to find elsewhere.
Yes — tell us your setting type and stone count, and we’ll confirm whether we can match that from current stock or need to build a custom parcel.
A sample is intended for evaluation before a bulk purchase, while a full parcel is the production quantity ordered to your required specification. Samples start at 1 carat, while parcel orders start at 5 carats.
This depends on the order — smaller melee is typically certified at the parcel level, while larger 11+ size stones can be individually certified on request. Confirm your requirement with our team before ordering.
