This elongated octagon-cut blue sapphire presents a striking inky dark navy-blue color, deep and saturated to the point of approaching midnight — a bold, almost black-blue that is instantly commanding. The step-cut octagon faceting reveals the stone's extreme color depth through clean, geometric planes, and natural needle inclusions scattered within the crystal add a distinctive, authentically natural character to this intensely saturated stone.

Deep, inky blue sapphires like this are particularly desirable in vintage and bold contemporary jewelry styles where strong, dark color saturation is the primary aesthetic goal. Entirely untreated, this stone's dramatic blue color is a wholly natural expression of earth chemistry, making it a genuine purist's choice. At 0.54ct in a 5.4x3.2mm elongated octagon, it is a refined accent stone with remarkable color impact for its modest weight — powerful for its size.

Very nice suit set. size 12. seems to fit as expected. I love the quality. It does have multi colored thread, as it is not solid.

Summer wedding kids suit
Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.

Very Modern Handsome Suit
Color: Grey, Size: 7 Years, Color: Grey, Size: 7 Years
This is an incredibly sharp looking suit for the little guy. Great price and features, too. I made a mistake in sizing up instead of down and first one was too sloppy on him and would need alterations. He is thin and very thin in the waist. There is a lot of adjustment with buttons in waistband and coat hides the bunching. This shirt and coat will easily take a fuller body than slim I believe. He loves posing in it and feels very classy. Best purchase for a formal suit that will last longer than most kids clothes size wise. Felt bad about returning but careful folding and packing got it good as new.
