Choosing Your Pearl Jewellery
Like any gem, pearls vary in shape and colour. At 77 Diamonds, we offer a selection of bright white pearls in round and teardrop shapes. Each gem is meticulously checked to reflect superior quality based on a combination of factors.
A pearl’s size, measured in millimetres, may affect its overall price. Usually, the larger the pearl, the rarer and more costly it is. However, certain small pearls may be more expensive depending on other quality factors.
Pearls are organically created and can therefore vary in shape. Certain designers do prefer irregular shapes for a more contemporary take on pearl jewellery, however, it is widely accepted that pearls should be perfectly symmetrical.
Lustre is probably the most crucial factor affecting a pearl’s quality, as it measures overall visual appearance. Lustre indicates how well a pearl’s surface reflects light, the sharpness of its reflections, as well as its capacity to radiate an inner glow. Superior pearls display a mesmerising lustre that catches the eye, while inferior pearls present a somewhat dull and blurred appearance.
This factor relates to a pearl’s dominant colour, subtle overtones, as well as any intricate hues displayed on its surface. These combined qualities create a hypnotic play of colour that glides gracefully over a pearl, bringing depth and a distinct glow to your jewellery.
When a pearl forms inside an oyster or mussel, it can sometimes be damaged by several factors and affect its surface quality. The most sought-after pearls have little to no surface blemishes, making them extremely rare and expensive.
Depending on their grading quality, certain pearls may hold very slight abrasions or blemishes that are difficult to see. At 77 Diamonds, we only provide pearls that present very few blemishes, practically invisible to the untrained eye.
Nacre is the substance formed by an oyster or mussel to create a pearl. As nacre progressively deposits itself in layers around the seed irritant, it forms a distinct glow. Nacre and lustre generally go hand in hand –- a thick nacre usually indicates superior lustre and finish.
Pearl jewellery often features multiple pearl pieces either placed in a gradient, or similar in size. A jewel’s quality is determined by how well the pearls resemble each other, especially in earrings or necklaces. At 77 Diamonds, we individually select each pearl to achieve a near perfect matching quality.
