Dops & Accessories

The dop should be chosen based on the size and shape of the stone, so it helps to have a few different sizes and shapes on hand. A handful of small accessories make transfers and alignment far more reliable. Each item below comes in three levels.

Match the dop to the stone

Cone dops

The standard choice for conical or round stones. Metal holds up to the heat and pressure of cutting.

Flat dops

Better suited to tabular or square-cut stones, where a flat bonding surface gives a more stable hold during cutting.

Several sizes

Keep a range of sizes and shapes, so you are never caught without the right dop for an unusually large or small stone. Dop sizes are specific to each machine, so check the quill before you buy.

Dops, wax and transfer

Dops

The stone holders. Choose by the size and shape of the stone, and check that they fit your machine before you buy.

Dop wax and heat

Wax bonds the stone to the dop, and a small, controllable flame softens it. A butane torch is faster, so keep it for transfers once you are comfortable.

Recommended
Transfer jig

Holds both dops in line during a transfer, keeping alignment consistent while the new dop bonds to the stone.

Advanced
Laser alignment system

Confirms a transfer is properly aligned. A laser beam is reflected off one of two opposite facets, and you adjust the handpiece until the beam returns at the same height, then repeat on the opposite facet. Our setup uses a laser and an adjustable mirror holder.

Safety. Use only a low-power Class 2 laser (1 mW or less). Never aim it at your eyes or anyone else’s, and remember that polished facets reflect the beam.

See and measure your work

10x loupe

Lets you inspect each facet up close, which is essential for checking polish and meet points before moving to the next grit. A triplet lens keeps the view sharp and free of color fringes.

Calipers

Used to check girdle diameter and proportions as you cut, and to measure the finished stone against your design. Close the jaws gently, since metal can chip a stone.

Gem tweezers

Choose slide-lock over spring-lock, because a hot stone can pop out of the latter. One good pair is enough at every level.
