If you are serious about locating precious stones underground, Blue Diamond by Next Labs Germany is not just another metal detector; it is a specialised diamond and gemstone detection system built for accuracy and long-range performance.
Designed for both professionals and advanced hobbyists, this powerful gold and diamond detector machine helps you locate white, blue, and pink diamonds as well as valuable gemstones like emerald, sapphire, ruby, garnet, and more.
Whether you are searching remote terrain or mineral-rich soil, this advanced metal detector UK prospectors trust combines simplicity with precision.
Most traditional metal detectors focus only on metals. Blue Diamond is engineered specifically for:
If you’re searching for a professional-grade diamond detector UK treasure hunters prefer, this device delivers structured search programs, adjustable scanning ranges, and guided visual direction technology.
Blue Diamond operates using long-range locating technology with:
The system scans large areas up to 3000 meters front range and detects targets up to 25 meters deep.
Instead of random digging, the device analyses emitted signals and guides you precisely toward the target location.
This makes it a powerful addition for any serious metal detectorist looking to upgrade from a basic metal detector for gold or gemstones.
Blue Diamond includes two dedicated search systems:
Designed specifically for:
Adjustable settings include:
This flexibility makes it ideal for prospectors seeking a focused diamond detector machine rather than a general metal detector.
Search for:
Sapphire, Emerald, Garnet, Amethyst, Lazuli, Tourmaline, Turquoise, Peridot, Alexandrite, Ruby, Jasper, Opal.
Users can customise:
If you’re searching for a gemstone and gold metal detector buyers can rely on, this system provides structured targeting for more refined exploration.
Unlike complex industrial detectors, Blue Diamond features:
It’s designed so both professionals and serious hobbyists can operate it without technical confusion.
If you are planning to buy a metal detector online for gemstone hunting, ease of use matters just as much as depth capability.
Everything you need to start professional gemstone detection immediately.
Blue Diamond is ideal for:
If you’re comparing price vs performance, this device offers targeted gemstone technology rather than generic detection.
£2,150, with a three year warranty, which is longer than most equipment at this level. It is the only dedicated gemstone instrument we stock, so there is no cheaper alternative in this category from us.
Not by metal detection, because stones are not conductive. This instrument responds to a different physical property, which is why it can indicate stones no metal detector would see. The physics is real. How well it translates into finds depends heavily on ground conditions and on the operator.
The diamond system targets white, blue and pink diamond. The gemstone system covers sapphire, emerald, garnet, amethyst, lazuli, tourmaline, turquoise, peridot, alexandrite, ruby, jasper and opal, and you select the specific target type rather than searching blind.
Depth is adjustable from 0 to 25 metres and the front scan range from 0 to 3,000 metres. Being able to set both is the point: you narrow the search to the depth band and distance you actually believe in rather than accepting a fixed setting.
Less than you would expect. A 2.8 inch touch screen, an eight language interface and a visual guidance system with simple menu navigation. The difficulty in this category is interpretation, not operation.
The main device unit, grip, SP signal transmitter, two receiving antennas, a compass, an electrical charger, a car charger and a lithium ion battery. Free worldwide delivery is included.
British geology is not gem bearing in any commercially meaningful way, so honestly there is very little here to find. This is equipment for overseas prospecting on ground already known to carry stones. We would rather say that than sell you one for a UK field.
That is a different measurement and a different instrument. For gold prospecting see our GER and UIG long range systems, and for the wider range of specialist locators the Next Labs page.
