Small calibrated natural diamonds
When purchasing small diamonds, it is essential to rely on a truly dependable supplier who not only delivers properly assorted diamonds but also thoroughly verifies their natural origin.
Small natural diamonds
Your setter will be delighted with our small diamonds. No more complications from incorrectly provided dimensions, leaving you with more time to focus on your clients.
You can order 1 or 1,000 pieces, and your order will always be prepared with the same precision.
Sifting is just the beginning
We have dedicated sieve sets for natural diamonds, which are never used for sifting lab-grown diamonds.
However, that is only the beginning; everything must then be checked.
Precise calibration
It’s not just about correctly sifting through small diamonds; it’s also essential to verify that the dimensions requested by the client are indeed accurate. We use many precise calipers, regularly checking their accuracy against certified reference standards. This allows us to quickly determine if the calipers we use need to be recalibrated, replaced, or decommissioned.
We take precision very seriously. The verified calipers we use are also available at:
Individually graded diamonds over 3.30 mm
We have individually appraised diamonds over 3.30 mm / 0.14 ct, precisely measured them, and determined the color and clarity for each stone.
In the individually graded diamonds section, you will find everything ranging from 3.30 mm to 4.15 mm.
Order Preparation
If you place your order by 12:00 PM on a business day and the ordered diamonds are in stock, we will ship them the same day.
Large orders are not a problem
Do you regularly place orders for small diamonds? We would be pleased to meet with you, determine your needs, and propose a tailored solution.
Schedule an in-person or virtual meeting with us.
We check every diamond, even the smallest one, for its natural origin.
We go into great depth. We deal with the gemological aspects of diamonds at an expert level, which we then use when inspecting deliveries of small diamonds from cutting facilities. We use a combination of inspection methods that all natural diamonds go through without exception before we stock them. Below you can see some footage from parts of the inspection process.
