What to Include in Your Inquiry
The more precisely you describe what you need, the faster we can quote accurately — and the fewer emails it takes to reach a price. Include the following and we can usually send availability and pricing in a single reply.
Your Company & Market
Your company name, your country, and whether you buy as a jewelry retailer, a diamond wholesaler, a manufacturer, or a brand.
Product Specification
Shape, size range (mm or carat), color, clarity and quantity — or simply attach your own specification sheet and we will work from that.
Volume & Timeline
Whether this is a trial order or recurring supply, your target price if you have one, and when you need the stones delivered.
What Happens After You Send Your Inquiry
We usually reply within one business day with availability, IGI certification details and wholesale pricing. If something in your specification is unclear we ask a specific question rather than send a generic quote, so the first reply is usually one you can act on. If your requirement is urgent, WhatsApp is the fastest route.
Not sure about all of it? Send what you have — a photo of a similar stone or your last purchase order works too. We will help you narrow the specification.
