Solico provides the best polish value plan and it saves marking system. Solico is going to re-format on all diamond manufacturing. For example, why do you need to mark a crystal stone and give it to sawing. which might divide it (not as marked) to two non-identical pieces by mistake? With Solico, you can saw it immediately where you planned. Solico saves processing on the diamond such as: marking, shape cutting, table polishing, pavilion pre-blocking and crown pre-blocking.
