Unheated Ceylon Blue Sapphire 4.03 ct (4.4 Ratti) Oval – Natural Loose (Neelam)

Looking for a sapphire that's never been heated? Most sapphires sold today are heated to improve their colour. This one never has been: a natural Ceylon blue sapphire of just over 4 carats, untreated, with the calm, soft blue it came out of the ground with. It's a generous oval for an engagement ring or a statement pendant, and it's a stone many Neelam buyers look for: natural, unheated, Ceylon origin and over 4 carats.

• Mohs 9, second only to diamond

Why unheated

Heating is the standard, accepted treatment for sapphire, and it's used on most stones on the market. An unheated sapphire shows exactly the colour nature gave it. Intact natural silk, the fine needle-like inclusions you can see in this stone, is one of the signs gemmologists look for in unheated sapphire.

For the engagement ring buyer

• Over 4 carats and 10 mm long, a bold centre stone
• Oval shape looks large face-up and flatters the hand
• Soft Ceylon blue, lighter and brighter than navy sapphire
• Mohs 9 hardness, made for everyday wear
• Beautiful in a solitaire, a diamond halo or a three-stone ring

For Jyotish (Neelam) buyers

In Vedic astrology, blue sapphire (Neelam) is traditionally associated with Shani (Saturn). Many practitioners prefer a stone that is natural, unheated and from Sri Lanka, and this stone is all three, at over 4 carats. Please consult a qualified Jyotish practitioner before wearing.

A gemstone for him: the men's signet ring

At Roho Jewels, we believe men deserve beautiful gemstones too. A natural unheated Ceylon sapphire set into a signet ring is a bold, personal alternative to a plain metal signet: one-of-a-kind, full of character, and a ring he'll wear for decades and one day pass down.

• Signet face: at 10 × 8.2 mm, this stone suits a signet face of about 13–16 mm (most men choose a face of about 15–18 mm), great on the ring or middle finger
• Setting: flush (gypsy), bezel or half-bezel keeps it low and smooth, with no claws to catch on sleeves or gloves
• Depth: the stone is 5 mm deep, so ask your jeweler for a signet head at least 6 mm deep
• Metal: rich in yellow gold, sharp in white gold or platinum, rugged in oxidised sterling silver
• Wear: Mohs 9, second only to diamond, so it is tough enough for a ring worn every day
• Worn for: every day, or to mark a wedding, a graduation or a milestone birthday

Birthstone meaning
