Diamond Education

Understanding Cut

Cut refers to how precisely a diamond's facets are shaped and angled — it's the single biggest factor in how much a diamond sparkles. A well-cut diamond reflects light back through the top, creating brightness and fire; a poorly cut one can look dull even with excellent color and clarity.

Grade	What It Means
Excellent / Ideal	Reflects nearly all light that enters. Maximum brightness and fire.
Very Good	Reflects most light entering the stone. Excellent sparkle at a better value.
Good	Reflects a majority of light. Attractive brilliance, still a strong choice.
Fair / Poor	Light escapes through the sides or bottom rather than reflecting back. Noticeably less sparkle.

Diamond Education

Understanding Clarity

Clarity measures the visibility of a diamond's natural inclusions and surface blemishes — tiny characteristics formed as the stone grew inside the earth. Almost no diamond is perfectly clean, and clarity grade alone doesn't determine a stone's beauty.

Grade	What It Means
FL / IF	No inclusions visible even under 10x magnification. Exceptionally rare.
VVS1 / VVS2	Extremely difficult to see under 10x magnification, invisible to the naked eye.
VS1 / VS2	Minor inclusions, typically not visible without magnification. Excellent everyday value.
SI1 / SI2	Noticeable under magnification, occasionally visible to a keen naked eye up close.
I1 / I2 / I3	Typically visible to the naked eye on close inspection. Rarely affects durability, and offers noticeably more size and sparkle per dollar.

Diamond Education

Understanding Color

Diamond color measures how colorless a stone is, graded D (no color) to Z (noticeable warm tint). Most diamonds in fine jewelry fall in the near-colorless range, reading as bright, clean white to the eye, especially once set.

Grade	What It Means
D – F	Colorless. The highest grades, with no visible tint. Extremely rare.
G – H	Near colorless. Appears colorless to the naked eye. Excellent value.
I – J	Near colorless with a warmer white. Reads as white in most lighting, especially in yellow or rose gold.
K – M	Faint yellow tint, more noticeable in larger stones or white metal settings.
N – Z	Noticeable warm color throughout the stone.

Understanding Stone Treatment

Most colored gemstones sold worldwide — including the vast majority of sapphires, rubies, and emeralds — undergo a standard, industry-accepted treatment to enhance their natural color and clarity. This is normal practice, not a defect.

Treatment	What It Means
Heated	The most common treatment for sapphires and rubies. Permanent, stable, considered standard.
Irradiated	Used to achieve or intensify color in certain stones, such as blue topaz. Safe and permanent.
Diffusion	A surface-level color treatment, disclosed for full transparency.
Dyed	Color added to a porous stone, such as onyx or agate. Standard for these materials and always disclosed.
Not Treated	A natural stone that has had no enhancement applied — typically rarer and priced accordingly.

Frequently Asked Questions

Can’t find your answer?
Email support@sanajewels.com

Which length should I choose?

Sixteen inches sits at the base of the neck, eighteen just below the collarbone — the most versatile length — and twenty inches and above sit on the chest. If you intend to layer, choose lengths at least four inches apart so the pieces do not land on top of one another. The full table is on our Size & Fit Guide, and if the length turns out wrong you have 14 days from delivery to return it.

Are your metals real gold and silver?

Yes. Every piece is made in genuine metal — 10K, 14K, or 18K gold, or 925 sterling silver. All pieces are stamped with the corresponding metal marking.

Does this come with a warranty?

Yes. Every Sana Jewels piece is covered against manufacturing defects from the date of delivery, and a missing stone is replaced free under the same warranty. It is valid in the USA only, and any repair performed by another jeweler will void it. The full terms, including the coverage period and the limits on stone size, are in our Return & Refund Policy.
