You need to find dealers who specialize in cutting tourmaline and a few other gems that form in crystals with that particular aspect ratio. It comes down to basic economics. Emerald cuts and marquises make the best use of the rough crystal shape without great weight loss. Not all gems can be cut in a long, narrow style because of differences in crystal forms or the stubbier shapes of stream-tumbled stones when mined from waterborne deposits. It=92s no accident the =93emerald cut=94 got its name because beryl occurs in longish narrow prisms that cut to that shape with very little weight loss. It=92s certainly not one of the more brilliant cuts but is ideal for stones that are valued as much for color as glitter. Natural gems often cut in long, narrow shapes include tourmaline, the beryls (emerald, yellow beryl, aquamarine, morganite, goshenite), topaz, kyanite, crystalline quartzes and spodumene (Kunzite and Hiddenite). Tourmaline is probably your best bet for =93extremely=94 long natural stones in relationship to width. Fortunately it occurs in many colors so you have plenty of variety to choose from. You may have to work directly with a cutter or mine owner to get stones of that type because the market prefers shorter lengths. Any of the man made flame-fusion corundums and spinels grown in long boules could likely be cut to the shapes you want. Again, you=92ll probably have to make arrangements with a cutter for them because that shape isn=92t much in demand commercially.
