White Label and OEM Lab-Grown Diamond Jewelry from Istanbul: IGI-Certified Wholesale Guide
Lab-grown diamonds have moved from a niche to a regular part of fine jewellery collections, especially in engagement rings and tennis bracelets. Brands and jewelers who want to serve this demand need a manufacturer that can produce reliably. This guide explains how white label and OEM production works with OSKA in Istanbul.
White label, private label and OEM: what is the difference?
- White label: you choose existing, already-tooled models from our collection and sell them under your brand. This is the fastest start.
- Private label: a series made for your brand with your choices of karat, colour, stone and finish.
- OEM or custom: your own design or CAD file is developed, sampled and produced. The design is never made for anyone else.
What sells right now
Yellow and white gold are both widely chosen for lab-grown engagement rings, and round and oval are among the most requested shapes. Centre stones tend to be larger with lab-grown diamonds, since the same budget goes further. For fine jewellery, 14k is widely requested in the US, with 10k for entry ranges and 18k popular in Europe. 925 silver with rhodium suits fashion collections.
IGI-certified lab-grown diamonds
For centre stones we supply IGI-graded lab-grown diamonds and can work with stones you supply. Always match the report number to the stone. Small accent stones in tennis bracelets and pavé pieces are matched by size, colour and clarity.
How an order works
- Send your model, metal, karat, stone and quantity for a quotation.
- A paid sample (one piece per model) is made. Its cost is deducted if the sample becomes an order. For new models, the mould fee is also deducted from the order.
- Production minimum: at least 1 kg per production order; the number of pieces depends on the weight of each model.
- Payment terms: deposit, with the balance at delivery.
- Orders ship worldwide with insurance. Every piece carries a hallmark.
- Your logo can be applied on the piece.
Why Istanbul?
Our workshop is in the Grand Bazaar area, with CAD design, casting, stone setting, plating and finishing under one roof, so sample changes are quick and communication is direct. We are an ITO-registered manufacturer.
