Mariko Tsuchiyama Product Information

1. Pearls
Four important elements for grading pearls:

1. Size
The size range of pearl is different by each type of clams. The value is graded by the shape, color, and lustre, and size. Today, a numbers of pearl farms are closed, and Akoya pearls are affected by the severe sea environment. Last year many Akoya oysters couldn’t survive in the sea (the reason hasn’t been stated, but it’s regarded as the situation of the sea and the clam’s genetic problem), so pearls are getting more precious and precious.

2. Shape
In general, round pearls used to be popular as fine jewelry, but we love using irregularly shaped baroque pearls because they have unique characters.
The dimples, circles, and irregular shapes created during the process of pearl production are one of the attractions of natural pearls. The dents on the surface that are called ‘dimples’ are proof of the real thing made by nature.

3. Colour
Pink, white, blue, yellow, grey (Akoya pearls)
Black, peacock green, red (Tahitian pearls)
Honey, amber, white, yellow (South sea pearls)

We often use “Natural blue pearls’ which haven’t been touched artificially also rare and valuable. The color is not artificially changed), the beauty of the material is utilized, and each one has individuality. Complex-colored pearls are rated highly valuable.

4. Lustre
The lustre of the pearl surface caused by the irregular reflection of the layers in the pearl. The greater the number of pearl layers, the stronger the shine and lustrous. The more pearl layers, the more pearls are beautiful and shines. Akoya and South Sea pearls generally have many layers and they are beautifully illuminated.

Akoya pearls
Pearls from Akoya oysters. Mainly cultivated in Nagasaki, Mie, Ehime and Kumamoto in Japan. The sea with clean and calm currents is suitable for aquaculture. Since ancient times, Japanese Akoya pearls have gained high praise are very expensive. (Kojiki, Greek mythology, Cleopatra melting pearls and drinking).
Before the development of aquaculture techniques as they are now, they were harvested by divers. Most are 4mm to 7,5mm, and over 8mm pearls are very valuable. We often uses rare pearls of 8mm or more. We often use pearls from Kyushu where the designers is from. It takes over 4 years to grow Akoya pearls. Pearl farmers check the quality of water and the condition of the oysters every day, and always make sure whether the oysters are living comfortably. Cultured Akoya oysters have a 50% chance of surviving to the end, and less than half of surviving being sold as fine white/round pearls. We use one of the most unusual, unique, strong and imperfect pearls, Mariko loves the ones which are regarded as baroque pearls which are not round and too white. After harvesting pearls, pearl farmers also harvest scallops and sell them for food. Pearl is an ethical gemstone, in the process of culturing pearls, farmers don’t waste their life.

Southsea pearl
Pearls from South sea oysters. The size of clam is larger than Akoya pearls, and the size of pearls is also as large as 8-14mm. Tahitian pearl oysters produce black pearls, while white South sea pearl oysters produce white or gold pearls. Warm seawater suits to grow them. Tahitian pearls are mainly cultured in Tahiti and White South sea pearls are cultured in Australia and Myanmar. In addition to round shapes, there are also drop-shaped (tears-shaped) and non-round Baroque pearls. South Sea pearls are considered to be more expensive than other pearls. The streaks (circles) on the surface of the pearl, sometimes seen in South Sea pearls, are traces of the pearl rotating in the shell. It’s considered as genuine proof. We use South Sea pearls of 14mm or more which is quite rare and unique. It represents presence, luxury, dignity and uniquness.

Keshi pearl
Small non-nucleated pearls typically formed as by-products of pearls caltivation. Keshi pearls are all that grew without a nucleus. Originally, keshi pearls referred to those pearls formed when a bead nucleus was rejected. More recently, keshi has been used to refer to second harvest pearls and even to freshwater non-nucleated pearls.

2. Knot

All knots: A method of making knots between pearls and stringing them. It is hard to break thread. Pearls do not fall apart when they are cut. Use this method when threading large pearls.
Stringing: A method of stringing pearls and making knots at only both ends of the necklace.

3. Maintenance
After using, please wipe the pearl with a dried soft cloth. It is affected by lighting, so keep it in a case when you store. Pearls are vulnerable to moisture and dryness, so please take them out of the case and put them in the air. Meanwhile don’t keep them in the case for a long time, wear it occasionally. It’s important to make them breathe. If you scrape or rub with hard thing, the surface will be damaged and it will lose the original lustre. Please not to allow the pearl to touch hard objects such as sharp metal. Please remove the ring when cooking, washing, bathing (hot spring), or swimming in the pool. Pearl has enough hardness to wear daily but the soaking them in the water could damage the surface and thread. (If it’s a string of necklace)

Thread change
We recommend customers to change the thread every seven years.

HAAT-ery. is a project examining archival headwear, a physical research derived from texts, images and findings. All fabrics employ techniques by hand; whether that be hand-dyeing with natural dyes, hand-waxing, hand-stitching, or reusing antique textiles collected with consideration. Fabrics have been made specifically for us within India and neighbouring regions, as ethically and sustainable as possible.

All hats are made in London with a small team of milliners. Every detail, from the lining to the threads is the result of ongoing research and learning. The imperfections of hand-crafted and aged fabrics accumulate with wear, allowing each piece to be individual.
