"ith Diamonds" is ith's special program that provides customers with two pieces of diamonds cut from the same rough diamond. A single rough diamond is cut into a pair of diamonds to create the unique wedding rings for you and your partner.
The "ith Diamonds" initiative also emphasizes traceability, collects and stores all the datas of each diamond, start from Kimberley Process Certificate, a certificate of origin that identifies each diamond, as well as photographs of rough diamonds and Sarine Profile™, the detailed report of the diamond including design images used to cut diamonds from rough diamonds. Through these processes, we have prepared a system that traces the diamonds delivered to our customers from the place of production, through processing, to sales and distribution. Customers who choose "ith Diamonds" will be issued with an ith original certificate as proof of having gone through these processes.
The diamond 4Cs are derived from the initial letters of the four categories used to evaluate a round brilliant cut diamond.
The 4Cs are: Carat(weight), Color(shade), Clarity(transparency), and Cut(brilliance).
This standard was proposed by the GIA (Gemological Institute of America) in the mid-20th century.
By establishing clear indicators for the evaluation of diamonds, which until then had been left to the subjective judgment of jewelers, a common understanding of the objective evaluation of individual diamonds was created.
Until these days, the diamond 4Cs are accepted around the world, and well-known high jewelers also use the diamond 4Cs to evaluate diamonds.
Although often thought of as a unit of size,carats are a unit of weight for gemstones,
with one carat weighing 0.2 grams.
It is said to derive from the Greek word "Kararation," which means locust bean,
since in ancient times locust beans (carob beans) were used as weights to weigh gemstones.
Diamonds are often slightly yellowish with nitrogen,
and the closer to pure colorless transparency, the rarer and more valuable they are.
The color rating is divided into 23 alphabetical grades, from the highest grade D, to the lowest grade Z.
Clarity indicates the clarity of the diamond, which is evaluated by observing it with a 10x magnification loupe
and comprehensively evaluating the size, number, location, quality, color and prominence of inclusions,
as well as any abrasions or scratches that occurred after the cutting process.
Grades are divided into 11 grades, from "FL (flawless)" with no scratches or defects at all,
to those with inclusions visible to the naked eye.
Cut is the only element in which humans can be involved in the evaluation of a diamond.
The diamond is graded on a five-point scale based on ideal proportion, with the beauty of the polishing, technical cutting skill, and other factors being evaluated using a subtractive point system.
We can select the diamonds that best suit your tastes and preferences, or you may select the diamonds yourself.
A certificate of authenticity will be included with the diamond.
We offer a variety of diamonds to suit all budgets.
A diamond's cut grade is based on three factors: proportion (shape), polish (polish condition), and symmetry. Triple Excellent diamonds are diamonds that have been cut with the highest degree of precision and have received the highest rating of "Excellent" for all three elements. Because ith is a brand started by an artisan, we do not compromise but use only the finest diamonds cut by the skillful diamond cutters.
Among round brilliant cut diamonds, those that are finished with a certain level of symmetry show a pattern of eight arrows on the table side and eight heart marks on the culet side when viewed through a special scope. Diamonds that produce this pattern are called "Hearts and Arrows" (H&A), and are one indicator of a diamond cutter’s high level skill.
At ith, we also offer a special diamond called the Perfect H&A (Hearts and Arrows), which is evaluated from our own perspective. H&A is certified by domestic grading organizations in Japan, but there is a wide range of tolerance in the expression of patterns and considerable individual variation.
When looking through a scope, all eight hearts and arrows appear immediately. No matter how many times you look through a scope, there will always be hearts and arrows without missing one piece. The shape of the pattern should be easily identified as hearts and arrows(in the case of arrows, ones with big arrowheads and short shafts will be inspected as a beautiful shape of arrows).
When we talk about diamonds, we usually mean round brilliant cut diamonds.
However, there are a wide variety of diamond/gemstone cuttings.
At ith, we take orders with the diamond shape of your choice.
You may express yourself through the shape of the gemstone.
From princess cut diamonds to hearts or marquises.
