How to Choose a Loose Diamond Trader in Asia

Round brilliant diamond — check calibration before you choose a trader

Asia has no shortage of people who will say they trade diamonds. The useful question is whether they can repeat a calibrated, certified parcel for Hong Kong, China or Bangkok without rewriting the spec after you have booked the setter.

Use this checklist. It is how we would want a factory to judge Tanush Creations — and how we judge ourselves.

1. Can they name the shapes they actually hold?

A trader who stocks everything stocks leftovers. Ask for the cut list. Ours is five: Round, Baguette, Taper, Marquise, Pear. If you need something else, a straight “no” is more valuable than a maybe.

2. Is every stone certified?

Trade buyers do not buy stories. They buy stones that match a certificate and a millimetre list. Uncertified filler slows customs and disputes. We work 100% certified stock.

3. Do they quote millimetres or only carats?

Channel and pavé programmes fail on width, not on a total carat number. A serious trader asks for millimetres first. Carat is a consequence.

4. Is the address real, and is it the only one?

Name, address and phone should match across the site, invoices and maps. Fake “offices” in three countries are a ranking trick, not a supply chain. We have one office: Tsim Sha Tsui. We export to Shenzhen, Guangzhou and Bangkok from there.

5. Will they say no?

If a trader never refuses a spec, they are padding parcels. We source when the shelf is short. We do not invent availability.

6. Can you WhatsApp a spec and get a trade answer?

+852 5444 0834. Shape, size, colour, clarity, quantity. If the reply is a catalogue PDF and no millimetres, keep looking.

Frequently asked questions

What should I ask a loose diamond trader before the first order?
Shapes in stock, certification, millimetre calibration, office address, and whether they export to your factory city. Tanush Creations answers those from Tsim Sha Tsui.
Should I buy from a trader with shops in HK and Bangkok?
Only if both addresses are real operating counters. Many sites list cities they do not occupy. We list Hong Kong only, and export to Bangkok.

Need a certified parcel?

Send shape, size and quantity on WhatsApp. We reply from Tsim Sha Tsui — a Hong Kong loose diamond trader for HK, China and Bangkok (BK) trade buyers.
