Different sources use different names to refer to lab-grown diamonds. For example, you might see lab-created diamonds, cultured diamonds, engineered diamonds, synthetic diamonds and even man-made diamonds. The term ‘simulated’ diamonds, does not refer to lab-grown diamonds. Simulated diamonds may look similar at a glance, but do not share the same physical, chemical, or optical characteristics. They are not as hard, and do not have the same sparkle.

Lab-grown diamonds will not appreciate in value like some natural diamonds. The cost of new stones is based on the manufacturing and settings costs, plus a brands individual added margin. The resale value is based on the cost of buying a new stone, rather than any inherent value or rarity as with natural stones.

This depends on the price you pay for a lab-grown diamond originally. As a relatively new manufacturing process, it’s reasonable to expect the cost of production to fall, and lab-grown diamonds purchased at too high of a price will lose value as similar stones will become available for a lower cost. Through our world-leading technology, we’ve already achieved a sustainable pricing model that means our stones are priced transparently at Tk‌73,200 a carat.

Lab-grown diamonds are now widely available online through both lab-grown diamond jewellery brands and through more traditional diamond sellers too. Hamlingtons has a wide range of Lab diamonds in store for you to see.

Natural diamond prices go up exponentially when a larger weight is combined with high quality cut, color and clarity, as this increases a stones rarity. There is no rarity in lab-grown diamonds as more can always be manufactured to meet demand, meaning we can price our stones in a more affordable way.

Lab-grown diamonds have the same physical properties as natural stones, so will be categorized as ‘diamond’ when using a diamond tester pen. This relies on the accuracy of the equipment used, and it being used correctly. Lower price mass-market testers from Amazon can often produce false negatives, so it’s best to consult with a specialist. Specialist equipment that goes beyond a diamond testing pen can always correctly identify the difference between a lab-grown diamond and a natural stone.

Only a specialist with the right equipment can tell the difference between a lab-grown diamond and a natural stone. All certified stones above 0.2 of a carat also have a laser inscription within them (invisible to the naked eye) as a marker of their authenticity and quality.

Lab-grown diamonds make the incredible sparkle of a diamond available to more people, more often. They’re perfect to wear every day or to buy as a birthday or anniversary gift, and because they are manufactured to a consistent high quality you can be confident about buying them online.
