We employ best specialist diamond setters available & the give them additional trading so that our setting is world class. A diamond setter (often referred to as a setter) requires a separate apprenticeship to a jewellery apprenticeship because there is considerable expertise required for each. For the long-term security setting of a diamond or gem stone the diamond setter & jeweller must work together. Because we employ both setters & jewellers who work in unison, should a stone fall out of one of our custom made pieces, we will replace it as long as you have been coming in for your yearly checks. This is part of our unique Lifetime Workmanship Guarantee to see it in writing go to Guarantees.
