Moonstone can come in many sizes and shapes like most other stones. This easily available stone is amongst the favorite of Jewellers’ list because of this reason. It is available in calibration in huge quantities and as Freesize too! The freesize moonstones are used mostly in One-stone-Pendants, which are non-replaceable as each one has a unique size and the calibration sizes (Rounds, Pears, etc) are used most in Bracelets and Earrings.

What are the other names of this gem? What are the reasons behind the fascinating blue sheen?
Many times our customers who are curious to know about gems, ask us about adularescence and scientific reason behind it. This blue light is caused by interference, diffraction and diffusion phenomenon of light by very less concentrations within the stone. On black background blue sheen appears at its best. A complete transparent big size over 15 carats piece with blue sheen all over the stone is very rare and high in prices. Astronauts from America landed on moon July 20, 1939 and later in 1970 Moonstones were declared the gemstone of Florida.

Faceted stones are hardly used in this stone because blue sheen goods at its best in cabs. Smooth beads and bracelets are also very famous and widely used and we also produce these.

Moonstone of different colors and varieties -

Blue and rainbow moonstone – This type is different from all other opaque moonstones, this comes with transparent to translucent quality. Indian material comes with rainbow firing and Sri Lankan material comes in blue firing. Sri Lankan mines have low to high quality material but high quality (Completely transparent with sheen all over the stone) is depleting now that’s why prices has been increased due to low supply. Most ofsilver jewelry manufacturers use medium quality material with medium clouds and blue sheen because it comes in low and affordable price range. When we talk about Indian moonstone then it quite resembles Sri Lankan one, only difference is that Indian quality has rainbow sheen instead of blue. In market both are categorized in same category.
