High quality at a reasonable price

People often think that working with the best diamond polishers and gold smiths automatically means that we are expensive.

Just ask the hundreds of people who gone before you.

Engraving your jewelry with your name, logo or crest

It surprises us how many of our clients still have their family crest. Sometimes so old that the only thing left is an old-fashioned stamp or even a basic drawing. That´s not a problem at all at Coster Diamonds, since we have so much experience with this type of work that the cost of engraving compared to any diamond ring is extremely affordable.
