Blue Sapphire Oval Cut Gemstone

Blue Sapphire oval cut loose gemstone

This Blue Sapphire is a natural Corundum gemstone weighing 1.8 carats, cut in the oval cut style and measuring 8 x 6.25 x 4.3 mm. It is a single stone, weighed and measured individually, and the photographs and video on this page were taken from it directly.

This blue sapphire displays the deep, saturated tone characteristic of fine corundum. Cut into a classic oval shape with crisp facet symmetry, it catches light readily from every angle. It presents a strong focal point for a bespoke jewellery project, whether you intend to mount it in yellow gold or platinum.

Corundum is exceptionally durable, ranking just below diamond on the Mohs scale. This makes the mineral a favourite among jewellers for pieces worn constantly. Collectors also value the species for its rich colour palette and historical significance as the traditional birthstone for September.

About Blue Sapphire as a Gemstone

Sapphire is the gem variety of corundum, an aluminium oxide crystallising in the trigonal system. Blue is the colour most people picture, but corundum occurs in nearly every hue, including pink, yellow, green and violet. Only red corundum takes a separate name, ruby. Trace iron, titanium and chromium drive the colour. You can read more via gemmological reference, mineral data.

Corundum forms in aluminium-rich, silica-poor settings, typically metamorphosed limestones and marbles or alkali basalts that carry crystals upward from depth. Because corundum resists weathering so well, many working deposits are alluvial, with crystals recovered from river gravels far from their original host rock.

Why You Will Love This Gemstone

💎 Classic Oval Cut

The traditional facet arrangement maximizes brilliance and fits standard commercial jewellery findings easily, saving your jeweller time during the bench work.

✨ Exceptional Durability

High hardness on the Mohs scale makes this stone suitable for everyday rings and bracelets without excessive worry about surface scratching.

🔷 Saturated Colour

The deep blue bodycolour holds its tone well under both natural daylight and artificial indoor lighting conditions.

Popular Uses

Sapphire is a mainstay of fine jewellery. At Mohs 9 it is the hardest gem material after diamond and moissanite, which makes it very well suited to rings and bracelets that face daily contact. A Blue Sapphire of this size works particularly well as the centre stone in a bespoke piece.

Ideal For

  • A bespoke ring for daily wear
  • A September birthday gift commission
  • A jeweller stocking bench materials
  • A collector of fine corundum

Frequently Asked Questions

What are the exact measurements of this Blue Sapphire?

This stone measures 8 x 6.25 x 4.3 mm and weighs 1.8 carats. Those figures are taken from the stone itself, not estimated from a category average.

How does this sapphire handle daily wear in a ring?

Corundum is one of the hardest natural minerals known. This stone stands up very well to the knocks and scrapes of everyday wear on a finger.

What metal pairs best with this shade of blue?

Traditional yellow gold creates a warm contrast that brings out the velvety depth of the blue. White metals like platinum or palladium offer a sharper, modern look.

How should I clean this gemstone at home?

Use warm soapy water and a soft brush to remove oils from the pavilion facets. Rinse thoroughly under clean running water afterwards.

Is this suitable for a first serious jewellery project?

Yes, sapphire is forgiving to set because of its toughness. It makes an excellent centre stone for a bespoke anniversary or birthday commission.

How long does delivery take, and can I return it?

We contact you directly as soon as your order is placed to arrange delivery, so you always know where the parcel is. Returns are accepted within 7 days of the date you receive the item.

Are your stones natural, or are any of them synthetic?

Everything we sell is 100% natural. We do not deal in synthetic or laboratory-grown material, and we do not hide anything about a piece: the photographs are shot to show every detail, including the ones a seller might prefer you did not see.

Will I receive the exact stone shown in the photos and video?

Yes. Each listing covers one individual stone, and the media on this page was shot from that stone. Once it sells, the listing comes down.
